Party Wall Sound issues

[Truff105]

Evening. One for the sound proof specialists please.

I am trying to problem solve a sound proofing issue. 1930s semi detached house.

I wondered if it was possible for an assumed dot and dab plasterboard reno and then fixtures and fittings installed directly against/attached to a party wall/chimney alcoves (ie. Kitchen units or ply/mdf cupboards), could cause sound to transfer into an adjoining property (semi detached) through the party and flanking walls, and for effectively one house to hear worse noise than the other?

How does an effected house go about sound proofing if the sound issue is caused from one side? Or if indeed it is just a generally badly soundproofed party wall? I imagine party wall sound is a common issue but it seems complex to resolve.


Thanks

Sound travels through solids.
Water as example sound can travel miles.
So brick and wood sound travels through easily.
You can sound block your side with stud wall.
Acoustic resilient bars.
Double sound blocking plasterboard but pack edges so it don't touch sides.
Fill gap around edges with mastic.
Pull packets and fill with mastic.
The plasterboard is now floating so sounds can't travel through.
You still have the floor and ceiling to sound block.
That's the problem with sound proofing, It's all or nothing.
Not really possible to reduce noise as it can get through if you don't sound proff properly.
Maybe the renovations put cabinets and screws in wall and that's transfering sound now

Had a thirties property in the past , sound transfer was never a problem , what issues are you having .

Foxhole, The main sound issues are as follows.

Flanking wall and Party wall noise. I can hear my neighbours in my front room when they are in their kitchen at the back of the houses. I just wondered if screwing kitchen cabinets and building mdf cupboards in chimney alcoves and into the party wall (not our side), could cause sound to be worse one side of the wall to the other? And then, what can I actually do to soundproof.

What sort of floors do you have

What sort of floors do you have

A mix. Suspended floors majority to party wall boundary and flanks. Solid in the little outdoor section that we extended to bring inside.

If you don't have floor coverings sound can travel and seem to be amplified by suspened floors.
