Outline of Final Research Achievements

In this research, we carried out (1) search for sounds that are preferable and noticeable bird and insect songs in equal sound pressure level and loudness, (2) search for sounds that are preferable and noticeable bird and insect songs in noisy environments, and (3) searching for noticeable bird and insect songs in the presence of multiple sound sources in order to realize a comfortable and easy-to-hear sound design. It was obtained from psychological reaction regarding (1) and (2) and physiological reaction concerning (3). It was found that bird and insect songs with clearer pitch are preferred and bird and insect songs with high familiarity stand out. For the bird and insect songs that stand out in the presence of multiple sound sources, no clear result was obtained.
