Abstract
A device for electromechanical stimulation and testing of hearing having an electromechanical transducer for producing mechanical stimulation vibrations. The mechanical stimulation vibrations from the electromechanical transducer are non-invasively transmitted through an external auditory canal to at least approximately the center of the tympanic membrane (the umbo) and thus to the manubrium mallei of the ossicular chain. An impedance measuring system measures the mechanical impedance of a biological load structure which is coupled to the transducer.
