Problem 26PE

An 8-hour exposure to a sound intensity level of 90.0 dB may cause hearing damage. What energy in joules falls on a 0.800-cm-diameter eardrum so exposed?

Step-by-Step Solution:
Step 1 of 3

Solution 26PE

Prolong exposure to the high intensity sound may cause temporary or permanent damage to the hearing system.

The expression to find the intensity level of sound is,

= (10 dB)  ()

Rearrange the expression,

 =  ()

Here  is sound in decibel,  is intensity of sound and  is reference intensity of sound.

Substitute, 90 dB for  and  for in the expression of intensity level of sound,

 =  

        9 =  

Take antilog at base 10 both sides,

=

    x

      = 1.0 x w/

Therefore intensity of sound for 90 dB is 1.0 x w/

The...
