Amplitude is the measure of the maximum displacement of a wave from its rest position. As sounds become louder, the amplitude of the wave increases. Frequency refers to the number of cycles of a wave that occur per second, and pitch is subjective and refers to how high or low a sound is perceived. Hertz is a unit used to measure frequency.
