This is all fine, except our apartment is on the 6th floor, and below us is 5 floors of CARPARK. So, thinking that the by-law was a bit unreasonable to be applied to our apartment, we took it to an AGM.
You’re assuming that noise created at the floor can only travel downwards.
My recent experience is that concrete slabs are very, very good at transmitting noise sideways.
There’s a couple of units in our 8-pack being renovated at the moment. A few weekends ago there was lots of banging and hammering and it sounded like it was coming from the unit directly above me. Given that unit is tenanted whatever they were doing was inappropriate so after nearly an hour I charged out ready to give them a “serve”. Fortunately on my way I discovered the noise was in fact coming from a unit two positions along the building.
So noise transferred to the building structure can quite easily travel via structural elements of the building.
