The Audibility of Doppler Distortion in Loudspeakers

Authors: Allison, Roy; Villchur, Edgar

AES Convention 70 · Paper 1844 · October 1981

Abstract

Although Doppler distortion in loudspeakers has been often viewed with alarm since Beers and Belar described it in 1943, the question of its significance in music reproduction has not yet been answered. In this study the audibility of Doppler distortion in simple direct radiators is investigated theoretically (by analogy to tape-machine flutter and by analysis of blind listening-room acoustic effects), and experimentally (by double-blind listening tests). The analysis predicts Doppler inaudibility for any practical cone velocity, and the experimental results provide confirming evidence.
