The sound conduction between the 2 apartments is horrible. It needs to have something done so the plan has a few facets.
We will install clips and rails that separate the drywall from the ceiling joists with little rubber blocks. This is supposed to diminish vibration travelling between floors and cut down on sound. I hope it works as they're very expensive. We'll do 2 layers of drywall too
Another aspect is to install glass fibre insulation between the joists to cut down on different frequencies. This is a horrible job as the fibre gets out and into clothes, skin and lungs. Not nice. I spent an itchy 4 hours installing this stuff last night. Breathing mask and glasses help with the other symptoms
It has helped slightly. Conversation is less audible downstairs, but the dog thumping on the ground when he scratches is still loud. Let's hope the drywall and clips do their job.
