Long term stability, influence of the head position and modelling considerations for evoked otoacoustic emissions

This paper presents the results of two experiments on evoked otoacoustic emissions (EOAEs). The first experiment was conceived to study in the same subjects the temporal stability of the response waveforms, over a period of about four years. A second experiment studied the influence of the relative position between the head and the body on the responses. The generation of EOAEs is then discussed on the base of a first approximation model of the cochlea.
