Since this finding suggested that the bats might facilitate the echolocation by this pinna movement, we proposed the sound localization model based on this pinna movement. In this model, the interaural intensity differences (IID) and the sound pressure difference between two successive echoes (paired-interaural intensity differences: PIID) were used for cues to express the vertical and horizontal positions of the target respectively.In this study, we measured the IID and PIID by using two microphones (as the bat's left and right ears) and an ultrasonic transducer (target). It was found that the measured IID and PIID well agreed with the estimated values. In addition we tried to localize a position of the target (transducer) from measured IID and PIID while changing horizontal or vertical position of the transducer. Our results show that the direction of the target could be detected by using the proposed sound localization model based on the bat's alternate pinnae movement.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_1_description_25":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.14988/pa.2017.0000011134","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_15":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"同志社大学理工学研究所","subitem_publisher_language":"ja"}]},"item_1_publisher_16":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Science
