Nosiy neighbors

So I’m due in September and I’m really worried about my current living situation. My neighbors play loud rap music all day and late into the night almost every day.

I’m worried this will disturb me trying to rest and recover after delivery. Also make it hard to put baby down to bed. What can I do? I’ve contacted the landlord and police and the neighbors responded by coming over to intimidate us and blasting music even louder. There’s still almost a year left in the lease.
