A PRELIMINARY STUDY OF SOME VARIABLES AFFECTING PULSED-TONE BEKESY THRESHOLDS.
Abstract
The study was performed to determine the effects of varying the period and duty cycle of a pulsed tone on the sensitivity and variability of Bekesy thresholds at several test frequencies. Ten subjects were tested using 36 combinations of these variables. It was determined that threshold sensitivity improves both with longer periods and with higher duty cycles, and that lengthening the period adversely affects intratest variability. Frequency was ruled out as a significant variable. The effects of temporal auditory summation and repetition rate of the pulses as determinents of these results are discussed. (Author)
