Amplitude is a hearing enhancement app for iOS that amplifies audio so you can better hear distant or quiet sounds. It features several controls to optimize the quality of the sound. Unlike other apps, the controls are located at the top in order to provide easier control adjustments when your iPad's mic is pointed towards a sound. Due to the sensitivity of the mic, you must configure Amplitude for different situations, such as listening indoors versus outdoors.
Attach earbuds to your iPad. Amplitude requires earbuds for optimal results.
Turn the iPad volume to around 50 percent to prevent loud sounds from hurting your ears when you first open the app.
Launch Amplitude, and then point your iPad towards a sound. The mic must be in the direction of the sound.
Unmute Amplitude by tapping “Mute.” Amplitude starts out muted. You can change this by tapping “Info,” and then sliding “Mute at Start” to “Off.”
Slide the Amplitude mic boost slider to adjust the mic sensitivity from within the app. Increasing the sensitivity helps draw in quieter sounds.
Do not use earbuds or headphones with a built-in mic. The mic will interfere with the iPad's mic.
Avoid windy areas as these can interfere with the mic.
Make a note of what volume level you use on your iPad and what mic boost level you use in Amplitude for different situations, so that you can quickly adjust the levels depending on the situation.
To pick up more sounds, Amplitude's developers suggest attaching a small cup or bowl to the iPad mic to better focus incoming sounds. You can also cup your hand around the mic.
Press the mic against a wall to better hear sounds from other rooms.
Save battery life by putting your iPad to Sleep Mode while using Amplitude.
