I experience interference from motion detectors connected to light
and security devices. It especially annoying when I have to sit in my
supervisor's office and my hearing aids do not work.
I called Oticon Hearing Aids about my experience with the hearing
aids I bought from them and they called it supersonic interference. They
fix the problem by adding adjustments but I still have to pay for it.
At a cost of $125 per hearing aid I felt like that was a rip off.

They are just now getting around to admitting the problem and making the
corrections on the newer model hearing aids.

On the positive side, I have been very pleased with my Oticon hearing
I just wished I could get rid of this interference.
