dB meter : Sound Meter is professional sound meter for your Android. Sound Meter is also known as sound level meter, decibel meter (dB meter), noise meter, sound pressure level meter (SPL meter). Sound Meter uses your Android's microphone to measure levels of noise or sound pressure levels and displays measured data in dB (decibels) with reference to generally known noise (provided by American Academy of Audiology) or displays the noise data on easy to read graph for the last 30 seconds of app use.
Levels of Noise In decibels (dB) according to American Academy of Audiology (www.audiology.org):
140 dB - Gun shots, fireworks
130 dB - Jackhammers, Ambulance
120 dB - Jet planes taking off
110 dB - Concerts, Car horns
100 dB - Snowmobiles

60 dB - Normal conversation
50 dB - Moderate rainfall
40 dB - Quiet library
30 dB - Whisper
20 dB - Leaves rusting
10 dB – Breathing
The high decibel value will be harmful to your physical and mental health and hearing function. You'd better avoid exposure in noisy environments.
To protect your and your family's health, detect the decibel value now!
>> Notes <<
In most android devices the microphone are assigned to human voice so manufacturers limit the maximum values, for very loud sounds(over ~100 dB) may not be measured in most device : Moto G3 (max.80), Galaxy S6 (85dB), Nexus 5 (82dB), HTC Desire(82dB)....
Please use it as just an auxiliary tools. If you need more accurate dB values, we recommend to use a real sound level meter.
