Equivalences between tonal audiometry, bera frequency specific abr and steady-state auditory threshold in normal hearing Equivalencias entre audiometría tonal, bera de frecuencia específica y potenciales evocados auditivos de estado estable del umbral auditivo en normoyentes

Abstract

This descriptive research with an observational method, intended to establish the equivalence of auditory threshold values obtained in 19 subjects normal listeners between 18 and 40 years surwith no history audiological, otological, vestibular and / or neurological testing by AT, BERA ee faith and PEA. The equivalence is established by reference to a normal distribution with mean 0 and standard deviation of 1, determining how many standard deviations each was natural given above or below average in transforming raw data into a standard score, also score called Z. Concluding that the behavioral and electrophysiological tests provide individual viewing test, and on the whole, however that from the results of equivalence is applicable is necessary to expand the sample and the same power to establish rules for equipment used in the Laboratory Audiology in the CUI.
