If you have tinnitus, you've probably spent hours searching for treatments online. The number of sound-based therapies available today can be overwhelming, and the marketing claims are often hard to separate from the actual science. So here's an honest, evidence-based ranking of every major sound therapy for tinnitus -- what works, what might work, and what probably doesn't.

I've ranked these based on the strength of clinical evidence, practical accessibility, and real-world results reported in peer-reviewed research. Where the evidence is mixed, I say so.

The Short Version: What Should You Actually Try?

If you don't want to read 10,000 words, here's what the research points to. No sound therapy cures tinnitus -- the science isn't there yet. But the right combination can meaningfully reduce how loud it sounds, how much you notice it, and how much it disrupts your life. Here are the five treatments worth trying, in order:

  1. Hearing aids (if you have any hearing loss, which most tinnitus patients do). This is the single most impactful first step because it addresses the root input deficit causing your brain to overcompensate. A 2023 study showed benefit even with mild loss. All-day passive treatment with no extra time commitment.
  2. Notched sound therapy (via AudioNotch). The best ratio of evidence-to-cost for actually reducing perceived tinnitus loudness. A 2025 meta-analysis of 14 RCTs showed improvements that tripled between 3 and 6 months. It targets the specific neural mechanism (lateral inhibition) rather than just covering the sound up, and you can do it while working or relaxing. AudioNotch provides the frequency-matching tools, notched music creation, and notched noise generation you need in one platform. Give it at least 3-6 months of consistent daily listening.
  3. CBT (app-based is fine). The strongest evidence of any intervention for reducing tinnitus-related suffering. It won't turn down the volume directly, but once your brain stops reacting to the sound with anxiety and frustration, many patients find the tinnitus fades into the background on its own. Apps like MindEar and Oto make this accessible for $20-50/month.
  4. Lenire (bimodal neuromodulation). The only FDA-approved bimodal device, backed by three published trials with 600+ patients. Worth trying if the first three haven't gotten you where you want to be, though it costs $4,000-$5,000.
  5. Heidelberg Neuro-Music Therapy. The dark horse. Strong RCT data (80%+ reliable improvement, sustained at 5 years), and the 5-day intensive format means you're done in a week rather than grinding through months. The catch is you have to travel to Heidelberg, Germany.

The key insight from all the research: stack your treatments. Hearing aids, notched sound therapy through AudioNotch, and CBT can all run simultaneously, and they target different mechanisms. Hearing aids restore the missing input. Notched sound therapy suppresses the hyperactive neurons generating the tinnitus signal. CBT retrains your emotional response. No single therapy is a silver bullet, but the combination gives you the best overall shot at lasting improvement.

Below is the full evidence review for every sound therapy we could find -- 14 ranked treatments plus 20+ emerging and experimental approaches.

1. Cognitive Behavioral Therapy (CBT) with Sound Enrichment

The bottom line: CBT has the strongest clinical evidence of any tinnitus intervention for reducing distress. Multiple Cochrane reviews and meta-analyses confirm it works, and the effects hold up over time. It pairs well with notched sound therapy because they target different things.

CBT for tinnitus isn't talk therapy in the traditional sense. It's a structured program that helps patients identify and change the thought patterns and behaviors that make tinnitus distressing -- catastrophic thinking, hypervigilance, avoidance of quiet environments. Many programs include a sound enrichment component (background noise or broadband sound) alongside the cognitive work.

The catch: CBT doesn't typically reduce the perceived loudness of tinnitus. It reduces the suffering. For patients who want the actual sound reduced, a neuroplasticity-based approach like notched sound therapy targets the neural hyperactivity directly. The ideal combination is both: CBT to retrain your emotional response, and notched sound therapy to work on the auditory cortex itself.

CBT is endorsed by the American Academy of Audiology, AAO-HNS, and ASHA. It's increasingly available through apps like MindEar and Oto ($20-50/month), and internet-based CBT programs have been shown to work about as well as in-person delivery. In-person sessions typically run $100-$250 each, with 6-20 sessions recommended.

2. Hearing Aids (for patients with hearing loss)

The bottom line: If you have tinnitus and any degree of hearing loss, hearing aids should be your first consideration. They address the root input deficit driving your tinnitus while providing immediate relief.

The logic here is straightforward. Most tinnitus originates from hearing loss -- when the brain loses auditory input at certain frequencies, it compensates by turning up its internal gain, and the resulting neural hyperactivity is perceived as tinnitus. Hearing aids restore that missing input, reducing the brain's need to overcompensate.

