Question

Sound Intensity The relationship between the
number of decibels β and the intensity of a sound I (in
watts per square meter) is
β = 10 log I
10−12.
(a) Determine the number of decibels of a sound with
an intensity of 1 watt per square meter.
(b) Determine the number of decibels of a sound with
an intensity of 10−2 watt per square meter.
(c) The intensity of the sound in part (a) is 100 times
as great as that in part (b). Is the number of decibels
100 times as great? Explain.
