Hearing loss is common, and there’s a good chance it will impact you or someone close to you in your lifetime. According to the National Center for Health Statistics, 13 percent of adults in the US have some difficulty hearing, and it’s a growing problem around the globe. The World Health Organization predicts that one in four people will have some degree of hearing loss by 2050.
Whether you struggle to hear the doorbell or follow conversations in noisy environments or you frequently find yourself cranking the TV volume up, you likely have a device in your pocket that can help. We often think of accessibility features for folks with profound hearing loss, but the truth is many of us can benefit.
Below, I’ve pooled together several smartphone features I tested with the help of family members who have varying degrees of hearing loss. I also spoke to Apple and Google to learn more about these features in iPhones and Android. Both companies claim they work with deaf and hard-of-hearing communities to gather feedback and new ideas.
Updated June 2024: We've added Apple's Live Captions feature, Google's Conversation Mode for Pixel phones, instructions for adding custom sounds for your phone to listen for, and instructions for using real-time text (RTT) or Teletype (TTY) during calls.

Ways to Prevent Hearing Loss
There are many causes of hearing loss, but a major one we can all act to avoid is sustained exposure to loud noise (85 decibels or higher). Hearing loss is often incurable, and hearing damage can leave you with permanent conditions like tinnitus (usually perceived as a ringing in the ears), so it is vital to protect your hearing in loud environments.
It can be difficult for us to accurately judge volume levels, so why not have your phone or smartwatch do it for you? Start by setting a maximum limit on your phone’s volume. We have instructions here on how to do this for iPhones and Android devices.
Apple has a couple of built-in features to help you track volume. If you connect headphones or earbuds to your iPhone or iPad, go to Settings > Control Center > Hearing. When you next connect your headphones and play audio, you can swipe down from top right for the Control Center and tap the ear icon to see the decibel level. If your headphones have a microphone, you can also turn Live Listen on to measure the noise level of your surroundings.

Own an Apple Watch (Series 4 or later, running WatchOS 6 or later)? Open the Apple Watch app on your iPhone, tap the My Watch tab, then tap Noise > Noise Threshold. You will see the WHO guidelines on exposure and can set a decibel level so your Apple Watch alerts you when the average sound level hits or exceeds that threshold for three minutes. You can review headphone audio and environmental sound levels for the past year in the Health app on your iPhone, under Hearing on the Browse tab.
Android lacks built-in volume measurement, but you can use a free app, such as Sound Meter, to measure the noise around you in decibels (although the accuracy will depend on the quality of microphones in your device).
To reduce your risk in noisy environments, such as concerts, you should wear hearing protection. Check out our Best Earplugs guide for some ideas.
How to Use Real-Time Captions on Your Phone
Google introduced Live Caption in 2019, and the feature can automatically caption videos and spoken audio on your device in real time without a Wi-Fi or cellular connection (everything happens on-device). To use it on any device running Android 10 or later, go to Settings > Accessibility > Live Caption. You can check which Android version you have by heading to Settings > About Phone > Android Version.

You can also use Live Caption in Google’s Chrome browser. Click on More (three vertical dots) > Settings > Accessibility, and toggle on Live Caption.
If you have a Pixel 2 or newer Pixel phone, you can use Live Caption for Calls, although it only works for English at the moment. This is part of Live Caption on supported devices, so you’ll be asked if you want to use it every time you make or take a call when Live Caption is toggled on, but you can go to Settings > Accessibility > Live Caption > Caption Calls to turn it on or off.
For folks with a Pixel 6 or 6 Pro (9/10, WIRED Recommends) or newer, there’s an extra option if you go to Settings > Accessibility > Live Caption > Type Responses During Calls. This lets you type responses that can be read aloud to your caller. You can also select the voice you want to use for these typed responses.
Apple's live-captioning system is still in beta, but you can try it by going to Settings > Accessibility > Live Captions, and turning on Live Captions (Beta). By default, it will work across all apps, enabling you to get captions with streaming video, FaceTime calls, videoconferencing apps, and even in-person conversations.
Live Captions (beta) requires iPhone 11 and later running iOS 16, iPad models with A12 Bionic and later, and Macs with Apple silicon, but it only appears as an option if your primary language is set to English (US) or English (Canada).
You can also go to Settings > Accessibility > Subtitles & Captioning on your iPhone to turn on Closed Captions + SDH (subtitles for the deaf or hard of hearing).
How to Use Live Transcriptions on Your Phone
Released in 2019, the Live Transcribe & Notification app for Android converts speech to text in real time on your phone screen and supports more than 80 languages. You can also use it to type responses. Any phone running Android 6.0 and up can install and use the app, but functionality is baked in on Google’s Pixel phones, where you can access it via Settings > Accessibility > Live Transcribe. You can toggle on a shortcut for quick access.

