Soundproofing Apartment Wall

SpeedySproule

Hey,

First time poster, I recently purchased an apartment in Galway city. I've done alot of work on the place but my only problem now is noise level. My neighbor next door has a kid that is crying non-stop and in general you can hear most noise from the bedroom area. I am not as concerned about any other areas in the place.

The dividing wall I believe is only single block and has not been filled. Its a solid wall but still doesn't block noise very well. To give a better understanding of the layout, there is nothing above me as its the patio for the apartment above. The bedroom is the last room before the back garden and the next room over is the bathroom.

I am looking for advice on any known workers who provide this service in the Galway area? What sort of products should I use and lastly would it just be the wall dividing the apartment bedrooms or what else would need to be done?

Thanks in advance for any help anyone can provide

Interested in any responses to this as well.

From what i understand, plasterboard wall will have to be removed, insulation installed and new wall installed. Cost of around 1000 euro???
Any info appreciated as well.

Did some research on this before.

Google 'soundproofing room within a room'

Basically one leaves existing wall untouched and builds a new stud wall not connected (isolated) from the existing wall with the plasterboard on the new wall connected to the studs with 'resilient channel'. Some fit 2 layers of plasterboard to the resilient channel with 'Green Glue' between the two layers of plasterboard as well. Rock wool insulation between new and old wall. You'll lose a few inches of room area obviously and it's not a small job but tbh anything else is a waste of time effort and money.

The only thing that might get close to this and give you more value than just the soundproofing might be building floor to ceiling wardrobes along the full length of that wall. Fitting Rockwool to the existing wall and telling the carpenter to build the wardrobes in front of the Rockwool so to speak, not connected to the shared wall in any way with the back of the wardrobe being two layers of 20mm MDF as opposed to the thin and light backer board they'd usually use for the backs of fitted wardrobes. That way you'd be killing two birds with one stone. Soundproofing and more storage.

A window too close on adjoining perpendicular wall or general room shape/layout might put paid to that idea though obviously. Either way, one would also Seal/Caulk the ever loving bejaysus out of every tenny tiny gap every step of the way. All ones work can be undone by the tiniest gaps that let a surprising amount of sound through. Think about a car window. most of the sound enters the car after you open the first 3 or 4 millimetres.

Our Victorians party wall with the neighbours is 2 foot thick and yet I can hear the Italian student next door yapping away on the phone. I know they are loud feckers but jaysus. The sound vibrations are transferred through the solid wall because there is no isolation. no break. isolation by whatever method means the vibration has to transfer to the air across the gap and revibrate the new stud wall like a drum. The resilient channel and Rockwool and green glue prevents that by dampening the vibrations every step of the way.
