About this app

Want to measure sound level? This is smart sound level meter app for Android!
Our decibel meter uses your built-in microphone to measure sound volume in decibels (dB) and also displays samples on helpful graph.

NOTE: Microphones in most devices are aligned to human voice and the maximum values are limited by the hardware. Very loud sounds (~90 dB and more) may not be recognized. Automatic gain control used in some devices may interfere with the operation of this noise meter.

Meter works however there is no way my little battery wall clock is rated at 40db from 6 feet away. I worked in the music industry for 10 plus years I know how to apply audio settings and understand the correlation between levels vs. distance... even went as far as 15 feet away and minimal affect... Was worth a shot but it doesn't read accurately

Excellent App!! Truly deserve the high rating. It has a very Rapid Refresh AND it even Charts the volume levels over time so you can prove to your town/landlord that you're not just sending a screenshot of a single opportune moment! Love this app for stickin it to the LIRR for idling on tracks they're no longer supposed to bother residential areas with ^-^

Great app, a bit basic (no choice of graphing display). Easy on battery life ! I used it to fine tune the noise in my sleeping environment. Note: If your phone is in a case, the mic may be obstructed and a false reading obtained. Remove your phone from it's case, or use an external microphone for best results.
