| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | It is important to estimate precisely the frequency selectivity (filter shape) and the compression characteristics of the human auditory filter in the development of perceptual models for speech and acoustic signals. In the current study, we measured both of masked thresholds by notched noise experiments and an input-output function by forward masking experiment for each individual normal-hearing listener. The compressive gammachirp (cGC) filter was used for simultaneous fitting to the notched noise data and the input-output function. We demonstrated that it is possible to distinguish the common characteristics across the listeners from the individual differences in a set of parameters of the cGC filter. | |
