Effects of listener sophistication on respiration audiometry. 1977

K S Jones, and F N Martin

Thirty normal-hearing college-age adults were tested by standard and respiration audiometry (RA) at 1000 Hz to investigate the effects of subject knowledge of the RA procedure. Three levels of sophistication were employed: (1) no knowledge, (2) full knowledge, and (3) deception. No significant effects on RA thresholds were revealed as a function of subject knowledge. RA itself was found to be less satisfactory as a means of measuring auditory threshold because of the difficulty in obtaining responses from some subjects and the degree of subjectivity required to judge responses.

D001299	Audiometry	The testing of the acuity of the sense of hearing to determine the thresholds of the lowest intensity levels at which an individual can hear a set of tones. The frequencies between 125 and 8000 Hz are used to test air conduction thresholds and the frequencies between 250 and 4000 Hz are used to test bone conduction thresholds.	Audiometries
