High-frequency Bekesy audiometry: IV. Normative aspects for normal-hearing young adult.

Normal-hearing young adults Ss (10 M, 20 F) produced Bekesy threshold tracings on a modified Grason - Stadler E-800 audiometer for pure tone in 2-kc/s increments from 7-19 kc/s, using as transducer an air-coupled 1/2-inch condenser microphone. Mean threshold functions and variances, the proportion of Ss responding at each frequency, and the role of sex-related differences were analyzed and discussed. Although the same was too small to yield reference equivalent threshold SPLs for high-frequency audiometry using the present apparatus and procedures, the data are useful for a future full-scale normative study.
