Soft sound : leaf rustling -20 dB, a quiet library -30 dB , computer noise is -40 dB, refrigerator noise is -50 dB, average conversation is -65 dB. Loudness: -70 dB for traffic and -75 dB for vacuum cleaner. Dangerous Sound : Semi truck -85 decibels (dB), hair dryer -80-90 decibels (dB), And food mixer -80-90 decibels (dB). Extremely loud sound : for motorcycle or subway – 90 dB, for electric drill – 100 dB, chainsaw – 110 dB, and MP3 player with loudest volume – 110 dB.
