Hi all, I hope this is the correct category to post this:
Basically I'm the owner of a relatively new BTO flat together with my wife and we got our keys mid last year and moved into our house in feb this year after renovation was done. We had cement screed floor done for the whole house (bedrooms/living room) except toilet and kitchen and this was done by HDB contractor (appealed successfully for cement screeding + top up).
Everything was going well for a few months until we were notified by our downstairs neighbor every few weeks that we are making 'a lot of noise' when all we did was walk from a bedroom to the kitchen, or generally inside the MBR. We were also told by our neighbor that we were slamming doors when this was not the case..
Our neighbor has came up several times over the few months we have been staying there to inform us (nicely) that we are disturbing their peace when all we have been doing is walk around.. so we finally arranged a day where one of us went downstairs to their house while one of us stayed upstairs to walk and hear for ourselves and true enough we have to admit it was pretty audible.. even when walking lightly (toes first and not heel first). Then we tried closing the toilet doors and this was also very audible for the unit downstairs. The worst part was when my neighbor also mentioned that he can hear when I put the toilet seat down.. and true enough when we tried putting the seat down (not slamming it down) we could hear a "clunk" from downstairs where it was very obvious that someone put the toilet seat down.
We were aghast at hearing this for ourselves, and my neighbor included as they went up to see and walk around for themselves when they realized we were not intentionally stomping our feet or slamming the doors.
I'm not sure if it is the combination of the cement screed + their false ceiling that is amplifying the noise so much.. I don't hear the same volume of noise from my neighbor upstairs except for the occasional dropping of items and I have never heard my upstairs neighbor walking excessively loud, closing a door or putting a toilet seat down.
The cement screed was done by HDB contractors so I don't know if there was anything that could have reduced the transmission of noise downwards to the downstairs unit. Their false ceiling is hollow (as are most) and might be amplifying the noise.. but I find it highly unreasonable that I can't even walk normally in my house without every step being heard by the unit downstairs.
I'm not sure what can be done at this stage.. even if we do raise this up with HDB, what are the physical steps that can be taken to reduce this noise transmission? I don't have a false ceiling installed so I'm not sure if having one actually amplifies noises from upstairs, does anyone have any experiences regarding excessive noises coming from your upstairs neighbors with/without false ceiling installed in your home?
