Chapter 3, Problem 11PP

(Acoustics) The loudness of a sound is measured in units of decibels and is calculated as shown:

$10LOG\left(SL/RL\right)$

SL is the intensity of the sound being measured.

RL is a reference sound-intensity level.

Using this formula, write a C++ program that calculates and displays the decibel loudness of a busy street having a sound intensity of 10,000,000 RL. Verify your program’s result by doing a hand calculation. After verifying that your program is working correctly, use it to determine the sound level in decibels of the following sounds:

$\begin{array}{l}a.Awhisperatsoundintensity200RL\hfill \\ b.Arockbandplayingatsoundintensity1,000,000,000,000RL\hfill \\ c.Anairplanetakingoffatsoundintensity100,000,000,000,000RL\hfill \end{array}$
