Outline of Final Research Achievements |
To further research on the selection of music that can be used in music classes and that is easy for deaf and hard-of-hearing people to listen to, an experiment was conducted on the audibility of timbres with deaf and hard-of-hearing participants. The objectives of this experiment were 1) to examine the easiness of timbre audibility under the usual/everyday music listening conditions rather than in a controlled laboratory environment, 2) to identify the acoustic characteristics of easiness of timbre audibility, and 3) to examine the relationship between pitch-dependent audibility and each participant's own frequency hearing. The study of instrumental timbres revealed that recorders, often used in music classes, are difficult to listen to and that frequency-related features such as entropy and irregularity are relevant.

Academic Significance and Societal Importance of the Research Achievements |
本研究の成果は、ろう・難聴者の音色聴き取りやすさに関して、エントロピーやイレギュラリティという音響特徴量が関係している、ということを明らかにした。健聴者の音色判別については多くの研究が行われているが、ろう・難聴者の聴きやすさについての音響特徴量は新しい発見であり、学術的意義をもつ。ろう・難聴者にとっての楽器音の聴きやすさに関する結果は、ろう・難聴者が音楽の授業を受けるときに音楽を教える先生にとっての参考となるという意味で社会的意義がある。また、ろう・難聴者にとっての聴きやすい音色や音響特徴量を音楽推薦システムに取り込むことで、ろう・難聴者の音楽の世界を広げることに貢献できると考える。
