never had it, or could hear it until about three years ago. now, if the decible level in the lounge room exceeds a certain level (family tea nights, upwards of 8 people), i can't sit in the same room. it's unfair of me to ask them to be quiet, so i cook for them, then i go to the office.
in the car, i have to ask for quiet. which for my wife is hard to do
at work, in the workshop, if more than one grinder is going, i HAVE to wear ear plugs. and that is more than 20 feet away from the grinders.
water from the shower stall hitting the tiles hurts my ears.
and our staffies bark... **** me dead.
on a normal day, in a quiet house, i sit on average, a 4. but, it's all dependent on the surroundings. (it never bothers me while sleeping, as the wife always is watching a show, but even then i have to ask her to turn it down quite often.)
