Very loud sounds (over 90 dB) may not be recognized in most device. So please use it as just an auxiliary tools. Sometimes the decibel value calculated by noise detector is not as accurate as an actual noise meter (소음측정기), and this is due to some smart phone devices microphone are aligned to human voice.
