Chapter 16, Problem 23E

(a)

To determine

The intensity of the sound at point $A$.

(b)

To determine

The distance required to move from the source of the sound in order to have sound intensity level of one fourth of the sound intensity level as in the point $A$.

(c)

To determine

The distance required to move from the source of the sound in order to attain sound intensity level equal to the one-fourth of the sound intensity level at point $A$.

(d)

To determine

Whether the intensity of sound and intensity level of sound obeys the rule of inverse square law or not.
