METHOD AND DEVICE FOR EXAMINING THE FACULTY OF HEARING

摘要

In a method for examining the faculty of hearing for at least one ear of a mammal in which growth curves are determined on the basis of the measurement of DPOAEs, evoked by pairs of excitation signals (f1, f2), for different excitation frequencies f2, first excitation signals having a first excitation frequency f1 and a first sound level L1 and second excitation signals having a second excitation frequency f2 and a second sound level L2 are presented to the ear. In the ear, pulse pairs comprising a first pulse of the first excitation signal and a second pulse of the second excitation signal are presented and the DPOAEs evoked thereby are detected and evaluated. A set of at least two different pulse pairs having different second excitation frequencies f2 is presented in a block that is repeated multiply during a measurement duration.
