It’s possible that users with hearing impairments can’t detect certain sounds. Therefore, when a sound is detected, provide feedback using a visual or vibration alert.
Mute all sounds
Prevent users with hearing loss from disturbing people around them with unexpected sounds generated from their devices.
Left/right sound balance
For people with a different degree of hearing loss in each ear, provide an option through which they can change the left/right volume ratio.
For users with hearing loss in one ear, provide an option through which they can change the audio setting to Stereo or Mono when they use earphones.
