## Question:

What is the sound intensity of a whisper at a distance of 2.0 {eq}m{/eq}, in {eq}W/m^2{/eq}? What is the corresponding sound intensity level in dB?

## Intensity:

Mathematically, the intensity of a sound wave can be calculated by dividing the power source with the surface area. The fundamental unit used to measure it is watts per meters squared (W/m2 ). It is directly related to the value of the power source.

We are given the following data:

• Distance, {eq}{r_2} = 2.0\;{\rm{m}}{/eq}

Because the intensity of whisper at {eq}{r_1} = 1\;{\rm{m}}{/eq} is...
