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.
