How to measure / interpret volume attenuation to neighbors

Interesting advice gathered here is that it is not necessarily energy delivered to the air which annoys neighbor flats, but the conductiveness of the physical links. So the practical first step is to disconnect woofer cabinets from the room; by suspension, springs, sorbothane, etc.

Yes, this would be advisable. Perhaps you can get a hall-pass from your neighbors for certain days/hours for sub connection!

All walls are not alike – a look at STC
STC is the acronym for Sound Transmission Class.
The STC rating for drywall on hollow wood studs is about 33 decibels...

Also remember to keep the bed-posts away from the common walls.

While this is said to be pretty effective anecdotally, in general cabinets shouldn't be moving very much at all compared to the cones, so even if they are totally isolated from the floors / walls, you still have quite a bit of bass in the air that can't be dealt with so simply.
