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.

Ratings and reviews

It's ok. I don't know how accurate it is, as I don't have a way to verify its readings. The graph function sounded really cool until I found out you can only see the last 60 seconds, which makes the graph useless. Also no way to save the graph that I can see. Also can't customize the appearance at all. So if you want to see dBs in real time, it works for that, but that's it. There are other free dB apps with more features.

It does not seem to be accurate, but I do not own a decibel meter to verify. That said, I use it in situations that I think I need my ear plugs and to occasionally check noise levels for sake of comparison. According to the app the sound of a 200+ person marching band at full volume in a gymnasium is just as loud as me snapping my fingers. 83db. Today my ears were hurting from the volume at an indoor rock concert. I put in my ear plugs and checked the reading out of curiosity and it said 86db.

I've been using this app with a calibrated USB mic to measure and balance sound levels from the various speakers in a home theater system. The graphical history is perfect for this, I can sample each speaker for 5 or 10 seconds and get a clear visual indication of their relative levels. It's been incredibly useful, I really appreciate it. It would be even more useful if it had an option for C weighted averaging, and the ability to control the horizontal and vertical display range.
