Subject: Threshold of increasing/decreasing tones From: Stefan Kerber <kerber@xxxxxxxx> Date: Wed, 15 Feb 2006 16:17:31 +0100Dear list I am trying to determine masked threshold by the following procedure: Subjects hear a masking noise in which a tone linearly increases/decreases in level. 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?
