Caution:
The value of sound meter is not as precise as an actual Sound Pressure Level Meter (SPL meter) sound meter, this is due to most device's microphone are aligned to the human voice. To fix this, use an actual sound meter or Sound Pressure Level meter (SPL meter) to adjust decibels error as close as possible before use. If you didn't own an actual Sound Pressure Level meter (SPL meter), go to a very quiet place where sound cannot hear and adjust the reading value to 20~30dB.

The sound in threshold does not work, only vibration. Do you know why?

This is a very great app, with great visual design compared to other decibel meters, NO ADS, meaning I don't even have to bother getting a patched apk, and recoding audio capability.

Interesting that it rates my "quiet" household at almost 60db; so much noise I'm desensitized to! It's a cool app and the comparisons (rainfall, office, etc) are a nice touch!
