Because amplitude varies directly with sound pressure ( A = k < sub > 1 </ sub > P ) and sound pressure varies directly with distance ( P = k < sub > 2 </ sub > d ), such that amplitude also varies directly with distance ( A = k < sub > 1 </ sub >( k < sub > 2 </ sub > d ) = k < sub > 1 </ sub > k < sub > 2 </ sub > d ), the amplitude of the sound as perceived by the listener will be greatest when the speaker is at the point in its rotation closest to the listener and least when the speaker is farthest away.

Because and amplitude

Because the speaker is constantly moving either toward or away from the listener, however, the mechanism's rotation is constantly affecting the listener-perceived sound's wavelength by either " stretching " the wave ( increasing wavelength ) or " squeezing " it ( decreasing wavelength ) -- and because frequency, i. e., pitch, is inversely proportional to wavelength, such that increasing wavelength decreases frequency and vice versa, any listener for whom the speaker's motion changes the sound's perceived amplitude ( i. e., any listener whose distance from the speaker is changing ) must also perceive a change in frequency.
