Have you met anyone living in an old high-rise condo apartment building who replaced their carpets with hardwood flooring and then began complaining about the noise coming from the apartment below. Well they took up half the soundproofing when they removed the carpet. Those old high-rise apartments were built with carpets in mind. The builders planned for the carpeting to block sound (and they cut costs that way).
If the neighbors upstairs are going to put in hardwood floors they better expect to hear your TV.