A 2021 review of 28 studies found that 68% showed positive tinnitus outcomes with hearing aids. A 2023 study found benefit even for patients with only mild hearing loss. All major manufacturers (Phonak, Oticon, Widex, ReSound, Signia, Starkey) now include built-in tinnitus sound therapy features -- broadband noise, nature sounds, or specialized tones that play alongside normal amplification.

Two manufacturer-specific approaches deserve mention:

  • Widex Zen Therapy: Uses fractal tones -- random, chime-like sounds generated by a mathematical algorithm. A controlled trial showed an average 30-point THI reduction, with 74% of subjects achieving clinically significant improvement. The tones are more pleasant than white noise for many users, and the multi-component program (fractal tones + counseling + amplification + relaxation exercises) outperforms any single component alone.
  • Signia Notch Therapy: Takes a subtractive approach -- instead of adding sound, it removes amplification at the tinnitus frequency, leveraging lateral inhibition to suppress hyperactive neurons. A double-blind controlled study found improvement in as few as 3 weeks, with 65% of patients benefiting. This is the same neuroscience behind standalone notched sound therapy, packaged into a passive, all-day treatment.

Cost is the main barrier: $2,400-$7,500 per pair, depending on the brand and technology level. Insurance coverage varies. OTC hearing aids are cheaper but may lack advanced tinnitus features.

3. Notched Sound Therapy

The bottom line: A growing body of evidence supports notched sound therapy for chronic tonal tinnitus. It's accessible, affordable, and targets the underlying neural mechanism rather than just masking symptoms.

Notched sound therapy works by taking a sound source -- music, white noise, or other broadband audio -- and removing the frequency band that matches your tinnitus pitch. When you listen to the modified sound, neurons surrounding your tinnitus frequency are actively stimulated while tinnitus-frequency neurons get no input. Through a process called lateral inhibition, the stimulated neighbors suppress the unstimulated (hyperactive) tinnitus neurons. Over weeks and months of regular listening, this repeated pattern of selective inhibition drives cortical plasticity -- the auditory cortex gradually dials down its overactivity at the tinnitus frequency.

The foundational research came from Hidehiko Okamoto and Christo Pantev at the University of Munster. Their 2010 study in PNAS demonstrated both subjective loudness reduction and measurable changes in auditory cortex activity after 12 months of notched music listening. Since then, the evidence has accumulated steadily:

  • Stein et al. (2016) ran a CONSORT-standard randomized controlled trial with 100 participants and found significant tinnitus loudness reduction after 3 months.
  • Tong et al. (2023) compared notched therapy head-to-head against TRT in 120 patients. Both worked, but notched therapy showed greater improvement with simpler processes and higher patient compliance.
  • A 2025 meta-analysis of 14 RCTs (793 patients) found significant THI improvements that grew stronger over time: -8.6 points at 3 months, -24.6 points at 6 months.

The main limitations: it only works for tonal tinnitus (you need an identifiable pitch), notched music becomes ineffective above about 8,000 Hz (though notched white noise works up to 20,000 Hz), and results take weeks to months of daily listening. One study also found that notched and non-notched sounds were equally effective at certain mixing levels, which raises questions about how much of the benefit comes specifically from the notching versus general sound enrichment.

AudioNotch is the most comprehensive platform for notched sound therapy, available on web, iOS, and Android. It provides the full toolkit: an interactive frequency-matching tuner to identify your tinnitus pitch, the ability to create notched versions of your own music, and pre-built notched white noise and other broadband sounds. Getting the frequency match right is critical to the therapy working -- AudioNotch's step-by-step tuning process is designed to make this as accurate as possible.

4. Bimodal Neuromodulation

The bottom line: The newest major category of sound therapy, backed by large clinical trials and the first FDA-approved device. Promising, but at $4,000-$5,000 it costs roughly 50-100x more than notched sound therapy for a treatment that is still under scrutiny.

Bimodal neuromodulation pairs sound with electrical stimulation of a second sensory pathway -- tongue, cheek, or neck -- to drive plasticity in the brain circuits responsible for tinnitus. The idea is that precisely timed inputs from two senses can recalibrate neural timing rules that have gone wrong, a process called stimulus-timing dependent plasticity.

