Answer Details
The amplitude of a sound wave determines its loudness. The loudness of a sound is the human perception of its intensity, which is directly related to the amplitude of the sound wave. The larger the amplitude of a sound wave, the louder the sound is perceived to be. However, it is important to note that the pitch, or the perceived highness or lowness of a sound, is determined by the frequency of the sound wave, not its amplitude.
