Residence is an apartment. Common wall with the "neighbor" seperates my living room with their kitchen. The "neighbor" seems to take delight in ensuring I hear each and every time they close their cupboard doors. The landlord's suggestion and action was to install rubber cushions to absorb the cracking sound of two pieces of wood coming together, doesn't work ;-( I relize that soundproofing is out of the question. Is there any way of a least deadening the sharp cracks to a dull thud? I thought maybe plywood covered with acoustical tiles may help, but wanted to check with the pro's before wasting time, effort, and resources.
I also heard of a foam material that can be sprayed in between the studs of a wall. If so, would you include a product name and manufacturer if the foam is a viable option?
