| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The shape of the nasal cavity and paranasal sinuses is complex and varies between individuals so that its acoustic properties are one of the sources of speaker individuality. In the present study, a method for extracting the shape of the nasal cavity and paranasal sinuses from cone-beam CT data was developed, and then three-dimensional acoustic analyses were performed for one subject using a finite-difference time-domain method. As a result, it was revealed that the maxillary and frontal sinuses generated spectral dips below 1 kHz, the right or left half of the nasal cavity acted as a main resonator at each spectral peak, and the left maxillary sinus and ethmoidal sinuses contributed to generating not only dips but also peaks. | |
