Abstract
A device for electromechanical stimulation and testing of hearing in which an electromechanical transducer transmits audiologic signals as mechanical deflections via a coupling element from the outside, noninvasively through the external auditory canal, by direct mechanical coupling with the manubrium of the malleus to the ossicular chain. In preferred embodiments, by suitable selection of the transducer principle disruptive magnetic stray fields and acoustic stimulation by sound transmission to the contralateral ear, which is not being examined, are prevented.
