ReSound Future problem
I've had these hearing aids for a couple of months. On the first followup visit I explained that on one or two occasions my hearing aid (one or the other) seemed to transfer a single tone or note from it's source directly into one or the other of my hearing aids, and at high amplification. It was the first the dispenser had heard of such a problem and had no answer for it. It has occurred many times since, especially while watching HDTV. It happens when, for instance, a musical instrument is being played. In one striking case, a movie scene in which a person rang a buzzer to gain access to an apartment complex, the instant he put his finger on the buzzer the sound emanated loudly from my hearing aid! It didn't seem to come from the TV speakers at all. A hearing aid blogger has said the is a problem called "entrainment," which current hearing aid technology has supposedly resolved. I will bring this up with the Costco dispenser on my next visit.
