Getting old is not nice Arthur.With me high frequencies are hard to hear, but low frequencies too.It sounds to me as though people are talking through cotton wool. Doesn't bother me too much as some people are not worth listening to, but I find the worst feature is my hearing is non directional. Crossing a road if I hear a vehicle, I can't tell if it is left or right, and on the towpath I may hear a bike approaching, but have to look around to see if it is behind.
Was told when I was young that there are advantages in growing old, but now that I am old, I'm damned if I can see any!