Two devices are in development:

Lenire (Neuromod Devices, Dublin) combines sound through headphones with mild tongue stimulation via a 32-electrode mouthpiece. It received FDA De Novo approval in March 2023 -- the first bimodal device to clear the FDA for tinnitus. Three clinical trials totaling over 600 patients have been published:

  • The TENT-A3 controlled trial (2024, Nature Communications): 58.6% achieved clinically significant improvement with bimodal stimulation vs. 43.2% with sound only.
  • Real-world retrospective data from 212 patients showed a 91.5% responder rate with a mean 27.8-point THI improvement.

The main criticism: Lenire's earlier trials compared different stimulation settings against each other rather than using a true sham control. In TENT-A3, the sound-only control group also improved substantially (43.2%), and some researchers argue the difference between groups, while statistically significant, is modest enough that placebo effect and general sound therapy benefit could account for much of the result.

Cost: roughly $4,000-$5,000, generally not covered by insurance. Treatment involves 30 minutes twice daily for 12 weeks. Available at about 70 US clinics and through the VA.

The Susan Shore / Auricle device (University of Michigan) takes a more targeted approach, stimulating the cheek or neck to specifically target the dorsal cochlear nucleus. A 2023 JAMA study with 99 participants and a true sham control found that over 60% showed significant improvement after active treatment but not after sham -- the strongest controlled evidence for any bimodal device so far. However, it's not yet FDA-approved or commercially available, and the timeline remains unclear.

5. Tinnitus Retraining Therapy (TRT)

The bottom line: The most established clinical protocol, with 30+ years of use and strong theoretical grounding. But the best controlled studies suggest it may not outperform simpler, cheaper alternatives -- and a head-to-head trial found notched sound therapy produced greater improvement with better patient compliance.

Developed by neuroscientist Pawel Jastreboff in 1990, TRT combines two components: directive counseling (teaching patients to reclassify tinnitus as a neutral signal) and low-level broadband sound from ear-level generators set below the tinnitus volume. The key principle is partial masking -- patients must be able to hear both the tinnitus and the therapy sound simultaneously for habituation to occur.

TRT clinicians report 64-84% success rates. But these numbers come mainly from uncontrolled observational studies. When the therapy has been tested rigorously, the results are less clear:

  • The 2019 JAMA randomized trial (151 patients) compared full TRT, partial TRT, and standard of care. All three groups improved significantly. There was no meaningful difference between them. About half of participants improved regardless of which treatment they received.
  • A 2024 systematic review of 15 studies (2,069 patients) found TRT did not provide superior effects compared to tinnitus masking, counseling, notched music training, partial TRT, or standard care.
  • Cochrane reviews have consistently rated CBT as more effective than TRT for quality of life.

The interpretation that makes most sense to me: TRT works because counseling and sound enrichment work. The specific TRT protocol may not add much beyond what good basic care provides. Given that TRT costs $2,500-$7,000, takes 12-24 months, requires specialized practitioners, and is rarely covered by insurance, most patients would be better served starting with notched sound therapy -- which is far cheaper, targets the neural mechanism more directly, and showed superior results in the Tong et al. head-to-head comparison.

6. Neuromonics

The bottom line: An innovative concept with positive company-sponsored data but weak independent validation. The Cleveland Clinic found it performed no better than standard sound generators. For the price, notched sound therapy offers a stronger evidence base at a fraction of the cost.

Neuromonics was developed by Australian audiologist Paul Davis in the late 1990s. The treatment delivers spectrally modified music through a dedicated device -- the acoustic stimulus is shaped to each patient's audiogram, providing customized frequency compensation embedded in pleasant music.

The two-stage protocol is clever in theory: Stage 1 (2 months) provides substantial masking within music to offer immediate relief and build positive associations. Stage 2 (4 months) pulls back the masking so the tinnitus becomes intermittently audible within a relaxing context, promoting gradual desensitization. The whole process targets auditory, emotional, and attentional aspects of tinnitus simultaneously.

Company-sponsored trials report impressive numbers -- 86-91% success rates, with a mean 65% improvement in tinnitus disturbance. But an independent review found all three major trials were conducted by researchers with financial ties to the company, with concerns about blinding and randomization. The best independent study, from the Cleveland Clinic, compared Neuromonics to standard sound generators and found no significant difference between the two -- while noting that sound generators cost considerably less.

Neuromonics was acquired by SoundVida in July 2024 and is now primarily delivered through a mobile app ($0.99/day to $249/year). The original device-based treatment cost $4,500-$5,500.

