Abstract
Temporal summation patterns were established for noise signals with critical-bandwidth frequency spectrums centered at 1000 and 4000 cps. Critical-bandwidth levels were calculated from group-mean masked thresholds and converted to critical-bandwidth noise signals. These measures were conducted for 9 stimulus durations ranging from 10 to 1000 msec in 10 normal-hearing, and 10 cochlearimpaired subjects. Temporal summation functions for criticalbandwidth levels and critical-bandwidth signal thresholds were in good agreement except at 4000 cps in the cochlear-impaired group. These subjects showed no change in absolute threshold for the critical-bandwidth noise signals as a function of increasing stimulus-duration time.Keywords
