Late at night as things quiet down. That is when mine is most noticeable. I think I can sense when my BP is elevated by the ringing as well. From what I am reading, I don't have anything to complain about. Just a bit annoying. I do wear ear protection everytime I run chain saws, mowers, trimmers, etc. Occasionally jump in a skid loader without it but generally just short time periods like to load a scoop or two of mulch or salt. If running on a job site I bring ear plugs or muffs.
I blame my wife. My ears are protected when working. It is getting yelled at by her that has caused my hearing loss.
. (she hates that joke. Probably because there is some truth to it. Her whole family is loud.)
