[The behaviour of the post-stimulatory acoustic response trigger threshold during experiments and with noise workers (author's transl)].
The findings on impedance jump responses after experimental and professional exposure to noise are presented and discussed. It can be shown that the trigger threshold of the impedance jump is raised only slightly by the development of a temporary shift of the threshold of audibility (TTS). By sealing the acoustic duct with ear-plugs (made of cotton and wax) however, the trigger threshold shifts by the same amount in decibel which originated through the sound attenuation itself. Furthermore, the impedance jump can be triggered more and more rarely with increasing exposure to noise during the working years under noise of noise workers. This can be explained by the additional increasing degeneration of the ganglion cells and the auditory nerve.
