Dear list,

I am looking for recent papers which account for roughness in human voices with psychoacoustic models for roughness calculation (e.g. Reuter, R. Untersuchung der Rauhigkeit menschlicher Stimmen auf der Grundlage der nichtlinearen Dynamik und der Psychoakusik. PhD Diss., TU Berlin 2000).
My preliminary experiment shows that perceptual roughness of a periodic complex tone can increase as its components at low frequencies are eliminated or reduced. This appears to contradict to existing psychoacoustic models of roughness.

The stimuli and their spectra can be found at

Any hints and/or references are very appreciated.

Best,
Chen-Gia Tsai
