Induction Loops provide a amplified sound to person using either a appropriate hearing aid or Induction Loop Head Set. They work via a loop of cable which runs around the area to be covered, this is connected to a Loop Amplifier. 

Please Note. While it sounds very simple in theory, in practice it is far more difficult, particularly for a large room.  To ensure both a even coverage across the room and to prevent interference with either the loop system or other audio equipment.

Induction Loops are divided into two basic types.

Personal Loop Systems.

Theses are used typically  in Bank's, Post Offices, Council and Benefits Offices, etc. They provide a localized loop system or even a induction pad which radiates sound across a small area.

The purpose of these systems is to allow improved sound in a intimate one to one interview environment. The microphone is usually a small counter top microphone or more commonly as part of a local, Public Address system.

This benefits persons with hearing difficulty who do not have a hearing aid, or general users. Often the above environments have a glass screen separating either sides of a counter. The local PA system helps overcome these difficulties.

Systems now exist that can operate side by side in multi counter set ups.

Room or Area Loop Systems.

These systems are used in Theatres, Concert Halls, Churches and general Public Gathering Areas. They allow multiple users to pick up the sound within the room or area they are standing/sitting in.

In certain venues they work as a stand alone system, without other Public Address equipment, however it is more common to find them as part of a larger general system.
