You should know that the built-in microphones were aligned to the human voice (300-3400Hz, 40- 60 dB). Therefore, the maximum values are limited by the hardware limitations, and very loud sound (100+ dB) cannot be recognized. Remember that the sound meter app is only for fun, and please use it as an auxiliary tool. Download Perfect Sound Meter today and experience a free sound measurement tool available offline!
