Sound meter pro 2018 APK

Sound meter Pro 2018 application is demonstrates a decibel values by measure the environmental noise, shows measured dB values in different forms. You can experience tidy graphic design with high frame by this smart sound meter application.
Sound Meter is also known as decibel meter , noise detector, noise meter, sound pressure level meter (SPL meter)

Have you ever experienced the noise of the neighbors?

SPL(sound pressure level) meter application utilizes your built-in microphone to measure noise volume in decibels, and demonstrates a reference. I had adjusted a lot of android devices with an actual Sound meter 2018 (dBA).

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 and 30 db sound test). Sound Meter is calibrated to be accurate in +-2.5 dB range of actual noise level and is probably by far the most accurate sound meter on Google play.

Levels of Noise In decibels according to American Academy of audiology :
140 dB - Gun shots, fireworks
130 dB - Jackhammers, Ambulance

50 dB - Moderate rainfall
40 dB - Quiet library
30 dB - Whisper
20 dB - Leaves rusting
10 dB –Breathing
