This is a tough issue to litigate. Your county likely has an ordinance regarding sound and a certain decibel level will be considered nuisance. You can always call for law enforcement to investigate but that may only be helpful if the noise continues long enough for them to arrive and note the noise. If the noise does not reach a certain level, it is not actionable. They'll probably ask the neighbor to keep it down, though. Another option would be to consult with your condo association as there are likely rules/regulations for the premises and they can intercede for members. It is a subject that certainly requires some diplomacy, as your neighbor may not be going anywhere for a long time?
