The accessibility audio market is bigger than people think

There are 1.5 billion people with measurable hearing loss. Most products in the audio space are not designed for them — and that is a strategic mistake.

Most audio products are built for people with normal hearing. That isn’t a complaint about audio engineers — it’s just the default. The user research samples normal-hearing users, the product testing happens with normal-hearing testers, and the feature roadmap solves problems that normal-hearing users notice.

Meanwhile, a billion-and-a-half people have measurable hearing loss. Many of them are paying customers who are quietly walking away from products that don’t serve them. Audio AI in 2026 has a real opportunity to address this, and most of the field isn’t paying attention.

The numbers

WHO estimates ~1.5 billion people live with some degree of hearing loss. About 430 million have disabling hearing loss.
In the US alone, ~37 million adults report hearing trouble. Adoption of hearing aids among this group is around 30%.
The over-50 cohort is the fastest-growing segment in most consumer-tech markets. Hearing loss prevalence rises sharply with age — about 1 in 3 people aged 65–74 have disabling hearing loss.
Cochlear implant users are a smaller but specialised market — roughly 1 million globally — with very different needs from hearing-aid users.

That’s not a niche. It’s a quarter of the addressable population for most audio products. And yet the field treats it like one.

Why most audio products under-serve them

A few common failure modes:

“Just turn it up” as the only accommodation. Loudness isn’t a fix for hearing loss — clarity is. A bus mix that loses presence detail in cheap consumer speakers is unusable for someone with high-frequency loss even at full volume.
No subtitles or captions in non-obvious places. Tutorials, app onboarding, podcast clips embedded in marketing. Captions get prioritised on big-budget media; they get skipped on everything else.
No support for assistive audio routing. Most apps stream to the default output. They don’t check whether the user has a hearing aid paired via LE Audio or ASHA, and they don’t expose routing to the user.
Voice assistants that don’t flex. Voice-only interactions exclude users who can’t reliably understand spoken output. The fallback to text is often missing.

None of these are technically hard. They’re just things product teams didn’t prioritise because no-one on the team experienced the problem.

Why the opportunity is now

Three shifts make this a much bigger opportunity in 2026 than even three years ago:

1. Live captions are normalised

Google Live Caption shipped in 2019. Apple followed. Browsers picked it up. Captioning is no longer a “special accessibility feature” — it’s a baseline expectation on every smartphone. The infrastructure exists; the products that opt out look outdated, not the other way around.

2. LE Audio and Auracast

Bluetooth LE Audio finally landed in shipping hardware. Auracast lets a public space broadcast audio to any compatible device — including hearing aids — without pairing. This is a real change to the assistive listening landscape. Products that integrate with this layer will be remembered as the early movers.

3. AI-driven cleanup actually works now

The first decade of “AI noise reduction” was mostly oversold. The current generation (RNNoise, Krisp, Whisper-derived cleanup) is materially better. For a hearing-aid user trying to follow a Zoom call in a noisy environment, this is the difference between participation and exhaustion.

What product teams should do

Three concrete moves that don’t require dedicated accessibility teams:

Test with the highest-volume hearing-loss profile: mild-to-moderate high-frequency loss in someone aged 55+. This is the most common pattern. If your product works for them, it likely works for many other variants.
Caption everything you produce: marketing videos, tutorials, demos, onboarding voiceover. The tooling is so cheap it’s indefensible not to.
Surface assistive routing: when a user has a hearing aid or assistive listening device paired, show it. Let them know your app is streaming to it. Don’t hide the routing layer.

What HearLab is doing about this

HearLab is the lab in this family that owns the accessibility audio surface. It’s explicitly non-medical — we don’t fit hearing aids, we don’t diagnose, we don’t do clinical work. Audiologists are great at all that.

What we do is the companion layer: helping users observe their own hearing experience, log context, capture environmental tags, and share that with their professional team. It’s the layer that everyone in the audio space could build but mostly doesn’t.

If you’re building an audio product and you haven’t thought about the accessibility-audio market, you’re leaving the door open for someone else to.
