Analog technology is the oldest, simplest and most inferior technology in the manufacture of hearing aids, which enhances both speech and environment sounds. Low sounds are amplified and made strong enough to be heard, while loud sounds are amplified to a lesser degree, so the user of the hearing aid is protected from them. Many of the advanced features offered by digital technology are not available in analog devices.
With the advent of digital technology, patients enjoyed an improvement in sound quality. The digital devices are embedded with computer chips so that the sound can be processed at the frequencies that correspond to the given hearing loss, thus enabling the Hearing Aid Dispenser to adjust the hearing aid to the patient’s needs, achieving a result very close to natural hearing.
Nanotechnology is the latest scientific approach that takes place at a molecular level to further enhance the experience with hearing aids and offer more functions than simple digital technology has provided us with. Hearing aids that incorporate nanotechnology can almost eliminate the irritating aspects of old devices like the so-called “whistling”. Additional advantages of this technology are the smooth transition between different environments, improved speech comprehension, automatic activation and the elimination of the need for manual adjustments.
Finally, nanotechnology enables users to enjoy their hearing experience by being fully water-proof thanks to nano-coating on the exterior surface of the device, an innovation that is particularly important since the major reason for the erosion of hearing aids is humidity.
