Abstract (en)
[origin: EP0993232A2] This is referred to patients with partial or total loss of hearing of the one ear and somehow good or excellent condition of the other ear. The essential difference from the ordinary dullness earphones of optic glasses type, or any other type or system, is the addition of a second microphone in the altitude of the ear with necrosis. By the use of this device the patient may perceive low intensity sounds even whistles as well as the sound of a telephone earphone from the side and close to the ear with necrosis. This device consists of: 1. Microphone: mini condensing microphone (ordinary) 2. Pre-amplifier of acoustic frequencies (ordinary) 3. Earphone: (or sound vibrations system for incitement through the cranial bones, of the acoustic nerve), for the healthy ear (ordinary). 4. Batteries and switch on-off (ordinary) 5. Adjuster for voice volume (ordinary).
