My work place is sooo loud i was wondering if this is workplace hazard?

I work at an amusement park as a ..... cleaner so basically I walk around all day cleaning garbage. The problem is that the park start doing light show near the closing time. The music is very loud it's to the point that my ears is aching and my head is pounding. I went inside bathroom and I still can hear it. The show goes on for 15 minutes. Is this bad for my ears. Should I file complaint or tell my employer? I really want to stop this. The speakers are really loud in general so we are already expose to loud sound from rides and people. Thx
