Mini-Quiz: Diffraction Affects Blocking Noise

by Ron Kurtus (20 June 2017)

Take this Mini-Quiz to check your understanding of the lesson material.



1. What is a common way to block out highway noise?

Wearing ear plugs

A concrete wall can block out much of the noise

Using metal reflectors

2. What can happen at the upper edge of a blocking wall?

The edge reflects the noise back to the source

Birds may gather on the top edge of the wall

Sound can be diffracted downward to your yard

3. How can the diffraction be reduced?

Reducing the effect of the edge with bushes above the top

You cannot reduce diffraction

By building the wall extremely high

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.


Be clever on your solutions
