[Auditory motion aftereffects with approaching and withdrawing sound sources].
Auditory motion aftereffects with approaching and withdrawing sound sources were investigated in the free field. Radial sound moving image (approaching or withdrawing) was imitated by means of rhythmical noise impulse sequences with arising or diminishing amplitude presented through two loudspeakers placed at 1.1 and 4.5 m from the listener. The adaptation to the auditory approaching and withdrawing exposure caused changing of evaluation by listeners the test signals followed by adapting ones. Stationary test signals were perceived by listeners as moving to the direction opposite to ones presented during adaptation. Stimuli subtly moving to the adapting signals' direction were determined as stationary. The peculiarities of auditory motion aftereffects with approaching and withdrawing sound sources were similar to ones with horizontally moving sound sources.
