ABSTRACT OF THE DISCLOSURE In hearing aids to be worn in the ear there arises the problem of the fouling of the sound emergence opening by ear wax. The hitherto known ear wax-protective plates do not meet all the demands to be made on them. There is proposed an ear wax-protec- tive device which consists of a yoke joined with the auditory passage part of the hearing aid, which, however, makes possible an easy removal of accumulating ear wax, without damage to the sensitive electrical components present inside the hearing aid.
