Deafness is a sensory disorder which affects a sizeable number of people all over the globe. The causes for deafness may be inherited or acquired later in life due to certain diseases, wear and tear or due to traumatic experience. The intensity of deafness of the ear may not be absolute and the afflicted person may suffer from partial hearing impairment. To rectify such a deficit, a hearing aid is used to enable the user to hear all frequencies of sound. A hearing aid is an electroacoustic device consisting of a small in-built microphone, amplifier and a speaker.

It has been estimated that only one out of five deaf people actually make proper use of hearing aids. The reasons as to why many people don’t favor hearing aids are that they have proven to be ineffective in noisy surroundings, in large open spaces like museums and large halls. Also they emit unpleasant buzzing noise when other electronic gadgets are brought close to the hearing aid due to interference of the magnetic fields. To put an end to all these persistent problems, the world of hearing aids embraced wireless remote technology to develop wireless hearing aids.
Wireless hearing aids receive sounds by means of a wireless remote controlled device. To minimize the noise from surroundings, a microphone is placed close to the mouth of the talker and the sound is carried to the listener by means of a wireless link by modulating the frequency of the sound. The efficacy of wireless hearing aids is amply proved by the large margin of improvement of the signal-to-noise ratio, which has not been achieved by other technologies like digital noise managers and directional microphones. Wireless hearing aid technology is improving by leaps and bounds with several companies manufacturing wireless aids with in-built receivers and frequency hopping features.
Though there is a significant advantage given by wireless hearing aids, there are several other constraints which have halted the foray of wireless technology in the domain of hearing aids. One factor is that unless a microphone is worn by the talker, the listener cannot hear the other’s speech clearly. Also, wireless networks are susceptible to wireless interference causing defects in the output. Since the technology is quite recent, there is also the high cost factor which has not favored the growth of wireless hearing aid technology. However, research on this domain is being pursued actively and in near future, we might just find the right kind of hearing aid, thanks to wireless technology from Siemens hearing aids.
