The science · evidence & honesty

Why this works the way it does —
and what we're honest about.

Tonolux feels like a simple game. It isn't. It's a tool for redirecting auditory attention — meditative, not competitive. Here is the evidence it rests on, where that evidence is strong, where it's mixed, and what we've promised ourselves we will never claim.

The problem

Tinnitus is an attention problem as much as a sound problem.

About 14% of adults live with tinnitus — a persistent internal sound with no external source. For most people the sound itself is not the main problem: what matters is how much of their attention it captures. The ringing is louder, more intrusive, and harder to live with when the brain is monitoring it closely.

Attention-based therapies work on a simple insight: if you can train the brain to direct its attention outward — toward external sounds — rather than inward toward the tinnitus, the tinnitus occupies less cognitive bandwidth. It doesn't disappear, but it takes up less of the day. That is the mechanism Tonolux is built around.

The hero mechanic

Auditory attention training — the approach with the most support.

What the research says

The attention pathway has the strongest evidence base for tinnitus self-management. Auditory discrimination therapy (ADT) — exercises that train the brain to attend to and distinguish external sounds — has been shown to redirect attention away from tinnitus and can diminish tinnitus perception. Neuroplasticity research supports the idea that targeted auditory cognitive training can produce lasting changes in how the brain processes sound.

The Follow exercise is a delivery vehicle for this mechanism: keeping your focus on a drifting sound is the attention redirection in action. The game framing is there because engagement is the documented failure point of every tinnitus app. The research shows that~70% of health app users abandon within 100 days — most often because of cost or lack of engagement. Tonolux is built to be the one people actually open.

Secondary mode

Notched sound — promising, but honestly mixed.

Tailor-made notched music therapy (TMNMT) removes the listener's tinnitus frequency from audio, with the goal of quieting overactive neurons via lateral inhibition. Some trials show higher compliance and meaningful subjective relief compared to traditional tinnitus retraining therapy.

This is why Tonolux's drift-off sleep mode uses a personalized notched soundscape — it's a genuine mechanism, not just ambient noise.

The honest caveat

A 2024 meta-analysis found mixed evidence: large effect sizes in some trials, but non-significant tinnitus handicap change overall. Notched therapy works best for tinnitus at or below 8 kHz; consumer headphones are uncalibrated, so very high-pitched tinnitus matches less precisely. This is why the notched soundscape is a secondary mode, not the headline feature.

What we'll never claim

Wellness, not cure.

What we claim
May help you manage, cope with, or tune out the ringing. Many people find attention training genuinely helpful for reducing how much of their day the tinnitus occupies. It takes time, results aren’t immediate, and it won’t work for everyone.
What we’ll never claim
Reduces, cures, treats, or removes tinnitus. Tonolux is not a medical device and is not a substitute for professional care. Nothing is guaranteed.

Wellness tool — not a medical device. Please see a doctor or audiologist for tinnitus that is new, sudden, one-sided, or pulsatile, or any tinnitus that comes with hearing loss, dizziness, ear pain, or discharge. This app is not a substitute for professional care.

Market gap & what people with tinnitus want

~75% of people with tinnitus have never used a tinnitus app — a discovery gap, not a saturation problem.

Engagement & abandonment — design rationale
[11]

~70% of health app users leave within 100 days; cost and lack of engagement are key drivers.

[12]

Cost is a critical abandonment driver; users want affordable solutions.

[13]

Regular self-monitoring (like a daily check-in) is a strong predictor of long-term engagement.

Sound-therapy compliance ~32% in a monitored trial — illustrating why engagement design is not optional.

Game-based training — the caveat (NCT/PubMed)
[15]
Game-based frequency-discrimination trainingSearchfield et al. (RCT) · 2014

Game-based training raised intrinsic motivation but did NOT significantly reduce tinnitus severity vs. non-game training. Used to calibrate our honest positioning — we don't overclaim game mechanics alone.
