Unmasking the components of a complex tone with stretched harmonics
William M. Hartmann · The Journal of the Acoustical Society of America · 2007
In the unmasking paradigm [W.M. Hartmann and M.J. Goupell, J. Acoust. Soc. Am. 120, 2142–2157 (2006)], removing harmonic n of a periodic complex tone causes harmonic n+1 to be suddenly audible, though sometimes n−1 is heard instead. The unmasking experiment was repeated with harmonically stretched tones, where the frequency of the nth ‘‘harmonic’’ was proportional to the 1.32 power of n (octave ratio of 2.5 to 1). After a six-interval sequence with component n alternately on and off (1
