1-2 Background

Imagine yourself listening to music...

Where is the source of this sound?

What detects this sound?

What medium carries the sound from the source?

If you are listening to live music most of you will have named the source of the sound as an instrument or voice. When listening to a recording, the CD player, computer, or car speakers will be noted as the source of the sound. It is our auditory system (ears, eardrums, etc.) which detects this sound. The sound travels from the source to your auditory system through the air. In this unit, we will discover how sound waves allow this transfer to occur.
