Impact noise from neighbours

i think this is the problem. There’s lots to consider.
Our gate is attached to the side of the same wall. This can be felt too if it shuts or is windy, so did think decoupling this from the wall may help a little.

We have been quoted for the ceiling and the 2 direct walls with window area. Comes out at around £7k. This is with iKoustic products and installation from professionals (Don’t trust ourselves to do it haha)

It’s expensive, but then I have to weigh up the cost of moving to another detached house is probably 100k more in our area.

Our biggest fear is we pay this much money and then it hasn’t helped at all. Guess it’s hard to imagine it…

Sound apparently travels like water (finds the nearest gap), so what about the floor? Or the side walls?

Well one of the walls treated would be the side wall. The other wall is not an issue according to the soundproofing consultant.

He did mention that we could always do acoustic underlay after rather than spending loads in one go. Think it would be better to do it in stages like that.

As I said, outside the noise is what you expect. Can just hear it. It seems like our hollow walls with the dot and dab and the hollow ceiling are the main culprits. They amplify it a bit like a drum.

Fingers crossed for you. I'm at the debating stage also, unfortunately the sound comes from all over so I'll have to do all walls, floor and ceiling, as I think if you're doing it then might as well go all in.

I hope you manage to get it sorted :)

We originally thought to just do the 2 main direct noise path walls, however we don’t want to have twice the inconvenience of having the room ripped apart again for the ceiling later.

What doesn’t help in our case is that the windows themselves are also awful. We can hear word for word conversations outside even with them closed.

Yeah, same here regarding windows, although I can deal with the external sounds relatively well.
 
I think this is why I’m trying to rationally think about the whole thing.

A bit disappointed that we bought detached yet still hear quite a lot of noise. Didn’t expect silence, however this is way above what I was expecting.

We have seen people block their trickle vents and say it helps a lot. Bit reluctant to do that because of moisture issues.
 
If you were to drill 10mm holes into the plasterboard you could easily fill the voids with expanding foam. A bit unorthodox but it would work in theory. It wouldn't be difficult to filler over either as it adheres well to foam.
 
If the source is vibration/impact sound then won't this make it worse?
My thoughts exactly.
Just been down the side of the house to make sure I’m not going crazy. So can 100% confirm that me stamping my feet sounds way worse in the house than it does outside. Strongly suggests that the house material is amplifying the noise.

Is it impact noise or airborne as they both have different soundproofing requirements?

Impact noise usually requires soundproofing decoupling to break the bridge of the noise/vibrations through the walls where as airborne can be just soundproofing attatched to the walls. Did the soundproof company mention any of that?

Yes they did. To be fair they have been extremely helpful. Their system is basically going to be furring channels with mute clips that decouple the structure. Then acoustic plasterboard with MLV and more dense material. The ceiling will be similar but with the joist filled with Rockwool as well.
 
Just be mindful when a company puts acoustic or soundproofing in front of their product/service you're going to pay a premium for buzzwords.

Skimmed the thread but if you're feeling kids running then the best option is physical decoupling...perhaps there's something you can do along your fence like dig it out and replace it different material that won't transfer the impact noise.

Airborne noise is treated in other ways and will always find it's way through the weakest point (like trickle vents). To treat airborne you need airtightness and mass. The room is only as soundproof as the weakest link so no point spending money on sound proofing a floor if the windows have a low STC value.

Thanks Joe :)

Don’t get me wrong, we are definitely going into this cautiously.

The side of the house is an interesting one. As wouldn’t we have to dig essentially a really deep trench for it to be effective?

We do keep thinking could we do the soundproofing installation ourselves. However, I’d be too worried about installing it incorrectly.

Our windows are definitely an issue too, but less concerned about that as it’s nothing secondary glazing can’t fix.

It's a tricky one but if you're feeling the sound of kids running then it must be travelling through the ground. It could be something you can't change like concrete foundations joining the properties (why I wouldn't know). Or maybe it's because the paths running down the side of the fence are physically coupled by the fence posts and the foundation. Separating these will reduce the physical transmission....certainly needs more thought into the correct solution but that's the likely culprit for what you've described.


Soundproofing sounds difficult and this is what the 'specialist' companies want to sell their services on but a lot of it is just common sense when you think about how sound travels. Soundproofing is just looking for weaknesses and addressing those. Some of it is easier to DIY than others. Like in an old house make sure every gap is filled with caulk, or thicken up the walls by using two layers of plasterboard (stuck together with carpet adhesive) which adds mass and vibrational dampening.
