Tentative Audiometric Threshold-Level Standards from 8 through 18 kHz

Abstract
Both ears of 100 young healthy men with no previous military noise exposure, aged 17–23 yr and normal by otoscopy but otherwise unselected, were given Békésy-type audiometry through 18 kHz with the Rudmose high-frequency ear-canal insertion transducer. Minimum audible pressures (MAP) were obtained in approximate agreement with published studies on children and on adolescent males. There is also correspondence with the British 1954 Standard MAP up to 15 kHz. It is suggested that the time is approaching for standardizing audiometry in the octave 10–20 kHz by using all available data.
