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.

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.

This is a really good product. I use it to check the noise level in and around my house. I have a person on the Autistic spectrum and too much noise can be very disruptive so it lets me know if the area is becoming a trigger to his disregulation. It also help us to understand when he needs to lower his voice or his TV at night. I opted to pay to remove the ads as some other sound meters had way too many ads. Hey for less than $2, I get a great tool versus pay $20 - $40 for a dedicated device.

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 ^-^
