Explain the relationship between the physical properties of sound and the psychological experience of sound.?
What will be an ideal response?
ANSWER:
?A cycle includes the peak of the wave and the valley that immediately follows it. Counting the number of cycles in a given time frame allows us to determine the frequency of a sound wave. Traditionally, the frequency of sound waves is measured in hertz (Hz), or the number of cycles completed per second. A sound wave with a frequency of 1,000 Hz would complete 1,000 cycles per second. The frequency of a sound wave corresponds to the pitch of the sound we perceive: the higher the frequency, the higher the pitch.
?
The loudness of the sound we hear, measured in decibels (dB), corresponds to the amplitude of a sound wave. The higher the amplitude, the more pressure is exerted on the eardrum, and the louder the sound is.
