Abstract
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 DPOAE's evoked by pairs of excitation signals (f, f) for different excitation frequencies f, the ear is presented with first excitation signals with a first excitation frequency fand a first noise level Land secondary excitation signals with a second excitation frequency fand a second noise level L. Pulse pairs with a first pulse of the first excitation signal and a second pulse of the second excitation signal are presented in the ear, and the DPOAE's evoked thereby are captured and evaluated. A set of at least two different pulse pairs with different second excitation frequencies fis presented in one block that is repeated several times during a measuring period.
