Decibel Meter-Sound Noise Test

Decibel Meter (Sound Meter) also referred to as a Sound Pressure Level (SPL) meter, noise level meter, decibel meter(dB meter), sound level meter, or frequency analyzer, is a highly practical tool for conducting sound level meter or measuring environmental noise-meter levels.
Decibel Meter - Free Sound Noise Test is an intelligent sound level meter application for Android!
The noise level meter or sound pressure level Meter(SPL meter), Measure environmental noise to avoid noise pollution from damaging your hearing.

- The sound meter works quickly and accurately

Attention:
The value of a decibel meter or sound level meter (dB meter) is not as accurate as the actual sound pressure level meter (SPL meter), sound level meter, decibel meter, or noise level meter because most devices align their microphones with the human voice. To solve this problem, please use an actual sound level meter or sound pressure level meter (SPL meter) as close to the decibel error as possible before use. If you don't have an actual sound pressure level meter (SPL meter), go to a very quiet place where you can't hear any sound.
