High-frequency Békésy audiometry. V. Excursion width.
26 normally hearing young adults produced Békésy-type tracings for pure tones ranging from 7 to 19 kHz. Tones were pulsed (2.5/s) and delivered in the fixed-frequency mode. Chart rate (1 octave/min) and rate of attenuation (2.5 dB/s) were analogous to that typically used in clinical Békésy audiometry. Results indicated that subjects typically produced median excursion widths ranging from 5 to 15 dB. No systematic change in excursion width for conventional-frequency Békésy audiometry. The results of the present study were discussed regarding their utility in validation of responses to Békésy audiometry.
