2-2 Background

In the last unit we learned that simple harmonic motion occurs when an object is "oscillating under the influence of a restoring force." These sound waves produce the various sounds we hear every day.

However, how often do we only hear one sound at a time?

What happens when there are multiple voices, instruments, or radios playing at the same time? When there are two different sound waves present at the same time they are going to interact with each other. In this unit we will learn what happens when there are multiple sound waves occurring at the same time.
