31 weeks - loud DJ music at party?

So I'm going to a family party next Saturday, and will be 31 weeks pregnant by then.

I'm a little concerned that the loud music played by the DJ could be harmful to my baby's ears? I've read that excessive noise should be avoided during pregnancy, and although I have a barking Labrador and am around day to day noises every day, I'm concerned that such a loud noise could be harmful? I don't want to be a miserable pregnant woman who sits in the corner and leaves early... Anybody any idea as to whether I'll be okay to be around it for a good few hours?
