Abstract
For hearing aids to be worn in the ear initially the measurements of the inner space of the ear are determined by a laser apparatus and the measurement are stored in a computer. The computer controls a milling cutter on which a blank consisting of plastic material into which all necessary components, such as electronic amplifier and sound transducer have been molded is shaped by means of a milling operation to provide a shape corresponding precisely to the inner space of the ear. The method eliminates the time consuming work for the production of a mold and the purchaser can obtain immediately a precisely fitting hearing aid.
Claims6
A method of producing a hearing aid which is worn in the ear and includes an amplifier and a sound transducer built into a body member which is made to conform to the inner space of a respective ear, comprising the steps of initially taking measurements of the inner space of the ear up to the eardrum for use in producing an individual shape of the body member corresponding with the measurements of the inner space of the ear, storing the measurements in an electronic memory, providing a body member blank of plastic material and having an electronic amplifier and a sound transducer molded therewithin, and controlling a cutting operation of a cutting machine based upon the stored measurements to cut an outer surface of the body member blank to provide a desired shaped individual body member having an outer surface shape that corresponds with the ear inner space measurements.
