I recently bought a 1st floor unit of 2-family condo, knowing 15-yr-old twins live above me, so as part of the renovation, I ripped the ceiling, place insulations and sound board + sheet rocks. Now the renovation is done, I moved in, and I am suffering from their constant stomping noise from the unit above. I don't hear talking or TV noise (thanks to the sound boards) but unfortunately it doesn't dampen the impact noise (particularly footsteps). They are heavy footed and I believe they have hardwood floor with no carpet. They wake me up 5:30 every morning.
By reading other posting, it seems like I should have installed resilient ceiling but I didn't know at that time. Is there any way to dampen the impact noise without taking down the brand new ceiling? The building is 90 years old and there is a lot of squeaking noise too.
Any advise is appreciated.
