Terhardt, E. (1983). Comments on "Noise-induced pitch shifts of pure and complex tones" [J. Acoust. Soc. Am. 70, 1661-1668 (1981)]. J. Acoust. Soc. Am. 73, 1069-1070
Houtsma concludes from his experimental data spectral pitch and virtual pitch are dependent on two basically different mechanisms. The purpose of these comments is to point out some reservations about his conclusions.
