After much nagging from the wife and frustration in asking people to repeat what they just said to me, I made the trip to the audiologist for the hearing test. It seems that my high frequency capability is just about gone. I can't hear watch alarms, birds or high pitched female voices, especially those fast talking teenagers who work in fast food restaurants.
I was wondering how many others on the forum are wearing hearing aids. Obviously, I will not wear these while riding, since I must insert the foam plugs.
