Question

Quizplus · Accepted Answer

Loudness of sound is related to the amplitude, or the strength and intensity of the sound wave. The greater the amplitude, the louder the sound. Frequency (how often the waves occur) and wavelength (the distance between each wave) affect the pitch of sound, not the loudness. Speed can affect the intensity of sound, but it is not directly related to loudness.
