5. Loudness describes what you actually hear. A sound wave of greater intensity sounds louder. (Turning volume up on something increases loudness)
7. Contains hairs that tell the brain a sound is incoming.
11. A small tightly stretched membrane that takes sound waves and bounces them around.
12. Areas of the through containing vocal cords, also known as voice box.
14. The pitch of a sound is a description of how high or low the sound seems to someone. The pitch of a sound you hear depends on the frequency of the sound wave. High frequency means, high pitch low frequency means low pitch.
15. The density of a medium is how much matter or mass there is in a given amount of space or volume.
17. Ear Contains three smallest the three smallest bones in the body which vibrate when waves hit the ear canal.
18. Vibrations or sounds too high to hear.
20. The curved surface of the outermost part of your ear

1. Vibrations or sounds too low to hear.
2. Music is a set of tones combined in ways that are pleasing to the ear.
3. effect- The apparent change in frequency as a wave source moves in relation to the listener is called the Doppler effect.
4. Loudness or sound levels is measured in decibels. The loudness of a sound you can’t really hear is about 0 DB. Each 10 DB increase in sound levels represents a tenfold increase in intensity For example, 30 dB is 10x Louder then 20 dB.
6. Describe how well sounds can be heard in a particular area.
8. Is the ability to bounce back after being disturbed. If a medium is very elastic it’s particles easily go back to their original positions.
9. Describes the sound quality you hear. The blending of the fundamental tone and overtones make up the characteristic sound quality or timbre.
10. The intensity of a sound is the amount of energy the wave carries per second through the unit area Intensity is measured in watts per square meter.
13. System of detecting reflected sound waves.
16. The sound produced when two notes that don't sound alike combine
19. A mixture of sound waves that don't sound pleasing with another.
21. Canal The curved surface of the outermost part of your ear and looks and acts like a funnel.
