The relationship of pulsed, continuous, and warble extended-high frequency thresholds.
The relationship among pulsed, continuous and warble tone 10, 12, 14, and 16 kHz thresholds of six normal hearing young adults was studied. It was found that pulsed and continuous tones elicited essentially equivalent thresholds at all frequencies tested. Warble tone thresholds were markedly better than unmodulated thresholds at 14 and 16 kHz. This threshold discrepancy is believed to be attributable to hearing the lowest frequency components of the warble tone when a sloping audiometric configuration exists. The audiologist is cautioned against using warble tones in extended-high frequency testing.
