Tenants in our apartment disturbing our peace.

I live in an apartment in Pune, Maharashtra. Recently one of the owners in our apartment have rented a flat to a family of 10people, in which 3 kids and 2 men and 5 women are living in that flat above us, there is even an mentally challenged adult living with them. We don't have any problem if they live peacefully here, but the keep on disturbing us but banging voices on our roof as they live above us. Its been 4 to 5 months they are doing the same, and even their owner doesn't care about the issue. Owner always blame us for everything if we complaint her about the situation we are facing, and tenants threatens us by saying "Do whatever you want, things will remain as it is", they even rudely insulted my mother when she went to ask them stop banging the floor much, which made me angry a lot as she is my mother and elder then them, but as a guy i cant interfere or question these females, they might even get me in trouble for misbehaving with them. So i want all you respected professionals to help me solving this problem without voilence.
