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.
