How Does An Infrared Hearing System Work?

 

The system works in the same way as a remote control on a video or television, i.e. an emitter (the remote handset) sends out an invisible beam of infrared light which individual receivers (the TV), convert into sound via built-in headphones.

The Lord Chancellor's department recommends this type of equipment for use in courts due to the security aspect. The signal cannot be heard outside the room unlike a loop that can sometimes be heard several meters outside a room due to overspill. Larger emitters are used in court rooms and theatres. As the size of the room and the amount of people wishing to hear increases, additional emitters and receivers will be required.

 

Advantages of the Infrared System

 

  1. There is no loop with an infrared system - this is of particular benefit from an installation aspect where the fabric of the building, a church for example, cannot have cable attached or visible.
  2. Infrared transmissions will not permeate walls, ceilings, or floors. This means that each room has total privacy from any other room.
  3. Since infrared systems are not hampered by multiple frequency problems, a person wearing an infrared receiver in one room can move to another room and use the same receiver unit without switching frequencies or units entirely. You may be familiar with some museum or tour facilities PAIRS 80 casethat use infrared systems. As you move from room to room, you automatically hear the presentation specific to the room you are in.
  4. Infrared systems can also be set-up to provide stereo sound. This is especially beneficial in theatre, auditorium facilities, lecture halls or presentation rooms where high quality audio is being produced as a part of a video tape or laser disc.
  5. Infrared headsets have the receiver unit built into the headset, therefore no wire or connector failures can occur.

 

 

 

In What Situations Are Infrared Hearing Systems Most Commonly Used?

 

Induction loop systems can be installed in locations such as churches, theatres, public halls and auditoriums, schools, lecture halls, residential homes, cinemas, service counter windows, offices,airports, train stations, cars and homes. Due to overspill issues, loop systems are not recommended for situations where privacy is desired, for example, in court rooms.
