Document Summary

Auditory space: sounds at diferent locaions create an auditory space, which exists all around, wherever there is sound. Auditory localizaion: the locaing of sounds in auditory space. The auditory system uses locaion cues to determine the locaion of sounds: binaural cues. Depend on both ears: monaural cues. Researchers explored how people can use locaion cues to locate the posiion of sounds in 3d space: azimuth. The distance of the sound source form the listener. Binaural cues for sound localizaion: use informaion from both ears to determine the azimuth of sounds, interaural ime diference (itd) Is the diference between when a sound reaches the let ear and when it reaches the right. If the source is directly in front the sound will reach both ears at the same ime. Is efecive for low-frequency sounds: interaural level diference (ild) Is based on the diference in the sound pressure level of the sound reaching the.
