Quizplus · Accepted Answer

Options A and B are incorrect as loudness is the perception of amplitude, and timbre is the quality or character of the sound, not the pressure it produces. Option C is incorrect as frequency is the number of cycles per second of a sound wave, not the perception of the amplitude.
