That could end up being the judges suggestion. I know a condo situation where they suggested installing a faux ceiling for complaints about a tenant above. That's a considerable expense for the complainer and some sort of solution is usually expected from the noise causer as well.Could the neighbor could also put up acoustic panels or something to mitigate the sound?
It really depends on what the city bylaw states. Rarely is nothing done about a complaint, and rarely is it all on the complainer.
