deciBel is a simple sound level meter for Android smartphones that uses the phone mic to measure sound pressure levels.
It displays current, maximum and minimum values in decibels, and generates 3 diferent kinds of sound level x time charts: Fast, Slow and Accumulated Exposition Times. The chart images may be saved to the sdcard and then downloaded or e-mailed.
Warning: deciBel is not standards compliant and should not be used to do professional or legal sound measurements.
deciBel is free, however it is supported by Google Ads.