The app was inspired by Dimitri Kanevsky, a research scientist at Google who has been deaf since early childhood, and it was developed with feedback from Gallaudet University. Live Transcribe is a customizable tool. You can save transcriptions for future reference, add custom words and phrases, and even configure your phone to vibrate when someone says your name or when conversation resumes after a lull.
Apple has folded this functionality into Live Captions, mentioned in the last section. Turn it on via Settings > Accessibility > Live Captions and it will transcribe conversations.
How to Make Your Phone Listen for You
If you find that you miss visitors at your door because you don’t hear the doorbell or a knock, or you worry about not hearing a smoke alarm, your smartphone can listen for you.
Apple has a feature called Sound Recognition that you can find in Settings > Accessibility. It enables your iPhone to listen for various sounds (fire or smoke alarms, cats or dogs, doorbells, knocking, glass breaking, a baby crying, and more). If you tap Custom Appliance or Doorbell, you can add a specific sound you want your iPhone to listen for. You may also want to dip into Settings > Accessibility > Audio & Visual to toggle on LED Flash for Alerts.
Google offers a similar feature within the Live Transcribe & Notification app. It is built in on Pixel phones, but you will need to download and install the app on most other Android devices. Go to Settings > Accessibility > Sound Notifications and tap Open Sound Notifications. You can select sounds (fire or smoke alarms, sirens, dogs, doorbells, knocking, a baby crying, appliance beeping, and more) that you want your phone to listen for. Tap the cog at the top right for Settings, and you can choose Notification Preferences (including illuminating the phone’s flash to alert you) and add Custom Sounds, such as your washing machine beep, so you know when it is done.
How to Filter Sounds With Your Headphones
Whether you use wireless earbuds or wireless headphones, you can potentially get your smartphone to help you filter and amplify sound.
The Sound Amplifier app for Android lets you reduce noise, amplify quiet sounds, and boost high or low frequencies, and you can apply different settings to each ear. It requires headphones, and you can use the feature when watching videos or other media on your phone.

If you have a Pixel phone (Pixel 3 or later), you can also use Conversation Mode with headphones. Go to Settings > Accessibility > Sound Amplifier and tap Open Sound Amplifier > Phone Mic and then Conversation Mode. By pointing your phone’s camera at the person you want to chat with, or reversing the camera and having them hold your phone, you can reduce background noise and focus on your conversation partner more easily. (This feature is for bustling environments like cafés where background noise can be a problem.) Tap Adjust Sounds to access sliders for tweaking noise reduction, quiet sounds, and frequency.

Any iPhone owners with supported Apple or Beats headphones can adjust the sound to suit their hearing and improve the clarity of music, movies, phone calls, and podcasts. Go to Settings > Accessibility > Audio & Visual, turn on Headphone Accommodations, then tap Custom Audio Setup. If you go to Settings > Control Center and add Hearing, you can also use Live Listen to hear folks better by placing your iPhone microphone close to them.
If you have the AirPods Pro or AirPods Max, you can use Transparency Mode. Go to Settings > Accessibility > Audio & Visual > Headphone Accommodations > Transparency Mode, and then turn on Custom Transparency Mode and Ambient Noise Reduction to choose how much ambient noise to allow.
With the AirPods Pro (8/10, WIRED Recommends) you can also use Conversation Boost, which you can find under Transparency Mode. The feature amplifies voices, but it does mean wearing your AirPods during in-person chats. Once you have activated it and added Hearing to the Control Center via Settings, you can turn it on by opening Control Center and tweaking amplification, balance, tone, and ambient noise with a set of sliders (it will remember your preferences).
How to Use Hearing Aids With Your Phone
Apple has a Made for iPhone (MFi) hearing aid program. Connect supported hearing aids to an iPhone via Bluetooth, and you can access most of the features we outlined above for headphones on your hearing aid. For example, go to Settings > Accessibility, select Hearing Devices, and choose yours, and then Start Live Listen to use your iPhone microphone to hear people more clearly. You can also stream music or podcasts directly to your hearing aids.

MFi hearing devices usually have additional settings (it depends on the manufacturer) and can be configured from Control Center (with Hearing added) or through the Accessibility shortcut, which you can turn on and configure in Settings > Accessibility > Accessibility Shortcut.
To use hearing aids with Android phones, pair them like any other Bluetooth device by going to Settings > Connected Devices and Pair New Device. You may also have the option to pair through Settings > Accessibility > Hearing Devices and Pair New Device.
Additional features vary by phone manufacturer. Look for hearing aid compatibility (HAC) to see what your phone supports. For example, here is the Google Pixel hearing aid compatibility page. Some hearing aids can now stream music and podcasts directly to hearing aids from Android phones, but it’s wise to check compatibility before you buy.
When using hearing aids with Pixel phones you should also open the Phone app, tap the three vertical dots for Menu at the top right, and tap Settings > Accessibility to toggle Hearing Aids on.
If you don't yet have a hearing aid but think you might need one, read our guide on how to buy a hearing aid and our Best Hearing Aids guide. We also have a guide on how to stream audio to hearing aids and cochlear implants.
How to Use Real-Time Text With Your Phone
Some folks may prefer to type responses on a call, and you can do this with the real-time text (RTT) feature. Sadly, availability depends on your region and carrier. If there's no RTT option, you will likely have Teletype (TTY) support instead. (RTT is more advanced and can transmit audio as you type.)
On Android phones, open the Phone app, tap the three vertical dots for Menu at the top right, and tap Settings > Accessibility to turn on RTT or TTY. If you choose Always Visible, you can tap the RTT icon (a capital T) after dialing someone to start an RTT call, and you can tap to launch it during a call.
To review transcripts of calls on Android, open your Phone app and tap Recents, choose the call you want, and then Call Details > See Transcript.
For iPhone, you can turn on RTT or TTY in Settings > Accessibility and you can select Answer All Calls as RTT/TTY. You can also choose RTT/TTY Call when calling someone and tap the RTT/TTY icon (looks like a landline phone) to answer a call or switch to text during a call.
To review transcripts of calls on iPhone, open your Phone app and tap Recents, then the i next to the call. You will see the RTT/TTY icon next to calls with transcripts in your call history.
Why Some Android Accessibility Features Are Baked Into Pixels
You may be wondering why some hearing accessibility features are baked into Google’s Pixel phones but offered as separate apps for other Android devices. Angana Ghosh, director of product management for input and accessibility at Google, says this allows the accessibility team to try new things on Pixel, where Google designs the hardware, especially since some phones may not be capable of the same level of on-device processing.
Keeping certain features as stand-alone apps also allows for regular updates so other Android phones can benefit from the latest developments without requiring firmware updates, which are often less frequent on non-Pixel phones.
