The relationship of audiometric thresholds elicited with pulsed, warbled, and pulsed-warbled tones in adults with normal hearing.
OBJECTIVE
American Speech-Language-Hearing Association (ASHA) guidelines allow pulsed and warbled tones in measuring audiometric thresholds and include test frequencies of 3000 and 6000 Hz. However, no research has examined the relationship between thresholds obtained with these stimuli at these frequencies. This study investigated the relationship between thresholds obtained with pulsed, warbled, and pulsed-warbled tones.


METHODS
Thresholds from 25 listeners were obtained using pulsed, warbled, and pulsed-warbled tones at test frequencies recommended by ASHA.


RESULTS
Thresholds elicited with pulsed, warbled, and pulsed-warbled tones did not significantly differ.


CONCLUSIONS
Findings support using pulsed, warbled, and pulsed-warbled tones for threshold measurements at the frequencies recommended by ASHA.
