Outline of Final Research Achievements

This study clarifies the effect of difference of the interaural time difference on respective frequencies for cocktail party effect. First, we established a method of manipulating only the interaural time difference of each frequency. Second, we conducted listening tests to find out the when the sound image will segregated using this method under systematic conditions.
