Unbearable noise

The following Problem adds to our everyday frustration.please suggest how to proceed.also suggest the approx procedural costs which will be inculcated in this entire process 1.Unbearable noise from 6th floor resident. They have 4-8 year old children who play outdoor game ,and keep running in passage area throughout the day.This creates a lot of unbearable thumping like noise.They also create noise after 10.00pm which does not allow us to sleep.Another type of noise is dragging of jumping activities .Even after repeated requests for 3 months they have not stopped playing.They have also been arrogant towards us and challenged us to stop them.Do we have an advantage over them? Also collecting proof and evidence is difficult as the voice recorder is not able to absorb thumping noise clearly Is calling the police an option? but calling them at the right time would again be difficult as noise may or may not occur at that time. Is there any other way we can prove them wrong? They claim that it is their home and they can do anything. Are they right? Please Help Regards
