Evidence-based comparison

Tinnitus treatments, compared

No single cure exists for chronic tinnitus, but several interventions have strong evidence for reducing tinnitus-related distress. This page compares the major categories — cognitive behavioral therapy, sound therapy, hearing aids, and neuromodulation — with clinical trial data and international guideline recommendations.

TL;DR CBT has the strongest evidence base for reducing tinnitus distress. Sound therapy and hearing aids add benefit when hearing loss is present. Bimodal neuromodulation (Lenire) is an FDA-authorized emerging option with positive large-trial data. No treatment reliably eliminates the tinnitus signal itself.

What are the treatment options for tinnitus?

Published clinical guidelines — including the American Academy of Otolaryngology–Head and Neck Surgery (AAO-HNS) 2014 guideline1 and the multidisciplinary European guideline (2019)2 — converge on four evidence-based categories:

TreatmentMechanismEvidence strengthTypical effect
Cognitive Behavioral Therapy (CBT)Reframes attention and emotional response to tinnitusStrong (Cochrane review 2020)Large reduction in distress; tinnitus sound unchanged
Sound therapyPartial masking, enrichment, habituationModerateSymptomatic relief, often combined with CBT
Hearing aidsRestores afferent input; reduces central gainModerate–Strong (when hearing loss present)Both hearing and tinnitus improve in many patients
Bimodal neuromodulationPaired auditory + somatosensory stimulationModerate (TENT-A1/A2, Conlon 2020/2022)Clinically meaningful TFI reduction in majority

Approximately 60–70% of patients enrolled in structured tinnitus programs (combining CBT and sound therapy) report a clinically meaningful reduction in their TFI score at 12 months.2

Sound therapy for tinnitus

Sound therapy uses external sound — broadband noise, nature sounds, music, or customized stimuli — to alter the perception of tinnitus. Three common approaches:

  • Masking — external sound at or above the tinnitus loudness to cover the internal sound
  • Partial masking / enrichment — low-level ambient sound to reduce the contrast between silence and tinnitus
  • Notched sound therapy — music or noise with a filter notch at the tinnitus frequency, aimed at reducing lateral inhibition in auditory cortex

Sound therapy rarely eliminates tinnitus on its own but is widely used as part of a multi-modal program. A 2023 systematic review concluded that sound therapy produces small-to-moderate effects on tinnitus loudness and distress when used for at least 3 months.3

Cognitive behavioral therapy (CBT) for tinnitus

CBT is the most strongly supported intervention for tinnitus-related distress. It does not change the sound itself — it changes the patient's emotional, cognitive, and attentional relationship to that sound. Typical protocols run 8–12 sessions and include psychoeducation, cognitive restructuring, exposure-based techniques, and relaxation training.

A 2020 Cochrane review of 28 randomized trials (n = 2,733) found CBT produced large reductions in tinnitus-related quality-of-life impairment and distress versus waitlist or information control, and moderate benefit versus other active interventions.4

Barriers to CBT are logistical, not clinical: limited availability of tinnitus-trained therapists, cost, and time commitment. Internet-delivered CBT (iCBT) programs have been validated in multiple trials and may close the access gap.5

Neuromodulation for tinnitus

Neuromodulation aims to alter the abnormal neural activity thought to generate tinnitus. Several modalities have been studied:

  • Bimodal stimulation — paired auditory + non-auditory (somatosensory) stimulation, leveraging multisensory integration in the dorsal cochlear nucleus. The most developed device in this class is Lenire, which pairs headphone sound with tongue electrical stimulation. The TENT-A1 (n = 326) and TENT-A2 (n = 191) trials reported 60–70% of participants achieving a clinically meaningful TFI improvement, with benefits maintained at 12 months.67 Lenire received FDA authorization (De Novo) in 2023.
  • Transcranial magnetic stimulation (rTMS) — studied extensively but with modest and inconsistent effects
  • Transcutaneous vagus nerve stimulation (tVNS) — early-stage evidence, often paired with sound
  • Implantable cochlear implants — not a tinnitus treatment per se, but frequently reduce tinnitus in patients with severe hearing loss

How does SilenEar compare?

SilenEar is under development by MediSense as a consumer-accessible tinnitus intervention. Public information available at this time:

  • Product category: personalized sound therapy combined with multi-modal neuromodulation
  • Development stage: pre-market; clinical validation in progress
  • Availability: not currently available for commercial sale in any market
  • Related free tools offered by MediSense: the frequency matching tool and TFI assessment on this site

This page will be updated with clinical-trial results and regulatory milestones as they are published. SilenEar is not listed in the comparison table above because, at the time of writing, there are no published peer-reviewed efficacy data for the product.

What does the research say overall?

Three evidence-based takeaways supported by current guidelines:12

  1. No treatment reliably eliminates tinnitus, but the distress and functional impact of tinnitus can be substantially reduced in most patients.
  2. CBT is the highest-evidence intervention for reducing tinnitus distress and should be a core component of any treatment plan for bothersome chronic tinnitus.
  3. Hearing loss should be evaluated and treated (typically with hearing aids) in every patient with chronic tinnitus, as restoring auditory input often reduces the perceived tinnitus.

Avoid unregulated supplements, "tinnitus miracle cures," and devices with no peer-reviewed data. There is no published randomized trial evidence supporting Ginkgo biloba, zinc, or melatonin as tinnitus treatments (Cochrane reviews, 2004 and 2013).8
