Can I do anything about the noise level of my neighbor above me?

In most cases, a tenant is guaranteed what is called "quiet enjoyment" of the unit.  If the tenant above you changed the flooring, and now there is more noise, you are entitled to complain to the landlord that he is not providing "quiet enjoyment" and that the flooring must be fixed so that it is more soundproof.  If this is not a rental situation, but instead one in which someone owns the unit abouve you, then you will have to take your case up with the condo association if they approved the renovations and change in the flooring.
