New clinical trial: sound therapy through hearing aids eases tinnitus, even with mild hearing loss
A randomized trial found sound therapy in hearing aids eased tinnitus distress in people with mild hearing loss. See what it shows and what it does not.

Many people with tinnitus hear a hearing test result of "mild" or "normal for your age," and leave with no plan. This trial looked at those people. It found that sound therapy through hearing-aid-style devices helped them feel less bothered. If you were told your hearing is too good for help, this research is for you.
Below, we explain the research in plain language: what the team did, what it found, and what it does not show. This page is accurate as of October 12, 2026.
“The trial measured how much tinnitus disrupts daily life. It did not claim to remove the sound.”
What the trial tested
Fournier, Thai-Van, Reynard and colleagues enrolled 145 adults in France. They analyzed 128 who finished. The average age was 54. To join, a person needed a Tinnitus Handicap Inventory score of at least 38 and average hearing thresholds below 35 dB HL across 0.5 to 4 kHz. In clinic terms, that is mild loss. Many people in this range are told their hearing is "fine" and never get a hearing aid fitting. The team split participants into three groups: Placebo amplification. Devices that passed sound along without real amplification. Sound generator. Devices that played therapeutic sound. Sound generator plus amplification. Both features together. Everyone also received the same standardized counseling. That matters. Counseling alone can help, so a fair test gives it to every group. The study ran 12 weeks. The first six weeks used the assigned program only. In the last six, participants and clinicians could choose among programs.
The results
A drop of 13 TFI points counts as clinically meaningful. Both sound-therapy groups passed that bar on average. The placebo group did not. Read the right-hand column with care. "88%" reflects how people rated their own change in one group, in this trial, over 12 weeks. It is not a promise about what will happen to you.
| Group | Change in Tinnitus Functional Index (TFI) | Reported meaningful improvement (Global Rating of Change) |
|---|---|---|
| Sound generator | about −21 points | 88% |
| Sound generator + amplification | about −18 points | 77% |
| Placebo amplification | about −6 points | 33% |
What the trial does not show
No cure. The measure was distress and function, not the disappearance of the sound. Not everyone with tinnitus. The results apply to chronic, bothersome tinnitus with mild bilateral hearing loss. People with normal hearing or more severe loss were not studied here. No verdict on amplification alone. The randomized phase had no amplification-only arm. The team cannot say how much benefit came from amplification and how much from sound generation. Twelve weeks only. We do not know how long the benefit lasts. Other measures did not separate. Secondary outcomes, including sleep, anxiety and depression, improved about equally across groups. Early version. The open-access paper is an accepted-manuscript "early version." Details may change in the final text. The authors report no competing interests. Three manufacturers loaned the devices, and the funding came from AFREPA and internal funds. One more detail deserves attention. When people could pick programs in weeks 7 to 12, amplification-only programs made up more than half of use. The authors read this as support for flexible, personal fitting rather than a single winning setting.
Why this fits how we treat tinnitus
We rarely use one tool alone. A typical plan blends counseling, sound, hearing care and, for some people, neuromodulation. The trial gives research backing to two parts of that approach: sound therapy can help in mild loss, and flexibility matters. The 2014 AAO-HNSF tinnitus guideline already supports hearing aid evaluation for bothersome tinnitus with hearing loss, and it says clinicians may offer sound therapy and should recommend cognitive behavioral therapy. This trial adds new evidence in a group that clinics sometimes overlook. If you want to see how we weigh options, read tinnitus management, can hearing aids help tinnitus and Lenire for tinnitus. This week we also covered prestin and the search for a tinnitus biomarker.
What this means for you
You do not need "bad enough" hearing loss for tinnitus care to help. If tinnitus disturbs your sleep, focus or mood, and your hearing test shows only a mild change, tell us. We can look at sound-based options and other tools, and we can explain which choices fit your results. Book a tinnitus evaluation in Harrison or Somers.

Common questions
Does sound therapy cure tinnitus?
No. The trial measured how much tinnitus disrupts life, and it did not claim to remove the sound. Many people feel relief, but outcomes vary from person to person.
Do I need hearing aids if my hearing loss is mild?
Not always. The right step depends on your test results, your symptoms and your goals. An evaluation sorts that out.
What was the "placebo" in this study?
Placebo devices looked and worked like the real ones but did not amplify sound. That let researchers separate true effects from the benefit of simply wearing a device and receiving counseling.
Does the trial prove hearing aids work best?
No. It had no amplification-only group in the randomized phase. It supports sound therapy, with or without amplification, in this specific group.
How long until I would notice a change?
In this trial, people were assessed at 12 weeks. Your timeline may differ. We set expectations at your visit.
Is this the same as Lenire?
No. Lenire uses sound plus mild tongue stimulation. The trial used hearing-aid-style devices. Both belong to the wider field of sound-based care, and we discuss each when it fits.
