| Outline of Final Research Achievements |
The physiological mechanisms of singing styles of traditional folk songs that are in danger of disappearing were investigated. It was suggested that Ainu singing and Iriomote Island singing have a unique singing style in the falsetto register. New methods for background noise analysis and recording, sound field analysis, and sound pressure level calibration of the microphone were proposed and implemented. A method for estimating voice quality parameters of EGG signals was also proposed and implemented as a physiological analysis method with high accuracy. These recording methods and procedures were also applied and evaluated for implementation in fieldwork.
