• Pitch

• Frequency

High frequency waves make

• high pitch sounds

• low pitch sounds

• loud sounds

• soft sounds

Birds chirping would be a _________________ sound.

• low pitch

• high pitch

• low frequency

• tall amplitude

Low frequency waves make

• high pitch sounds

• low pitch sounds

The pitch of a sound depends on the ___ of the sound wave.

• amplitude

• intensity

• frequency

• loudness

The ___ energy a sound wave has, the softer it sounds.

• less

• more

• full

The measure of how high or low a sound is:

• the intensity
