Abstract:
When correlated noises are presented over earphones to the two ears, listeners typically form a fused compact image of the noise. However, when the noises presented to the two ears are independent, listeners tend to hear two noises: one on the left and the other on the right. In Experiment 1 we determined the minimum duration required to form auditory images by asking listeners to distinguish between a 1-s presentation of independent noises to the left and right ears, and another 1-s presentation in which the noise was correlated for x ms before switching to two independent noises. In Experiment 2, one of the noises was correlated throughout the 1-s presentation; the other started off uncorrelated before switching to correlated. Younger adults performed better than older adults in both experiments. However, the performance of younger adults was better in Experiment 2 than in Experiment 1, whereas the reverse was true for older adults. The implications of these results for age-related changes in auditory scene analysis will be discussed.
