Assistive Listening Devices
An assistive listening device (ALD) is  type of device that can help you function better in your day-to-day communication situations. An ALD can be used with or without hearing aids to overcome the negative effects of distance, background noise, or poor room acoustics. So even though you have a hearing aid, ALDs can offer greater ease of hearing (and therefore reduced stress and fatigue) in many day-to-day communication situations.

Hearing aids + ALDs = Better listening and better communication!

Types of ALDS

Personal frequency modulation (FM) systems are like miniature radio stations operating on special frequencies. The personal FM system consists of a transmitter microphone used by the speaker and a receiver used by  the listener. The receiver transmits the sound to your hearing aid either through direct audio input or through a looped cord worn around your neck.

Personal FM systems are useful in a variety of situations such as listening to a travel guide or book review, in a classroom lecture, in a restaurant, in a sales meeting, or in a nursing homes or senior center.

FM systems are also used in theaters, places of worship, museums, public meeting places, corporate conference rooms, convention centers, and other large areas for gathering.   

Infrared systems are often used in the home with TV sets, but, like the FM system, they  can also be used in large settings like theaters.

Sound is transmitted using infrared light waves. The TV is set at a volume comfortable for family members. The infrared system transmitter transmits the TV signal to your receiver, which you can adjust to your desired volume. Thus, TV watching as a family becomes pleasurable for all. While it is not too loud for family members with normal hearing, the volume is just right for you because it is adjusted by you through your individual receiver.

Induction Loop Systems are most common in large group areas. They can also be purchased for individual use.An induction loop wire is permanently installed (perhaps under a carpet) and connects to a microphone used by a speaker. The person talking into the microphone creates a current in the wire which makes an electromagnetic field in the room. When you switch your hearing aid to the "T" (telecoil/telephone) setting, your hearing aid telecoil picks up the electromagnetic signal, and you can adjust its volume through your hearing aid.
