| 抄録: | In this paper, we investigated whether difference between movements in temporal envelopes of the target and background signals can improve the detectability of target signal against background signals. The movement of the signal was defined as the mean value of slopes as the first-order approximation of temporal envelope. Stimuli were generated by multiplying one of three processed temporal envelopes (movements of 88,700, and 1313 mV/s) with one of three different noise carriers (1/2-octave bandwidth at the center frequencies (CFs) of 200,525, and 1380 Hz). The auditory search experiment was carried out. Results showed that the detectability of target signal, that is, d', is improved as the difference of the movements increases, in which the CF of target signal was the same as that of the background signal. This tendency constantly appeared when the movement of the target signal was faster than that of the background signal. These results suggest that greater difference of the movements improves the detectability of the target signal. |
