Thresholds of Perception of Repetition Pitch. Conclusions Concerning Coloration in Room Acoustics and Correlation in the Hearing Organ

It is shown that Kuttruff's “temporal diffussion” A, being a measure for the number and the strength of periodic reflections in a room, is a valuable measure too for the perceived coloration of sound (“repetition pitch”) in that room caused by such periodicities (comb-filter effect).

The thresholds of perception of repetition pitch may be predicted by means of a short-time autocorrelation model of the hearing organ. A simple relation between the physiological threshold criterion and A will prove to be valid.
