Which of the following is true of the nature of sound?
A) Loudness is the perceptual experience of the frequency of a sound.
B) Timbre is the amount of pressure the sound wave produces relative to a standard.
C) Frequency is the perception of the sound wave's amplitude.
D) Sound waves vary in frequency as well as in amplitude.
Sound Waves
Vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear.
Frequency
The rate at which a recurring event happens, typically measured over a particular period of time.
Amplitude
The maximum extent of a vibration or oscillation, measured from the position of equilibrium.

Final Answer :
D
Explanation :
Sound waves vary in both frequency (measured in Hertz) and amplitude (measured in decibels). Frequency is the number of vibrations per second, which determines the pitch of the sound. Amplitude is the intensity or loudness of the sound wave, which is determined by the height (or depth) of the wave.
