Neighbours loud sex/soundproofing a shared wall

[TwinMummy30]

Anyone has ever soundproofed their wall to cancel their neighbours noise coming through? Did it make any difference? Which product can you recommend? Any advice would be great.
They have loud sex nearly every night, lasting 1-2 hours where she screams all this time. It stops us from sleeping and we’ve started having anxiety issues. Talking to them is not the case as it would only make matters worse.

Go and ring or knock on their door, keep knocking then IF they answer ask if everything is OK as your children said they could hear a woman screaming next door ! X

We sound proofed all the adjoining walls in our house when we moved in as the walls were paper thin. We were doing it as part of wider renovations to our property as beware it is expensive and messy and you will slightly reduce the size of your room.

We researched online and bought a sealant called Green Glue which is a bit like decorators caulk or the sealant you put round the bath and is supposed to have sound proofing qualities. You seal your floorboards and fill in the gap where the skirting board is and any gap between walls and ceiling.

Then our plasterer built a new stud wall along the adjoining wall about 7cm into our rooms and stuffed rock wool (the stuff you insulate your loft with),then covered it with acoustic plaster board, plastered over the top and then we sealed in the cracks etc again with the green glue.

You then stuff more rock wool up against the adjoining wall in the loft.

Like I said we were modernising our property so we also had each room completely skimmed by the same plasterer so hard to say what it cost just for the soundproofing, we paid £1000 per room for Labour and materials including all the plastering.

It reduced the sounds about 30% I would say, so not amazing, but just took the edge off, and gives us more privacy too. Can still hear them walking and banging around, dogs toe nails scratching the floor and windows, whistling or singing, and hear the sound of conversations and some words, but can only really discern the exact words when they're shouting. We can hear their tv and feel the vibrations still as it's attached to their wall, but it's quieter. So a bit like hearing them underwater, only bit louder.

The other downside is that we can't ever drill anything into the plaster boarded wall as if you pierce the board it obviously means the sound can get through as will break the seal. So no picture hooks, shelves or securing furniture to the walls, which is a bit restrictive.

I still think it's worth it, but there is no miracle cure. We did upstairs and downstairs and it got progressively better as each room was added on, the first room on its own wasn't as effective.

Sorry for the long post, I hope you find a solution that works.

@TwinMummy30 Sorry already suggested but these are FAB and I can vouch for them (I got them from a different seller but the actual product I can vouch for - they even work for fairly loud musicians who live in adjoining flats and share a wall -** might be worth a go even if a short term solution :)

sorry if already* suggested

Thank you so much! Will have a look

@VickyMcCluresAccentThough did you use to block the noise coming out or in?

@TwinMummy30 to stop it getting out of a music studio room to make sure we didn't annoy the neighbours whose bedroom was on the other side. Worked a treat!

I’m going to embark on a party wall sound proofing journey soon.

I’ve done some prep work so far...

Whilst I had all my floorboards up, before sanding I stuffed all my floor voids upstairs with rwa45 rockwool. This stops all sounds below 55 decibels coming up from downstairs in my house and reduces some of what I assume was flanking noise from neighbours upstairs.

Just a weak point I had to tackle with the bonus that I can no longer hear the downstairs tv if played at a regular volume!

My party wall is 13 inch thick solid brick but as it’s solid and no cavity it doesn’t perform great :(
I’m estimating I hear any sound over 40db. I get to this conclusion as I can hear general conversation with some clear words and tv etc. The main reason I say 40db is I hear their hoover at 40db and most hoovers are 80db.

They’re not loud people and keep the same hours as me. They can’t help their general day to day noise so I have no reason to complain at the fact they watch eastenders at 80db whilst i would do at 55db. Basically it’s mine and houses problem. Not theirs.

But if I can up sound reduction by 20db it would mean I would have to strain to hear what I hear now and would no longer be intrusive. It would be like what I’m used to in the past, just hearing loud noises, Hoover, shouting, parties, occasional movie night... this would be bliss.

Plan is to do work in the worst room but also the room with 2 bookcases so I don’t have reinstate skirting,coving,picture rails etc. Because there is a chance it just won’t work and it will all be wasted this way atleast it’s behind the bookcases!

The plan is

. Unscrew bookcases
. Take off skirtings and coving behind (if any)
. Sound board any exposed bits of ceiling/skirting
. Green glue perimeter and any gaps

. Rubber matt wall
. Batten up to 50mm
. Fill with rw5 acoustic wool
. Resilient channel
. 2 Layers of sound board with staggered joints with 5mm perimeter gap
. Green glue gap
. Plaster
. Cut down book cases
. Reattach into sides of walls
. Hope for 20db results!

May change his configuration slightly but only have 120mm to play with whilst still allowing the book case to be deep enough to be functional.

I will start a thread with results if it works and then do the rest of the house. Matching all the wood work and coving is going to be crazy expensive... but worth it if it works.

If you can’t beat them join them?
Not literally but maybe start a party of your own.

Have you banged on the wall really loudly while they are 'enjoying' each other. Maybe they don't realize and you can shame them into quieting down?

I'd call the police and say you can hear the woman next door screaming WHAT

Any way you could poison them? It would be kinder to put them out of their misery.

I have just put up a soundproof wall as detailed above, filled with rock wool.

It has worked really well in terms of tv sound- you now can't hear it at all, previously it was clear as day! It cost £1400 for steel framed false wall, rock wool and soundproof plaster board and labour. We lost about 4 inches of the room as well.

Who on earth has sex that long and often!? Hope you find something that ends your misery OP.

Thank you everyone! I’m off to Wickes tomorrow and praying it’ll work.

@CookPassBabtridge and they are in their mid 40s 🤔

I wish I still had the energy for two hours every single night lol.

Anyway, I know you seem to be avoiding confrontation here but I would honestly knock on their door and ask them to keep the noise down. They are the ones being rude and intrusive, not you. They should be embarrassed and apologetic at even putting you in a position where you need to come over and speak to them about this. You might find that they have no idea you can hear them and stop it.

If things don't improve after your talk then just contact the police/council. if it's loud enough and late enough they will be forced to be quieter or get fined.
