My upstairs neighbour everyday doing weight lifting and throwing the bar bells on the floor. When I complained to the security guard, they checked and told me no noise. It is very hard to catch the culprit, don't know which unit above mine. Checked with the unit directly above mine and she said its not her. It is annoying because the noise only lasted for about 3 seconds and very loud. Interval about 35mins-1 hr and 7- 8 times per session . Crazy neighbour doing it from 11PM to 3 AM. Sometimes in the early morning bout 630AM. Sometimes in the afternoon, or evening. Complained to condo management but nothing being done. Don't know what else can do...every night can't sleep well caused by the sudden loud noise. Help!

Talked to the upstair neighbour, she doesn't stay there but occasionally come to check on her unit.. she also heard the sound and its the floor above her..means 2 floors above mine..if that the case, then its super loud that I can hear it 2 floors below..That unit is rented out..
The guard that went to check even said it could be the floor below mine..but what I heard seems to be from above..unless the whole building vibrates to that sound..

Argghh so frustrating, I slept at 4AM yesterday...I jot down the time it happens 11:15PM, 11:58PM, 12:33AM, 1:11AM, 1:49 AM, 2:27AM, 3:06 AM
Then i noticed the pattern.....after 12:33AM, the interval is 38 mins, when i called the guard at 3:06AM to check..it was too late...we waited for the next interval..but that was the last for that nite.. so geram!

The sound of something dropping on the floor for 2-3 sec..dont think it's water pipe...the building is quite new
the sound is like the olympic weight lifter holding the bar bell for few sec and then throw it on the floor..except that the floor is padded with rubber or something to absorb to loud metal sound hitting the floor...

she doesnt stay there..so , its not that big impact to her...

easy for you because u know which unit causing it..sometimes ppl do renovation very loud drilling sound, we also not sure where the sound come from whether its from right ,left, top right, top left or other units..
now i need to find out the culprit..talking to the security guard also no use...u call them, they go and check ..no sound..that's it..the most they can do is to wait for 10-15 mins outside the suspected unit..they also scared the owner scold them..

ohhh...actually i m staying 7 floor below the water tank..so today i went up to the water tank room and listen for the sound..i can hear the sound from outside the room but its not as loud from inside my unit..
i told the mgmt office maybe its from the break tank room but they said no one from other floors complain..zzzz..really wtf this management..i even recorded the sound and let them hear, they said will send a guard to stand outside the room to record the time of the sound...
btw, my condo is only 2 year old...if its really the pipe knocking sound..what can they do?

yeah, dont think someone could be so crazy throwing heavy objects every 38 minutes interval..Now the unit below me also can hear..although he doesnt stay there.. midnite also very loud..really dunno apa rosak..i stood outside the pump room listened to the sound, its not as loud more like echo..but at my unit its freaking loud..
