Do You Still Need a Hard of Hearing App
If You Already Wear Hearing Aids?

It is a fair question and it deserves a straight answer rather than a sales one. If you have spent real money on hearing aids, wear them every day, and are happy with them, does a captions app on your phone add anything?

For most people the answer is yes, but only in specific places, and it is worth knowing which ones before you decide. This is not an argument that aids do not work. It is an argument that hearing aids and live captions are answers to two different problems, and that the rooms where one runs out of road are precisely the rooms where the other starts being useful.

Two different problems wearing the same coat

Hearing loss feels like one thing from the inside. It is really two.

The first is audibility. Sounds are too quiet, or certain frequencies have dropped out, and you are simply not receiving parts of the signal. This is the problem hearing aids are built for, and they are very good at it. An aid measures what you have lost and gives it back, frequency by frequency, and in a quiet room with one person facing you the result can be close to complete.

The second is intelligibility. The sound arrives, at plenty of volume, and it still does not resolve into words. This is what people mean when they say they can hear you, they just cannot understand you. It is why a room full of talking is harder than a room full of traffic, and it is the part that amplification cannot fully fix, because turning speech up turns the noise it is buried in up with it.

Captions attack the second problem directly. They do not make anything louder. They put the words in front of your eyes, where noise cannot get at them.

How common this actually is

You are not an unusual case for asking. The National Institute on Deafness and Other Communication Disorders reports that roughly 15 percent of American adults report some trouble hearing, and that about 28.8 million U.S. adults could benefit from using hearing aids.

The gap between could and do is the striking part. From the same NIDCD statistics, among adults aged 70 and older with hearing loss who could benefit from hearing aids, fewer than 1 in 3 has ever used them, and among adults aged 20 to 69 the figure is roughly 16 percent. So the great majority of people who would be helped by aids are not wearing any, which means most people reading this are either deciding, waiting, or getting by with something else.

Getting a device has also got easier. The Food and Drug Administration established a category of over-the-counter hearing aids for adults aged 18 and over with perceived mild to moderate hearing loss, effective October 17, 2022, which can be bought without a medical exam, a prescription, or a visit to an audiologist. That has widened access considerably. It has not changed the physics of a loud room.

The five rooms where aids run out of road

Nobody needs captions in a quiet kitchen. These are the situations where hearing aid wearers most often tell you the aids are doing their best and it is still not enough.

• The loud restaurant. The classic. Speech buried in speech, hard surfaces, music, and a table you did not choose. Directional microphones and restaurant programs help genuinely, and this is still the single most complained-about room in hearing care. Our guide to hearing in a loud restaurant covers the seating and ordering side of it.
• The group table. Several conversations running at once with nobody facing you. An aid can point at one speaker at a time, and a family table has four, in rotation. That is the subject of our guide to hearing at family gatherings.
• Voices from behind and around corners. A directional aid is helping you by favouring what is in front. The person calling from the kitchen is exactly what it is designed to de-emphasize.
• Announcements and tannoys. Airports, stations, waiting rooms, drive-thru speakers. Compressed, distorted, echoing audio is hard for a person and hard for a hearing aid, and there is no face to read.
• Anything you cannot afford to mishear. A dose, a time, a platform, a diagnosis. Even a nine-in-ten chance of catching it correctly is not good enough when the tenth costs you a day, which is why we wrote separately about hearing at the doctor's office.

Notice what those five have in common. They are not quiet-room failures. They are rooms where the sound is plentiful and the meaning is not.

What a hard of hearing app adds on top

Used alongside aids rather than instead of them, a caption app does four things an aid cannot.

It gives you the word rather than an approximation of it. Aids deliver sound and your brain does the reconstruction, which is fast and usually right and occasionally confidently wrong. Text does not get reconstructed.

It holds still. Speech is gone the moment it is spoken. RoomTalk keeps the last line on screen until somebody speaks again, so a time or a name or a number stays put long enough to read twice instead of scrolling away while you are still looking down. That is what big text is for, and how live captions work covers the mechanics.

It takes the effort off. Listening hard in a difficult room is real work, and by the end of an evening the fatigue makes you worse at it. Reading a few lines is cheap by comparison, and it is often the difference between staying at the table and going home early.

It works when the aids are out. First thing in the morning, last thing at night, in the shower conversation, in the audiologist's chair, when a battery dies, when one is being repaired. A phone in your pocket has no such gaps.

It runs fully offline, so a basement restaurant with one bar of signal does not matter, and nothing leaves the phone, which answers the reasonable question of whether you are recording anyone. You are not, and the captions FAQ covers the rest.

Running both together without them fighting

They do not interfere with each other in any real sense, because one works on sound going into your ears and the other works on text appearing on a screen. Three practical notes anyway.

