Tentative age-related norms for high frequency electric bone conduction audiometry

Abstract

From 172 male and female patients aged 7-71 years old and admitted in one month to a tuberculosis hospital, 150 had their highest audible electric bone conduction (EBC) frequency evaluated, prior to the commencement of any medical treatment. Various problems in establishing high frequency norms are discussed and from the results of this study tentative age-related highest frequency EBC norms are suggested. Possible clinical applications of evaluating the highest audible C frequency is suggested.
