Decibels for iOS measures sound levels in your surroundings using the built in microphone (or any microphone you connect to the device).
It's an easy (and free) way to make sure your ears are protected.
● Using the app at a party or other loud places makes you aware of the sound levels in your surroundings.
● Keeping sound levels to a minimum in your bedroom is important to get a good night sleep.
● Your home should be below 30 decibels at night. This is important to keep your mind at ease.
Keep using the app to protect your ears. It's literally only a tap away.
