Patent

CA 2485475

The invention essentially consists of a new type of hearing aids in which all components, including the loudspeakers, will be located externally to the ears. This will permit the use of relatively large size components, which will ensure that sounds are captured, amplified and delivered to the hearing membranes with a sufficiently high level of energy and fidelity in the entire frequency spectrum of human speech. For instance, the use of large size loudspeakers is essential to the reproduction of sound particularly at the lower frequency range whose wavelength exceeds the physical size of the miniature loudspeakers used in existing hearing aids that are either inserted inside or located behind the users' ears. The external hearing aids will also use existing technologically advanced microphone arrows that when combined with sophisticated electronic circuitry, already available in the market, will permit achieving good sound reception and valuable noise suppression.
