She Sees To Hear - A Model shows just How in Conspicuous the new hearing aid is ... in fact if the hair is combed over the ear there is nothing to be seen. After two years research, Professor Schumann, Director of the Helmholtz institute of sound therapy, has ***** a hearing aid which fits into the ***** of spectacles. Built into the frame is an ***** microphone, Amplifier and hearing aid ... The Earpiece is contained in a tiny plastic case laid against the muscle of the ear and can Hardly be discerned. The frames also contain an Anode which can be recharged like a Battery. February 14, 1955. (Photo by Paul Popper, Paul Popper Ltd.).
