Science of Sound

The frequency of a sound wave determines

• Pitch

• Volume

• Timbre

• How much hearing loss one suffers

If two guitar strings produce the same pitch when plucked, they must be

• vibrating at the same rate

• the same length

• made of the same material

• tightened to the same tension

The amplitude of a sound wave determines:

• Pitch

• Volume

• Timbre

• How much hearing loss
