Sound Meter - For measuring sound in classrooms

Do you ever have the problem of to much noise in the classroom, then this is the app for you. Just open the app and set the tricker value, and when ever the noise around you gets to high, a "nice" monotone sound will play, until the sound level this under the tricker level again.

Features:
Adjust tricker volume to anywhere in the range [-60; 10] dB
Adjust the monotone tone frequency in the range [256; 65536] Hz, with live preview
