FM listening systems
The speech signal can be transmitted through a high frequency FM band to provide better signal clarity to the hearing impaired. FM hearing systems can be linked to a hearing aid or cochlear implant for better hearing in school, noisy situations etc. These systems provide better clarity to the speech signals by improving the signal to noise ratio. The approved FM bands vary from country to country. FM hearing systems consists of a transmitter and a receiver. The transmitter is worn by the speaker and the receiver is attached to the hearing aid or cochlear implant.
