Properties of sound waves Flashcards
Loudness
Describes your awareness of the energy of a sound
Key: the loudness of a sound depends on the energy and intensity of the sound wave
Pitch
Is a description of how high or how low the sound seems to a person.
Key: the pitch of a sound you hear depends on the frequency of the sound wave.
Intensity
Sound waves spread out as they travel away from the source
Decibel
The loudness of different sounds is compared
Doppler effect
The change in frequency if a wave as it’s source moves in relation to an observer
Key: the Doppler effect occurs because the motion of the source cause the waves to either get closer of spread out
Music
