What is music? |
Set of tones that are pleasing to the ear. |
|
|
What determines the loudness of a sound wave? |
Amplitude of the wave (energy and intensity) |
|
|
Sonograms are made using what? |
Ultrasound technology |
|
|
Sound waves enter through which part of your ear? |
Ear canal |
|
|
What are the three sections of the ear? |

What three bones make up the middle ear? |
Hammer, anvil, and stirrup |
|
|
What makes up the outer ear? |