Watch the microphone handoff. If your aids are paired to your phone for streaming, a call or a media stream can take over the phone's microphone. Nothing breaks, but it is worth knowing so you are not confused when the screen goes quiet.

Place the phone properly. Flat on the table between you and the person you most want to follow, not in the dead centre and not next to the serving dishes. The same placement rules apply as for anyone else using captions.

Do not treat it as a step down. A surprising number of people resist captions because reaching for the phone feels like admitting the aids failed. They did not fail. They are doing the thing they are built for, all day, invisibly, and you are adding a tool for the four rooms a week where that is not enough.

Be honest about what captions cannot do

Skipping this is how people end up disappointed, so here it is plainly.

• Overlapping speakers. Speech recognition of every kind is built around one voice at a time. Three people talking over each other produces a blended line or nothing, and no app on earth solves that.
• Distance. A voice from the far end of a long table or across a hall is too far from the microphone. Captions catch the near half of a room well and the far half poorly.
• Names and unfamiliar words. Personal names, place names and jargon get mangled by every speech engine there is. Confirm numbers and dates out loud.
• Lag. Captions run slightly behind, so in a fast joke exchange you are a half step late. Aids are instant, which is one of several reasons to keep wearing them.
• They are not a hearing test. If your hearing has changed recently, especially suddenly or in one ear only, that is a medical question and no app is the right first stop.

If you are still deciding about aids

Plenty of people are somewhere in the middle: the hearing has slipped, they have not booked anything, and they are quietly withdrawing from the rooms that got difficult. That is the worst outcome available, because the withdrawal is what costs you, not the hearing.

Get it checked. Then, in the weeks or months while you decide and adjust, having the conversation in big text on the table means you do not have to sit out family dinners in the meantime. The same app keeps being useful afterwards, which is a better deal than a stopgap. Our guide to what to look for in a deaf and hard of hearing app covers how to judge one, and if you are setting this up for a parent, the best apps for hard of hearing seniors covers doing it on somebody else's phone.

When the barrier is the language, not the hearing

Worth separating, because it comes up constantly and needs a completely different tool. If somebody is speaking English and you cannot make it out, captions are right, because they show what was actually said. If they are speaking Spanish and you do not speak Spanish, captions in Spanish do not help you at all. That is a translation problem, and an offline Spanish translator that puts big English on the screen is built for it.

The short version

Hearing aids fix audibility and a hard of hearing app fixes intelligibility, and the second problem is the one that ruins evenings. Keep wearing the aids, all day, everywhere. Put the captions on the table for the loud restaurant, the group dinner, the announcement you cannot afford to miss and the phone call that matters, which we cover separately in hearing phone calls when hard of hearing. Neither one replaces the other, and using both is not a sign that anything is wrong. It is just what it looks like to stop guessing.

If you are shopping for someone who quietly struggles with this, an app set up on their phone before the next family dinner sits alongside the usual pile of vintage t-shirts and slippers, and it is the one they will actually use at the table.

Frequently Asked Questions

If my hearing aids work, why would I need a captions app at all?

Because they solve two different problems. Hearing aids work on volume and on the frequencies you have lost, and in a quiet room with one person facing you they can be close to a complete answer. A caption app works on clarity, and it comes into its own in the rooms where amplification stops helping: a loud restaurant, a group table, a station announcement, a person talking from behind you. Most people who use both do not use them at the same time all day. They wear the aids constantly and reach for captions in the handful of rooms that were always going to be hard.

Do hearing aids make noisy restaurants easy again?

They usually help and they rarely solve it. The difficulty in a loud restaurant is not that speech is too quiet, it is that speech is buried in other speech, and turning everything up turns the background up with it. Modern aids do real work here with directional microphones and noise programs, and a good audiologist can tune a restaurant program that makes a genuine difference. It is still the room that hearing aid wearers complain about most, which is exactly why reading the near half of the table in big text is a useful second option rather than an admission of failure.

Can I use a live captions app at the same time as my hearing aids?

Yes, and they do not interfere with each other, because one is working on sound going into your ears and the other is working on text appearing on a screen. Two practical notes. If your aids are paired to your phone for streaming, check that a call or media stream is not taking over the microphone, and put the phone flat between you and the person you most want to follow rather than in the middle of the table. Many people find the combination is what finally makes a hard room workable, because the aids carry the tone and the timing and the screen carries the words you missed.

What should I use while I am still deciding about hearing aids?

A caption app is a reasonable thing to have running in the meantime, and it is not a substitute for a hearing evaluation. Get the hearing checked, because sudden or one-sided change in hearing is a medical question rather than a shopping question, and a professional can tell you what type of loss you have. In the weeks or months while that is happening, being able to read the conversation means you do not have to withdraw from it, and the app keeps being useful afterwards in the rooms where aids alone are not enough.