7. Sound Masking (White Noise)

The bottom line: The oldest and most accessible approach. Provides immediate temporary relief but no lasting neural change. If you're already using white noise for comfort, consider switching to notched sound therapy -- you're spending the same listening time, but notched sound actually targets the underlying cortical hyperactivity.

Sound masking uses broadband noise -- white noise, pink noise, nature sounds -- to reduce the perceptual contrast between tinnitus and the auditory environment. About 80% of tinnitus patients experience "residual inhibition," a brief period of tinnitus suppression after the masking sound is turned off, typically lasting seconds to minutes.

The Cochrane systematic review on masking found "no strong, consistent evidence to support or refute" it as a treatment, with most studies rated as low quality. One 2018 review paper raised a more concerning point: prolonged broadband white noise exposure may drive the auditory cortex toward the same pathological state associated with tinnitus. Animal studies have shown that even non-traumatic noise exposure can reduce neural inhibition and degrade cortical sound representations. The authors called white noise therapy a potential "otolaryngology cobra effect" -- a treatment that may worsen the problem it aims to solve.

That said, masking remains useful as a short-term comfort measure, especially for sleep. White noise machines, smartphone apps (myNoise, ReSound Relief), and tabletop generators are cheap or free. Just don't expect it to change anything long-term, and consider using it strategically rather than continuously.

8. Heidelberg Neuro-Music Therapy

The bottom line: A structured, intensive music therapy protocol with surprisingly strong RCT data -- but only available at one center in Germany.

Developed at the German Center for Music Therapy Research in cooperation with the University of Heidelberg's ENT clinic, this is not the vague "music therapy" you might be picturing. It's a manualized, neuroscience-driven program delivered over 5 consecutive days (about 50 hours of treatment across 9 sessions). The protocol combines four specific modules: resonance training (vocalization exercises that stimulate cranio-cervical resonating cavities), neuroauditive cortex reprogramming (frequency discrimination exercises targeting the tinnitus frequency region), melodic intonation training (patients learn to actively filter irrelevant auditory input), and music-based tinnitus desensitization.

The clinical results are notable. An RCT found that over 80% of patients in the therapy group achieved reliable improvement, compared to 44% in a placebo music therapy group. fMRI imaging confirmed actual cortical reorganization in the auditory cortex. Perhaps most impressive: the distress reductions held up at 5-year follow-up, suggesting durable neural changes rather than a temporary effect.

The major limitation is access. The treatment is essentially only available at the Heidelberg center in Germany, which makes it impractical for most patients worldwide. The intensive 5-day format also requires travel and time off work. But for those able to make the trip, the combination of strong evidence and short total treatment duration is attractive compared to therapies that require months of daily use.

9. Amplitude-Modulated Tonal Therapy (SoundCure S-Tones)

The bottom line: FDA-cleared, with a distinct mechanism and better-than-noise results in trials. But commercially dormant.

Based on research at UC Irvine, SoundCure developed S-Tones: a carrier frequency matched to the patient's tinnitus pitch, modulated at 40 Hz. The 40 Hz amplitude modulation creates highly synchronized cortical firing that disrupts the neural patterns generating tinnitus -- a fundamentally different approach from masking (which covers tinnitus), notching (which removes the tinnitus frequency), or CR neuromodulation (which desynchronizes firing). Published trials found S-Tones reduced tinnitus loudness 1.9 times more than white noise, were 4 times more likely to provide relief, and achieved at least some suppression in 90% of subjects.

The SoundCure Serenade device was FDA-cleared and available through audiologists, but the company appears to have limited current commercial activity. The research remains relevant as amplitude-modulated approaches influence newer therapies.

10. Acoustic Coordinated Reset Neuromodulation (Desyncra)

The bottom line: Theoretically interesting but clinically unproven. The main independent replication attempt failed, and the commercial entity has dissolved.

Developed by neuroscientist Peter Tass, Acoustic CR delivers four tones clustered around the tinnitus frequency in a randomized sequence designed to break up pathological neural synchronization. The theory is well-grounded in computational neuroscience -- if tinnitus is driven by abnormally synchronized neural firing, then systematically desynchronizing those neurons should reduce the tinnitus signal.

