Question

Quizplus · Accepted Answer

The perception of loudness in sound is directly related to the amplitude of the waveform, so producing a waveform with a large amplitude would result in a sound perceived as very loud. Frequency and wavelength are related to the pitch of a sound and would not necessarily make it louder. Fundamental timbre does not relate to loudness either.
