Decibel -

Understanding dB levels is crucial for hearing safety, as prolonged exposure to sounds over can cause permanent damage. Sound Level Source / Example Perceptual Context 0 dB Threshold of hearing Near silence 30 dB Whisper, quiet library Very quiet 60 dB Normal conversation 85–90 dB Lawnmower, hair dryer Danger Zone : Risk of damage over time 110 dB Chainsaw, rock concert Painful/dangerous after short exposure 140 dB Jet engine, gunshot Immediate hearing damage The "3 dB Rule" and Adding Sound

: The scale is not linear. An increase of 10 dB represents a 10-fold increase in sound intensity and roughly a doubling of perceived loudness. Decibel