Early studies from Tass's group looked promising: a multicenter study of 200 patients reported clinically significant improvements at 12 months. But the RESET2 trial at Nottingham University -- the major independent replication attempt with 100 participants -- produced non-conclusive results. A systematic review of 8 studies rated the overall evidence as low, noting that most positive data came from the same research group.

Practical concerns compound the scientific ones: the therapy requires 4-6 hours of daily listening, eligibility is restricted to roughly 20-25% of tinnitus patients (those with 1-2 tonal frequencies and hearing loss no greater than 35 dB), and the UK company Desyncra Tinnitus Limited was dissolved in October 2019. The technology may still be available through some clinics, but commercial support is uncertain.

11. Binaural Beats

The bottom line: Widely available and cheap, but evidence is thin and the theoretical basis for tinnitus benefit is uncertain.

Binaural beats work by playing slightly different frequencies in each ear -- for example, 400 Hz in the left and 410 Hz in the right. The brain perceives a "beat" at the difference frequency (10 Hz in this case), which is thought to entrain brainwave activity. For tinnitus, alpha-frequency binaural beats (8-12 Hz) aim to normalize the reduced alpha rhythm and elevated delta activity found in tinnitus patients' brains.

One study of 26 patients found that 10 Hz binaural beats reduced mean disturbance ratings from 5.81 to 3.06. But another study found that adding 8 Hz binaural beats to ocean sounds provided no additional benefit beyond the ocean sounds alone. The evidence base is small, and binaural beats have not been validated by any major audiology organization. Apps and online generators are essentially free, so there's little downside to trying them -- just don't expect much.

12. Phase Cancellation Therapy

The bottom line: Based on a flawed premise. Not recommended.

Phase cancellation therapy attempts to generate a sound wave with an inverted phase relative to the patient's tinnitus frequency, aiming to cancel it out the way noise-canceling headphones cancel external sound. Some early uncontrolled studies reported that 83-91% of participants experienced temporary suppression.

The problem is fundamental: tinnitus is not a sound wave traveling through the air. It's a neural signal that originates in the brain. Nerve impulses don't have "phase" in the acoustic sense, and there are no waves to cancel. A randomized double-blind crossover study confirmed that phase-shifting did not lead to significant sound cancellation, and the effect could not be attributed to the phase manipulation. Any temporary relief likely comes from ordinary residual inhibition rather than actual cancellation.

Some apps and devices still market this concept, but it is considered unsupported by mainstream audiology.

13. Tomatis Method and Auditory Integration Training (AIT)

The bottom line: No credible evidence for tinnitus. Not recommended.

The Tomatis Method uses modified music (primarily Mozart and Gregorian chant) filtered to emphasize high frequencies (8,000-16,000 Hz), delivered through specialized headphones with bone conduction. Developed by French otolaryngologist Alfred Tomatis, the theory is that intensified high-frequency stimulation "remaps" auditory processing. Berard AIT is a related method using filtered music across 20 half-hour sessions over 10 days. The American Speech-Language-Hearing Association has concluded AIT has not met scientific standards, and the FDA banned the original Audiokinetron device. Tomatis centers exist worldwide, and portable versions are commercially available, but there are no well-designed RCTs supporting either method for tinnitus.

14. Photobiomodulation / Low-Level Laser Therapy (LLLT)

The bottom line: Explicitly recommended against by clinical guidelines.

LLLT delivers low-intensity red or near-infrared laser light through the ear canal toward the cochlea, aiming to stimulate cellular metabolism and improve microcirculation. Devices like TinniTool and LUMOMED are marketed for home use. Some studies have claimed up to 88% treatment success, but a meta-analysis concluded the evidence is insufficient, and most well-designed RCTs show equal improvement in active and sham groups. The 2024 VA/DoD Clinical Practice Guideline explicitly recommends against LLLT for tinnitus.

Worth Watching: Emerging Therapies

Several newer approaches are too early to rank but worth keeping an eye on:

