Thx ladies for those responses. I think the music at the gym needs to change. Appreciate the tip on measuring the volume at each bike with the device. Makes a lot of sense. People can be so grumpy about things. Don't think they realize the potential. Even when you try to tell them. Things will just "happen to someone else", not them. I bought the foam ear plugs at the drug store. They will be going in my gym bag for spin class. Our hearing as cyclists is very important for safety. I hate the thought that I might have loss. You see the ENT doc first, then a diff appt for the audio girl to test the ears. Takes a bit to get in. Try to post back on that. Any more thoughts welcomed.
