>> 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.
