[Continuous stapedius reflex registration in low and high intensive levels (author's transl)].
To study the whole dynamic range of the stapedius reflex the intensity of the soundstimulus with fixed frequency is continuously changed from 70 to 115 dB. Thus we get results concerning the real reflex eleciting intensity level. the gradient caused by continuous intensity change and a possible limit of contraction. To investigate time resolution phenomenons the stimulating signal is pulsated in a second trial. We used this method of stapedius reflex registration with 48 normal ears and a group of patients with sensorineural hearing loss. The results and the diagnostic possibilities of this method are discussed.
