Method and apparatus for detection of a reflection of the human stapedius muscle

The invention concerns a method of detecting a reflex of the human stapedius muscle (4), in particular for a hearing test. According to the method, the reflex is triggered by means of an acoustic signal, and the impedance or the variation in impedance brought about by means of the reflex at the eardrum (1) is measured by means of a further acoustic signal. The object of the invention is to further improve the stapedius reflex audiometry method so that it can be applied in practice. To that end, at least two chronologically successive or mutually overlapping substantially identical acoustic signals (11, 12) are used. The information concerning a possible impedance variation at the eardrum (1) is obtained by forming the difference between the acoustic characteristics produced and registered by the signals.
