Many studies have established high-frequency audiometry norms. Unfortunately the majority presents different averages for each decade, sex and frequency together with standard deviations. In order to solve these problems we established our norms on a widespread audiometer for each sex based on a strictly normal hearing sample. We calculated the linear regression between age and hearing loss for each frequency. We propose a set of equations to predict the "normal" threshold of a subject in function of age and sex.
