Do you think the neighbour downstairs is just inventing his
frustrations?
He and his family are at their wits end. Conclusion, there must
be noise.
They say it from your flat upstairs, you say it is not.
They are furious enough to stomp upstairs at 1.30am., and you think
they are insane. There must be something there.
Noise travels. Vibrations are transmitted. Shock waves are
thrown about.
Is there a main road beside your condo? Does heavy vehicles
passes there once in a while. Are there construction going on the
vicinity? These need to be looked into because the neighbour below
is definitely hearing the thump from his ceiling, and assume you
are causing it. It is possible the thump is from somewhere else,
transmitted through the reinforced concrete (RC) to that spot in
the ceiling.
Town councils have records of cases where the residents
complain of upstairs banging the floor or dragging furniture, but
upstairs is vacant, or away on holiday.
Some neighbours can sit down together and discuss, some just
handle themselves very badly. For the later, need third party
to mediate.
Agree. When you are asleep or hardly awake at night, it's hard
to know where the noise came from.
