We have to estimate the maximum possible sound level in decibels of sound waves in air.

Solution:             Click For PDF Version

The intensity I of sound waves is related to the pressure amplitude, , density, , of the medium and the speed of sound in the medium, , as

For answering this problem we will use the following data:

Substituting the above data, we find that the maximum intensity of sound waves in air is

The sound level, SL, of this intensity is
