Keep Your Hearing Healthy With Your Watch
Believe it or not, the Apple Watch can also help with your hearing health.
Enter the Noise app. This app will actively use your Apple Watch’s microphone to “listen” to your surroundings. If the app thinks the noise around you is too high, it’ll send you a notification suggesting that you move to other places.
You can use the Noise app on the Apple Watch Series 4 or newer models.
