Free Damage to your ears

I have regularly asked the attendants at this gym to turn down the music a bit, but as soon as I get upstairs its turned full blast again. I feel as if I'm in a rave club. The whinning, screaming, t******* music is absolutely awful. Why do we have to be subject to all this ear damage ?? I have spoken to a number of people here who agree with me, but also know that no one at this gym takes any notice of the complaints. Should this continue I will have to resign my membership here.
