dB= 10 log ( I/Io)
Io = 10^-12
dB= 10 log 3.5 x10^-14/ 10^-12 = 10 X - 1.456 = - 14.56dB

Suppose we measure a sound intensity of 1 W/m2. What sound intensity level (SIL) in dB does this correspond to?
11. The sound level in decibels (dB) is given by dB-10log(101x), where x is the intensity of the sound given in W/cm2. a) Determine the sound level in dB for a sound having an intensity of 2 x 1012 W/cm b) What would be the sound level in dB if the sound intensity were doubled? 11. The sound level in decibels (dB) is given by dB-10log(101x), where x is the intensity of the sound given in W/cm2. a) Determine the...
