Noise Meter : Sound Meter

Using this app, you can quickly determine the strength of noise in decibels using your mobile device.

The Noise Meter : Sound Meter app allows you to measure the strength of noise using your smartphone's microphone. In the program window you will also be able to check the reference values of sound pressure.

Note that most input paths of modern smartphones are tuned to human voice (300-3400 Hz, 40-60 dB), so devices may "cut out" out-of-band signals. Also, the level of the input signal can be limited by hardware: for example, on Motorola Droid devices the maximum value is 100 dB, on Galaxy S - 81 dB, and on Galaxy S2 - 98 dB. At the same time, many devices have already been calibrated with a real dBA sound level meter.

The Noise Meter program can be downloaded completely free of charge. However, there is a full (paid) version of the program which has a number of advantages such as no ads, availability of calibrated additional models, sound pressure graph, the ability to set notifications by signal level, statistics menu and the ability to save log data, and a built-in vibrometer.

If you like this app, we also recommend installing other tools from Smart Tools: Ruler, Angle Meter, Smart Compass for Android, Metal Detector, Rangefinder: Smart Measure, Rangefinder: Smart Distance, Speed Meter, Thread Pitch Meter, Flashlight, Magnifying Glass, Mirror and Vibrometer.
