Question

Answer the problem below by applying the concept and properties of logarithmic functions

Loudness is measured in decibels. The formula for the loudness of a sound
loglog I,
is given by "dB = 10
Io
where Io is the intensity of "threshold sound", or sound
%3D
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
loglog I
10
%3D
lo
10 oglog (316 Io)
Io
%3D
= 10log[ 316 ]
= 24.9968708262...,...or 25 decibels.
Considering that prolonged exposure to sounds above 85 decibels can cause
hearing damage or loss, and considering that a gunshot from a .22 rimfire rifle has
%3D
an intensity of about I
protection when relaxing at the rifle range?
(2.5 x1013)Io, should you follow the rules and wear ear