  • Real-time fMRI neurofeedback: Patients learn to downregulate their auditory cortex activity using real-time brain imaging as visual feedback. A 2024 prospective randomized trial published in Radiology found fMRI neurofeedback actually outperformed CBT for reducing tinnitus distress -- a striking result given that CBT is the current gold standard. The catch: every session requires an MRI scanner, making this completely impractical for routine clinical use right now. But it's a powerful proof-of-concept that volitional control of auditory cortex activity is possible and therapeutic.
  • EEG neurofeedback: A more accessible version of the same idea. Patients learn to increase alpha-band and decrease delta-band EEG activity over the auditory cortex using real-time feedback. Multiple RCTs show distress reductions sustained at 6-month follow-up. However, a 3-arm RCT found that even non-specific neurofeedback training showed comparable benefits, raising questions about whether the specific protocol matters or whether the general act of focused attention and relaxation does the work. Available at specialized neurofeedback clinics.
  • Cross-frequency de-correlating sound modulation (Newcastle University, 2025): A blinded randomized trial found tinnitus was roughly 10% quieter after six weeks of smartphone-delivered therapy. The effect persisted for at least 3 weeks after stopping. If larger trials confirm these results, the smartphone-only delivery model could make this highly accessible.
  • Low-intensity noise tinnitus suppression (LINTS): Delivers broadband noise at threshold level -- barely audible or sub-audible. A Phase II placebo-controlled trial in 2025 found significant improvement that persisted up to 4 weeks after stopping treatment. Still early, but the precision-fitting approach is interesting.
  • Vagus nerve stimulation paired with tones: Stimulating the vagus nerve (either via surgical implant or non-invasively through the ear) while playing specific tones to enhance auditory cortex plasticity. The implanted version is FDA-approved for epilepsy and depression. For tinnitus, a 2024 trial of 29 patients found no improvement in subjective measures despite brain activity changes. Non-invasive transcutaneous auricular VNS (taVNS) using devices like the NEMOS (Cerbomed, Germany) is safer and more accessible but also unproven so far. Multiple trials are ongoing.
  • Levo sleep therapy: Plays a precise digital match of your tinnitus sound through custom earbuds during sleep. One study reported a 62% reduction in perceived tinnitus after 3 months. FDA-cleared, available through audiologists ($2,000-$4,000).
  • Electrical cochlear stimulation: Direct electrical stimulation of the cochlea via an electrode placed on the round window, designed specifically for tinnitus suppression rather than hearing restoration. An open-label trial found 100% of 22 subjects achieved clinically significant THI improvement, and 36% reported complete or near-complete suppression. Invasive (requires surgery), but a 2025 study in Advanced Science showed it reversed tinnitus-related maladaptive plasticity. Multiple groups are working toward a dedicated implantable tinnitus device.
  • Auditory discrimination training: Structured exercises where patients practice distinguishing between similar sound frequencies near their tinnitus pitch. The repeated discrimination task drives cortical plasticity in the relevant frequency region. Two RCTs totaling 70 participants showed reduced tinnitus handicap maintained at 1-month follow-up. Simple in concept, but not widely available as a commercial product.
  • Stochastic resonance near-threshold noise: Delivers spectrally tailored noise at barely-audible levels, calibrated to substitute for the brain's aberrant internal neural noise. Developed at the University of Erlangen-Nuremberg. In a clinical study, tinnitus was successfully attenuated in 21 of 24 patients, with 6 reporting complete subjective silencing during stimulation. Effects were stimulation-dependent (tinnitus returned when stimulation stopped), but the mechanism is theoretically distinct from masking.
  • Harmonic sound therapy (xTinnitus): A web-based platform that creates personalized sound files shaped around the tinnitus frequency and its octave harmonics to maximize residual inhibition. In a study of 28 subjects, 89% showed reduced loudness and annoyance, with a median residual inhibition duration of 60 minutes. Combining with online CBT produced 3.3 times greater improvement than control. Commercially available at xTinnitus.com.
  • Cochleural Alternating Acoustic Beam Therapy (CAABT): A personalized approach that alternates targeted sound stimuli between ears combined with patient-chosen natural sounds. A 2024 RCT of 60 patients published in Scientific Reports found CAABT was superior to traditional sound therapy, with fMRI showing more extensive brain changes. Primarily under investigation in China.
  • Neosensory Duo: A consumer device pairing an auditory app with a vibrating wristband (haptic stimulation rather than electrical). Unlike Lenire (clinician-prescribed) or Auricle (not yet available), it can be purchased directly online. The evidence base is more limited than Lenire's three large trials, but it's one of the few bimodal approaches available without a prescription.
  • AudioCardio threshold sound conditioning: A smartphone app that identifies damaged hearing frequencies and delivers personalized sound therapy at just-inaudible levels, aiming to stimulate weakened auditory cells. Tested at Stanford and Samsung Medical Center. The company reports over 70% of regular users noticed positive changes, but independent peer-reviewed evidence is limited. App-based subscription (~$10-15/month).
  • Bone conduction sound therapy: Sound therapy delivered through bone conduction rather than air conduction, using behind-the-ear or patch-based transducers. The Tinnicare/Tinnipatch system combines a smartphone app with bone conduction delivery for personalized retraining therapy. Ultra-high-frequency stimulation (10-20 kHz) via bone conduction can induce residual inhibition and works best when residual neuronal function exists in the 10-14 kHz range. A 2025 pilot study showed promising results. The non-occlusive delivery (doesn't block the ear canal) is an advantage for patients who dislike earbuds.
  • UltraQuiet therapy: Delivers pitch-shifted music in the 10-20 kHz range via bone conduction for high-frequency tinnitus. In a small study, 8 of 9 subjects improved, with reduced masking levels and increased hearing sensitivity. However, a systematic review rated the evidence as insufficient, and patient compliance outside the lab has been poor.
  • ACUFREE multimodal device: A portable device by Tinnitech International (Rome) that simultaneously delivers personalized sound therapy plus low-frequency and high-frequency electromagnetic waves through specialized headphones. A study of 55 patients showed 73% experienced notable TFI improvements. Available in Europe, self-administered at home for 18 minutes twice daily.
  • HyperSound ultrasonic directional audio: Uses a directed beam of ultrasound that demodulates in air to create audible sound. A University of Iowa study found 72% of participants found it acceptable for masking. Short-term loudness reductions were impressive but did not persist after exposure. Limited commercial availability.
  • Progressive Tinnitus Management (PTM): Not a specific sound therapy but a 5-level stepped-care framework developed by the VA's National Center for Rehabilitative Auditory Research. It systematically escalates from education to sound therapy to CBT based on patient needs. Standard of care across the VA system, recently updated to PTM 2.0 (2024). Worth mentioning because it's how the largest tinnitus patient population in the world (US military veterans) receives treatment.

