to help me hear the TV with a volume that is reasonable for others who have good hearing my wife for example. I also use that
device at a meeting or presentation to help hear. My
hearing loss is all the high frequencies, about 8,000 hertz. That means I can hear well enough not to have a problem with moving around in public and driving a car, as examples. I can hear a train or turck coming as well as the next guy, but the sound of "spring peepers", no I don't hear them.
