[Auditory approach and withdrawal aftereffects with low- and high-frequency free sources]
Abstract:
Short adaptation to sound source approach and withdrawal was carried out within five seconds in free field. Moving adapting and test stimuli were created by means of sequences of low- and high-frequency band noise pulses (0.05-1 kHz and 3-20 kHz) that were changed linearly in amplitude at contrarily directions with two unmoving dynamics. The auditory approach and withdrawal aftereffects were evaluated with the total indexes characterized the shifts of psychometric curves received in different listening conditions for group of eight subjects with normal hearing. Motion aftereffects were observed in case of the spectrum range coincidence for adapting and test stimuli. The effect was at adaptation to approaching and withdrawing high-frequency noise sources, but for low-frequency noise sources one was only at adaptation to approach. The radial motion aftereffects were not revealed in case of discrepancy between spectrum range of adapting and test stimuli. Thereby, the frequency tuning of auditory aftereffect was shown at adaptation to approaching and withdrawing sound stimuii.
