hearing app for hard of hearing or deaf

here is the first hearing aid concept that I in theory approve of, only the primax. Shame this hearing aid company a large one is only now understanding hearing.

This in theory is the best concept I have seen. I was going to file for a patent on array processing hearing about 18 years ago, but found a professor at Stanford who had been involved in array processing for I think sonar beat me by a year or two. But now I believe this is the first real product using array processing to hit the consumer market. I have not tried one because of the costs but will someday.
