![What I Can Do
Answer the problem given below.
Loudness is measured in decibels. The formula for the loudness of a sound is
loglog I
given by "dB = 10
lo
where lo is the intensity of "threshold sound", or sound that
can barely be perceived. Other sounds are defined in terms of how many times more
intense they are than threshold sound. For instance, a cat's purr is about 316 times as
intense as threshold sound, for a decibel rating of:
dB
10 loglog i
%3!
loglog (316 lo)
= 10
10log[ 316 ]
= 24.9968708262...,..or 25 decibels.
