Increasing the difference between the maximum and minimum sound pressures of a sound wave would result in
A) An increase in frequency of the tone
B) An increase in the duration of the tone
C) An increase in the loudness of the tone
D) An increase in the timbre of the tone

Question

Quizplus · Accepted Answer

The loudness of a sound is directly proportional to the amplitude or maximum sound pressure of the sound wave. Increasing the difference between the maximum and minimum sound pressures will increase the amplitude and therefore increase the loudness of the tone. Frequency (pitch) and duration are not directly affected by the amplitude, and timbre is related to the harmonic content of the sound and not the amplitude.
