IMPORTANT information about Perfect Sound Meter: This tool is not a professional device to measure decibels. You have to know that the built-in microphones were aligned to human voice (300-3400Hz, 40-60dB). Therefore the maximum values are limited by the hardware limitation, and very loud sound (100+ db) cannot be recognized.
Remember that sound meter app is only for fun and please use it as an auxiliary tool.
