Abstract

Echo threshold is that critical delay of a logging signal (the echo) at which the echo is "suppressed"--i.e., at which one rather than two events is perceived. It has recently been shown that echo threshold increases in most subjects when they are exposed to a train of redundant information prior to the test stimulus presentation--that is, there is buildup of echo suppression in the presence of the preceding train [Clifton et al., J. Acoust. Soc. Am. 95, 1525-1533 (1994)]. The present investigation measured echo threshold in 25 normal-hearing adult subjects, both for isolated (baseline) test stimuli and for test stimuli preceded by a redundant train of stimuli (buildup conditions). The test stimulus was a 4-microsecond wideband noise burst pair, in which the lead burst was presented from either the left or right side (from near -45 degrees or or near (+)45 degrees in different runs), and the lag burst was presented from the opposite side. Echo delay was varied adaptively, and the subject's task was to indicate on each trial which of two alternative positions (separated by 20 degrees) the lag sources was presented from. Average echo threshold in the baseline condition was 11.2 microseconds (in agreement with previous results) an...Continue Reading
