I spent several days with two of my brothers, a cousin and some friends fishing in the Ozarks in Arkansas last week. Several times, one of the guys would tell me, "Your speaking too softly, speak up!" I realized that I was talking at a normal volume and the hearing aids were working great. I had to concentrate to speak loud enough to have a conversation.
The hearing aid volume did change several times in the boat and outside in the wind as noise level changed. I heard birds, frogs and other critters than I never heard on my previous trips. I also heard the fly line going through the rod guides when I made a cast. Interesting.
I suspect I will not be the only brother in my family wearing hearing aids in few years.
