15.What is the F.M of AIDs
Answers
FM Systems are wireless assistive hearing devices that enhance the use of hearing aids, cochlear implants and also assist people who are hard of hearing but do not wear hearing aids, in particular over distance and in noisy environments.
They enable sound to be picked up closer to a speaker, sound source or connected directly to the sound source and transmitted to the individual providing greater clarity of speech/sound and a reduction in background noise.
FM System is the generic name or term that has been given to Radio Aids.
FM is the abbreviation for Frequency Modulation.
Frequency Modulation is a wireless transmission method used to transmit the sound.
The main advantage for Hearing Aid wearers is that FM transmission is resilient to noise and interference helping to preserve the quality and clarity of the sound transmitted.
Some companies are also using digital transmission but the products are still “labelled” as FM Systems.
The abbreviation MHz means Mega Hertz (Mega = million, Hertz is the unit of frequency).
