| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | A binaural system using only headphones with head-related transfer functions (HRTFs) has been studied for reproducing a three-dimensional (3D) sound field. In order to get accurate reproduction, it is necessary to use the listener’s own HRTF or a suitable HRTF. For this purpose, we have proposed a conventional method that selects the nearest HRTF from an HRTF database for the listener using spectral notch frequencies which were estimated from five pinna images taken by a stereo camera. However, there are some problems such as every image needs to be taken in actual angle respectively. In order to solve these problems, we proposed a new method in which spectral notch frequencies were estimated from a 3D pinna model scanned by a handy 3D scanner. Through two objective experiments evaluating estimation accuracy of the individualized HRTFs and time spent on measurement, the results revealed that the proposed method provided a simpler and accurate HRTF personalization compared to our conventional method. | |
