The simplified HF E-800 high-frequency audiometer: clinical applications

In a prior study (Gauz and Smith, J. Aud. Res., 1985, 25, 101-122) threshold tracings were collected at 8-20 kc/s on 108 Ss using a Bekesy-type Simplified High-Frequency Audiometer (SHF E-800) set in the fixed-frequency mode. Of these, 23 Ss did not meet screening criteria for a normative study; their data are reported here. Examples are given of HF audiometric results on Ss with one or more conditions affecting hearing thresholds, including age, conductive pathologies, noise exposure, cardiovascular disorders, hearing loss in the conventional audiometric frequencies, and a miscellaneous category. Results were obtained generally in line with expectations based on literature review. The present case studies provide information useful in the clinical application of HF audiometry.
