Dynamic auditory localization: perceived position of a moving sound source.

Experiments are presented in which a sound source was moved at 15.2 cm/s over a horizontal path of 60 cm length, positioned at a 57 cm distance in front of the observer, symmetrically relative to the median plane. The subjects had to localize the sound at different moments of time. The sound source was predominantly mislocated in the direction of the movement; the mislocation increased at the end of the movement by up to 10-11 deg. In another condition the sound source was localized when it was stationary. In this case the mislocation was directed towards the median plane. The differences between the static and dynamic auditory localization are discussed.
