| Research Abstract |
The temporal structure of an acoustic signal is recognized after perceiving the occurrence of new sound events when we listen to the signal. In this study, I focused on the continuous signals with change in spectral structure and without change in loudness, and investigated which factor prescribed the abruptness that led to obvious perception of new sound event at a frequency glide, using psychophysical experiments. In the result, it was found that the abruptness was prescribed by the duration of the frequency glide.
