Loops - Induction loops in the home - FAQs

Hello Mary, I am a teacher of Lipreading and I use an Echo megaloop in my classes with great success. However one of my members has the same system at home and is insisting that it is faulty, saying the sound is "echoey". He brought it to the class for me to try and as a hearing aid user, I tried it and found no fault with it. He is very insistent and I am at a loss as to how to advise him. He says he has sent it back to the manufacturer but told there is nothing wrong with it. He is raising this matter every week, clearly unhappy.
Do you have any suggestions as to how I can help this man - maybe it is his hearing aid which is faulty? Or the controls need adjusting on the megaloop?
I would welcome your advice, he is most persistent. Thank you. Linda.
