Chapter 8.6, Problem 78SR

To determine

To Explain: The sound that is 10,000 times louder than the busy street traffic.

Explanation of Solution

Given information:

The table for intensity of sounds:

Watts Per Square Meter	Common Sounds
${10}^{(-11)}$	Rustling leaves
${10}^{(-10)}$	Whisper
${10}^{(-6)}$	Normal conversation
${10}^{(-5)}$	Busy street traffic
${10}^{(-4)}$	Vaccum cleaner
${10}^{(-1)}$	Front rows of rock concert
${10}^{(1)}$	Threshold of plan
${10}^{(2)}$	Military jet take off

Proof:

Consider the following table for intensity of sounds:

Watts Per Square Meter	Common Sounds
${10}^{(-11)}$	Rustling leaves
${10}^{(-10)}$	Whisper
${10}^{(-6)}$	Normal conversation
${10}^{(-5)}$	Busy street traffic
${10}^{(-4)}$	Vaccum cleaner
${10}^{(-1)}$	Front rows of rock concert
${10}^{(1)}$	Threshold of plan
${10}^{(2)}$	Military jet take off

The objective is to find the sound that is 10,000 times louder than the busy street traffic.

The sound of busy street traffic is ${10}^{-5}$ Watts per square meter.

The sound of Front rows of rock concert ${10}^{-1}$ Watts per square meter is 10,000 times louder than the sound of busy street traffic.
