Method for automatically determining an individual function of a DPOAE level map of a human or animal hearing

摘要

The invention relates to a method for the automatic determination of an individual function of a DPOAE level map with pdp, l = f (L1, L2) of a human or animal hearing, characterized in that it comprises the following steps: - reading a model function pdp, M = f (L1, L2) with model parameters of a DPOAE level map, based on a number of N DPOAE measurements of an excitation frequency pair f1, f2, each with different level pairs, L (1 ... N) 2} for a population (p) of Normal hearing, in a working memory (15) of a computer unit (10), where N ≥ 40 and p ≥ 2, - automatic presentation of n different level pairs, L (1 ... n) 2} of an excitation frequency pair f1, f2 via sound output means ( 21, 22) to an individual and detecting the corresponding DPOAE of the individual via sound receiving means (23), wherein at least the first level pair, L (1) 2} is predefined and where n N, - iteratively fitting the model function pdp, M = f (L1, L2) to the measured n DPOAE until obtaining an individual function pdp, l = f (L1, L2) with individual parameters of a DPOAE level map of the individual by the computer unit (10), output the individual function pdp, l = f (L1, L2) and / or their individual parameters at an output means (11) of the computer unit (10).
