Sound isolation is important to me, took a gamble on my flat, thought because it was purpose built the soundproofing would be adequate, it is not so I need to fix it as it feels like im living in someone else’s house.
Unsurprisingly it is really expensive. Got a quote for materials of £1400 and assume £500 for labour. Got a quote from a company that provides the materials and installation for £3500!
I am wondering if I can do it myself on the cheap.
The recommended approach is stuff the floors with acoustic mineral wool, and then use soundproof mats over the top. The mineral wool, while being pretty cheap, would be the difficult bit as involves ripping up the floor. On its own it only provides a 2db reduction, but apparently when used as part of a bigger solution it has a greater affect.
When used with these mats its a 54db rather than 43db difference
|dB||Actual SPL reduction||Perceived Volume reduction|
As it seems to be a 94.6% reduction without the wool and 97.6% with it, I’m inclined not to bother with the mineral wool as I wouldn’t have to pay someone to lift the floorboards, wouldn’t have to worry about the electrics and pipes that might be under there. I think I can do the soundmats myself so would only cost £1000 for the materials. But having said that why would anyone bother with the wool if the perceived difference is so small?
Finally I have found a cheap alternative. This stuff
I could do two layers for about £520 which would give a 29db reduction so about an 87% perceived reduction.
A big consideration is the disruption, it will be a pretty big effort to clear my living room out so I kind of want to get it fixed once and for all, but I obviously don’t want to pay huge amounts
what does the hive mind think is the best way to go?
- Pay £3500 to get it done professionally
- Pay £2000 to get it done semi-professionally
- Pay £1000 and do it yourself with the sound mats
- Pay £520 and give the cheap option the shot
- No-one is going to read a post this long
So yeah, what is the point in mineral wool, anyone had good bad experience with sound proofing? Also how to the physics work, seen a lot of things that say sound flows like water so that if there are any gaps it will find a way. Initially I was skeptical of that, surely a lot of it must be absorbed and only some leaks through, or is it a case that sound only gets blocked/absorbed if there is nowhere else for it to go, and it takes the path of least resistance?
Also seen pictures of things that soundproof the insides of plug sockets, surely that is overkill isn’t it?
