Digital Hearing

Digital hearing aids are becoming more and more common everyday because the required circuitry is much smaller than similar analogue models, and is getting smaller everyday. Some people even wear a type of hearing aid in their ear everyday even though they do not have any hearing loss or impairment. They wear them, usually in one ear, for the purpose of connecting hands free with a communication device such as a cell phone.

Digital hearing aids are also becoming completely wireless, so adjustments made to one hearing aid are sent to the other aid in the other ear. The microphone can also be wirelessly connected to the speakers that are in each ear. The size of the aid is limited by the battery which has to power the speaker, but they can be much smaller than typical models. As more people put digital devices in their ears, hearing aids are becoming more accepted and less noticed.

FM systems can be employed with digital hearing aids as well. A special microphone can be given to a speaker, whether it is at a religious service or just at a restaurant or mall, which can have a direct FM connection to the hearing aid. This eliminates background noise and the difficulty of listening to voices over large areas. Active listening systems can transmit sounds made on stage directly to the hearing impaired.
