The psychophysical study of acoustic change related to the perception of new sound events

声音信号的时间结构是在我们收听信号时感知到新的声音事件发生后识别出来的。在这项研究中，我聚焦于频谱结构变化而响度没有变化的连续信号，并利用心理物理实验研究了哪些因素规定了导致在频率滑移处对新声音事件的明显感知的突发性。结果发现，频率滑移的持续时间决定了突发性。

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.
