I'm currently living below the noisiest neighbor I have had in 30 years of living in apartments and condos. So I sympathize. But I'm not sure the landlord can evict anyone based on what you describe.
I would start by looking carefully at the lease, to see if there is anything about noise, right to peaceful use of the apartment, carpet requirements, "quiet hours," stuff like that. If they're violating the lease, then the landlord should take steps to remedy the situation.
I need to show proof to the condo management where I live in order for them to take action. I've been using the video camera on my smartphone to record the noise. I haven't sent anything to the condo management, though, because the primary problem is the dog running back and forth and back and forth and back and forth and back and forth across my ceiling, and a couple of noise complaints to the nighttime security guard have been somewhat successful in stopping that problem. And she's a renter with a long-term boyfriend, so I'm hoping she'll just decide to move out so she can live with him. (And when she does, I plan to sit on the front steps drinking champagne while they pack the moving truck...)
