FM Systems (Assistive listening devices)

FM Systems are solutions that give people with hearing loss the same...
opportunities for communication as people with normal hearing. But in noisy environments and other difficult listening situations, hearing aid users may receive additional benefit from using a dedicated FM radio communication system.

A new and improved FM system

The FM System gives both children and adults with impaired...
hearing optimum opportunities for hearing and understanding speech when they are in noisy environments with poor acoustics. The FM System makes everyday communication easier.

The FM System consists of two parts:

  • A microphone with a built-in FM transmitter transmits the sound signal as a radio
    signal to one or more receivers
  • FM receiver that is connected to the hearing aid via a new audio shoe, featuring the completely new slide-on system.

The physical separation of the microphone and the receiver allows the hearing aid user to understand speech in noisy environments and at distances of up to 30 meters. Setting the microphone into directional mode allows the user to hear speech clearly at a distance of several meters, including in places with a high amount of noise and poor acoustics.

Telephones and loop systems

If you have an acute hearing loss, you could benefit by using...

different types of special technical aids.

Below are some examples:

  • Loop systems for TV or radio
  • FM and infrared systems
  • Telecommunication equipment
  • Warning device

Loop systems for TV, stereo or radio

If you use a hearing aid with a telecoil, a loop system will enable...
you to hear a television or a radio from almost anywhere. Basically, a small microphone is placed near the television, stereo or radio. It picks up the sound and sends it to an amplifier and then on to the loop.

Some public buildings such as cinemas and churches are equipped with loops. A counter loop is a special loop, which can, for example, be fitted at banks and ticket offices. These small loops cover the immediate area close to the counter.

FM and infrared systems

An FM system is a two-component system that consists of a microphone...
and transmitter which are worn by the speaker, and a receiver and an earpiece which are worn by the listener. The signal is transmitted via FM radio waves. This is a good solution where, for example, lectures or public meetings are to be held.

An infrared system works more or less like the FM system. But here, the signal is transmitted via infrared light waves.

If you have a hearing loss and sit close to a television or a radio, he/she can also use an ordinary headset or neck loop.

Telecommunication equipment

If you find it difficult to hear what people are saying on the telephone...
there are several types of specialized telephones on the market that can assist you.

Telephones with amplifiers can be one solution.

Some telephones can also be supplied with an additional earpiece – sometimes called a watch receiver. This makes it possible for you to listen with both ears. It is also possible to get an extension tone caller.

If you suffer from acute hearing loss, a text-phone is probably the answer. With a text-phone you can type text instead of talking. If you would like to communicate with a person who is using a normal phone you will, however, need to use a telephone company that can provide on-line speech to text and/or text to speech translation. For further information, contact your telephone company.

Warning devices

Most alarms and warning devices use noise to draw attention...
But standard devices will only be of limited use if you suffer from hearing loss. It is possible to get alarm clocks with flashing lights or vibrating pads which can be placed inside your pillow.

Doorbells can also be connected to flashing lights. You could also have extra doorbells installed at different places around your home.

Smoke alarms use a high-pitched signal which may or may not alert you in time. Today, special smoke alarms have been developed that use both visual and vibratory stimuli to alert you.
