The relationship between precursor level and the temporal effect.

摘要: Previous studies have suggested that temporal effects in masking may be consistent with a decrease cochlear gain. One paradigm used to show this is measure the level of long-duration masker required just mask short-duration tone occurs near onset. The effect revealed when signal detected at lower signal-to-noise ratio following preceding stimulation (either an extension or separate precursor). present study examined whether depends on precursor level. was 10-ms, 4-kHz tone. 200 ms. A fixed-level had same frequency characteristics as masker, and 205 either no notch wide about frequency. For given level, growth determined. These data were estimate input-output functions. results are graded gain there precursor, suppression large notch. could action medial olivocochlear reflex.
