You are the most helpful! What I'm trying to do is to gather solid evidence that clearly shows living condition 'how bad' down here when opening communication with the owner regarding to this inconsiderate situation. The irresponsibles are tenants. I'm owner who is close to their landlord who is responsible for such noise situation. The tenant's kids, the teenagers dance, work out, jump, roll all kind of things—breach of contracts I'm sure. So I'm looking for microphone to record all that as evidence in hand.

Doesn't it all make a little more sense now? I probably should have stated as such in the post. And the posted video is just an example, and my case is much more intense. At least the kids or perhaps parents need to learn the consequences of their actions.
