The auditory after effect of continuously and brokenly approaching sound images was investigated. The images were formed by sequences of broadband noise pulses, which were linearly modulated by their amplitude. These sequences were presented through two loudspeakers, placed at a distance of 1.1 and 4.5 m from a subject. Adaptation to continuous motion caused changes in perception of continuously moving sound sources, and adaptation to broken motion induced changes in perception of brokenly moving sources. Aftereffect didn't arise when adapting and test stimuli had different qualities of motion. Regardless to the quality of motion (broken or continuous) when adapting and test stimuli had same rhythmical structure aftereffect was stronger than when the stimuli had different structures. The results allow us to assume that the ways of processing information about continuously and brokenly moving sound sources are different. |
