General Hearing Instruments. Found them on Ebay for $400 a piece. Your used car salesman/audiologist will offer a slightly better option for $3000 a piece. These are very small behind the ear devices. They are programmed for high frequency loss. I wear one in my good ear. Do not listen to what they tell you about "filtering out unwanted sounds". The sounds you want to hear are voices. When you are in a crowded room it gets loud with voices. I second the idea of getting the medical issue resolved first. AN ear infection is how I lost my hearing. What was that you said?
