Description

Sound Meter is also known as sound level meter, decibel meter (dB meter), noise meter, noise detector, sound pressure level meter (SPL meter).
Sound Meter uses your phone microphone to measure environmental noise or sound pressure levels in dB (decibels) with reference to generally known noise.
With this app, you can easily measure the current level of environmental noise.

Key Features:
★ Fast dB response
★ Indicate decibel by gauge
★ Show the current noise reference
★ Display Min/Avg/Max/current decibel values
★ Show the sound level graph
★ Can calibrate the decibel for each devices

Tips:
1. To get more precise measurements, you can calibrate the decibel by adding or reducing value to adjust to your particular device's microphone sensitivity.
2. Microphones in Android devices are made to record human voice, therefore the maximum noise is limited and very loud sounds cannot be recognized (in most cases above 100dB).
3. This application is a device for fun and not meant to be used in place of scientific instrumentation.