Very Early Stage

A few more approaches have appeared recently with minimal evidence but distinct concepts:

  • Digital Frequency Customized Relieving Sound (DFCRS): A Chinese app-based approach using AI to generate personalized relieving sounds matched to the tinnitus profile. A 2025 JMIR study reported 92.5% of users experienced relief, but the study design is early-stage.
  • TD Square VR Device: A Korean device (CES Innovation Award 2025) combining AI-generated stereophonic sound, VR visual feedback, and tactile feedback for cognitive tinnitus therapy. No peer-reviewed clinical data yet.
  • Neurotone AI Tinnitus Pro: An AI-powered app platform (launched November 2025) combining personalized sound therapy with CBT tools and clinician connectivity. Too new for independent evidence.

How to Think About Choosing a Treatment

A few practical takeaways from the evidence:

Start with hearing aids and notched sound therapy. If you have any hearing loss, get hearing aids -- they address the root input deficit. Then add notched sound therapy through AudioNotch. This combination tackles tinnitus from two angles: hearing aids restore the missing auditory input, while notched sound therapy actively suppresses the hyperactive neurons generating the phantom sound. Together, these two treatments cover the core neuroscience of tinnitus at a fraction of the cost of clinical programs like TRT or Lenire.

Add CBT for the distress component. If tinnitus is causing significant anxiety, sleep disruption, or difficulty concentrating, app-based CBT ($20-50/month) has the strongest evidence for reducing that suffering. It works on a completely different mechanism than notched sound therapy, so there's real benefit to running both in parallel.

Be skeptical of extreme claims. No sound therapy cures tinnitus in everyone. Treatments reporting 80-90% success rates are often using uncontrolled studies, self-selected patients, or generous definitions of "improvement." The most rigorous studies typically show moderate effect sizes with significant individual variation.

Give treatments enough time. Neuroplastic changes are gradual. The 2025 meta-analysis found that notched sound therapy improvements roughly tripled between 3 and 6 months. Jumping between treatments every few weeks doesn't give any of them a fair chance. Commit to at least 3 months of consistent daily listening before evaluating.

Don't overspend before trying the basics. Many of the most expensive treatments on this list ($2,500-$7,000 for TRT, $4,000-$5,000 for Lenire, $4,500+ for Neuromonics) have not been shown to outperform simpler alternatives in rigorous trials. Notched sound therapy via AudioNotch offers a strong evidence base, targets the specific neural mechanism, and costs a fraction of these clinical programs. It makes sense to start there and escalate only if needed.
