The intensity of sound is measured in decibels (dB). The level of a sound, L, in decibels, IS given by L 10 log where I is the intensity of the sound and I, is the faintest sound detectable to humans. a) Determine the level of a sound that is 20 times more intense than I, correct to the nearest decibel. viggA b) The level of sound in a quiet bedroom at night might be 30 dB, while normal conversation has a sound level of about 60 dB. How many times more intense is normal conversation than the quiet room?
