True, although distance makes a difference, and the farther away from the loop you are, the more the sound will deteriorate.
True. But you must watch out for sources of interference. Just as too much light causes interference with infrared because it is using light to transmit the signal, anything that creates EMF can cause interference with induction loops...and telecoils. This includes computer monitors, lights, appliances, and power lines, to name only a few.
False. Ok-trick question. If you have a telecoil in your hearing aid, you do not need a separate receiver. The telecoil itself is the receiver. If you do not have a telecoil or do not use a hearing aid, you will need a separate receiver.
True. You must have a hearing aid with a telecoil to use this system or have a separate receiver coupled to headphones if you do not have T-coils (this is a less common application).
False. The EMF will pass through walls creating spillover and interference, just as the EMF from the power lines pass through the walls of a house. In addition, others may inadvertently pick up the signal. For example, if a telephone is on the wall outside a room that is using an induction loop, and a hearing-impaired user goes to the phone and switches his hearing aid to ‘T’, he may very well pick up what is going on in the room instead of what is coming across the phone, as the phone’s electromagnetic signal will be much weaker than that from the room’s loop.
True. The user with a T-coil simply walks into the looped area and switches the hearing aid to T. No other equipment is needed.
