How to stop noise from upstairs unit.
I own a duplex that we have turned into a triplex. We live in the basement unit. We built this unit from scratch, it was a large finished empty basement. We insulated the ceiling to help with noise but it hasn't done much at all. We are in the process of updating the upstairs unit. My husband has gutted it. I'm planning on floating vinyl plank throughout the entire unit, with the exception of tile in the bathroom. What underlayment should I use to reduce noise. Right now with an empty unit and no flooring I can hear every step and the sound of talking. I've researched but I can't find much good info. Please help. thanks - Jessica
