To change

If the case is the neighbors, you will have to talk to them and convince them to change the floor. An excellent option could be a "floating technology". However, this is not always possible, since relations with neighbors may not be the best. Then there is only one way out — to carry out high -quality sound insulation of your ceiling. However, such an expensive event will still not be able to remove all extraneous sounds by 100%. It is much better to overpay a little and install the soundproofing of the ceiling, which, although it conceals a certain space, but provides an excellent effect.
