Remember that loud sounds can be harmful:

130 dB is the noise of a gunshot (close range)
120 dB is the human pain threshold
110 dB may cause serious hearing damage if sustained for longer than 1 hour
100 dB may cause serious hearing damage if sustained for longer than 8 hours
80 dB may cause hearing damage if sustained longer than 8 hours
60 dB is the volume of a typical conversation
50 dB is the volume of a quiet conversation

20 dB is the threshold of human hearing

The app is based on the current calculations to determine the sound pressure level in dB. Although we have tested the values with professional equipment, we can't ensure the absolute correctness by international standard.
