Read full description

Noise uses the microphone on Apple Watch Series 4 or later to track the decibel level of the sounds in the environment around you. Features • Open the Noise app to see an average of the current decibel level displayed on a level meter in real time. The app will note if the current decibel levels in your environment are “OK” or “Loud” so you can make an informed decision about your hearing health. • Use the Noise app as a complication on your watch face to conveniently see the current decibel level with a raise of your wrist. • Turn on notifications to be alerted if the decibel levels rise to a level that can affect your hearing over an extended period of exposure. • See when the environmental sound level is reduced while you are wearing AirPods Pro and AirPods Max. • The Noise app only periodically samples the decibel level and does not record or save any of the audio or sounds in your environment
