If you are holding small group discussions, you can raise the noise level to allow quiet talking, but not loud outbursts. When it is test-taking time, you can set the app to the lowest 'hear a pin-drop' level of quietness. The Silent Light app lets you select a target noise level that is compatible with a range of activities. The premise behind the app is simple - it uses the microphone on the iOS device to detect background noise and rewards children when they are quiet for a set amount of time.
It was written by a pair of teachers for teachers to use in the classroom or homeschool environment. Silent Light - Classroom Timer and Decibel Meter is a new app from the folks at Top Storey Apps.
