That was to treat the acoustics of the room and will have little effect
on sound transmission in/out of it, especially at LF. For that you need
mass - lots of it.

Righto. The building looks very much like a CLASP style of construction, so
I suspect the best bet will be to give the neighbours my number and ask them
to ring me if it's annoying them. Having been present for the demolition of
CLASP buildings, I don't have much hope of listening to music at a decent
volume.
