Electrodermal Responses and Tolerance Thresholds for Pure Tones

Abstract

Electrodermal responses were utilized to determine tolerance thresholds for pure tones. Tones varying in intensity from 70 to 130 dB SPL were presented 4000 at 1000, and 125 Hz respectively. Results indicated that amplitude of electrodermal responses increased with increased intensity and that responses at 1000 and 4000 Hz were consistent with previously reported subjective levels of discomfort. Levels of discomfort were never reached at 125 Hz. The results suggest that amplitude of electrodermal responses may be utilized to indicate thresholds of tolerance.
