Hi Stefan, There is considerable work on effects of direction of level change. The bottom line seems to be that rising intensity sounds are much more salient than equivalent falling intensity sounds. (However, see work by Canévet & colleagues for a possible exception to this rule). Patterson & colleagues have also done work on "ramped" and "damped" sounds as have Stecker & Hafter. However, the duration of these sounds is quite brief in comparison to the work cited below. . Canévet, G., & Scharf, B. (1990).

The task of the subjects is to press a button when they first hear / no more hear the tone. Out of this response I try the calculate masked threshold and compare it to thresholds determined by usual procedures. Now my questions: Is anybody on the list aware of work which deals with the masked threshold of in level increasing / decreasing tones? Are there some studies which followed a similar approach? Is anybody aware of effects due to the direction of level change, especially can a lowered threshold for decreasing tones be caused by some kind of "continuity" or "priming" effect?
