Soundproofing small home cinema room

[lnewey6]

hi everyone im hoping for a few pointers first off. i need to soundproof big time to stop the sound from my neighbours bass box.i can only use 2*2 studs i will use neostrips for the top , sides and bottom plates . is it worth using resilent channel. then i will use 1 layer of 12mm soundblock then sandwich the green stuff what they use for laminate in between then 1 layer of 15mm soundblock then seal or the edges . hope some one can help cheers

the bass will be coming through your floor too, so you wont get rid of that much by doing all that, though it will lesson some of it, why not go round and ask him to soundproof his side???

The effect of using the Resilient Channel is one that has sparked a lot of debate.



Using it does help further decouple your Soundbloc plasterboard from the original wall itself and it will provide a further 2-3dB of soundproofing if done correctly.



However the debate begins in that many people 'theorise' (I've never read of a single one of them actually proving it) that using the Resilient Channels will alter the low frequency in-room response of you kit, the idea being that decoupling the plasterboard from the studs will cause them to act as a huge diaphragm and 'suck out' the low frequencies from your system's sound.



I wouldn't use the floor insulating material as the filler between two sandwiched layers of Soundbloc, were I you. Infact I'd forget the resilient bars and attatch the first layer of soundblock straight to the studs, then line the soundbloc with two layers of acoustic insulating matts (available Here (http://www.customaudiodesigns.co.uk/soundproofing/barriermat.htm)), and then obviously another layer of soundbloc onto those.



It'll probably work out more expensive but it might be the solution you're after.



X3Els has some experience in soundproofing his HC room and I don't think he used anything other than rockwool and soundbloc plasterboard (no 'sound proofing matts' or anything), and his turned out to be very effective.

I would recomend the use of reislient channel or SoundBreaker Bars as otherwise known. The will create seperation in your wall structure which in turn will help to reduce the transmission of vibrational sound through the wall. People like Auralex is the US, a big respectable company, have been recommending it for studio build for years now.



They may lose the 'bass' within the room but will help to stop the transfer of bass out/in of the room.



Applying mass to the party wall area will help to reduce the directional noise in to your property but as Matt suggested the noise will also 'flank' (flanking sound) into your room through other areas, eg - under the floor, etc.



I would suggest to apply Dense Fibre Matting between the floor joists, and then a system to your wall, similar to what you where thinking. 2" x 2" stud, 50mm Dense Fibre Matting, SoundBreaker Bars and an acoustic board (http://www.noisestopsystems.co.uk/walls_sound_proofing.htm). I have seen this work a treat many times! You may need to place an isolation mat on the floor if youre serious about stopping the noise. Look here (http://www.noisestopsystems.co.uk/floors_sound_proofing.htm).



Whatever you do, do NOT use the rubbish they sell at B&Q !!!



Acoustic mats are good between plasterboard, also know as NoiseStop Barrier Shields.



Just remember...if its heavy, it should help....

Dennis Erskine has come across this effect so he doesn't recommend the use of resiliant channel due to the possible side effect you mention. IIRC, in one case a room had 5 sub-woofers but no bass, and resiliant channel was the cause. They had to remove the inner walls and strip out the RC and rebuild the walls. I can't remember the details of what else he did (if anything), but the room only needed one subwoofer to get good bass response after that.



I read the info over on avsforum so I'll try to find it if I can.



Here's some of Dennis's quotes:

Hi there, I was looking for something "easy" to put on my walls and I found some acoustic wallpaper, I haven't heard of it before but it probably could work, has any of you heard of this wallpaper?? is it any good?? http://www.mgcltd.co.uk/mgc048.html

Gerry

[mattrpg]

acoustic wallpaper, nice idea, probably wont absorb so much after a coat or 2 of paint though!

Is it me ? I know i would be pretty bothered if i was upsetting my niehbour with to much sound. Call it wrong if you will but i have two possible solutions.......



1. CHEAP, buy him some isolation spikes and offer to fit them and tell him all the benefits, that will isolate the sub from the floor and help somewhat.



2. EXPENSIVE, but cheaper than rebuilding, buy youself some bigger speakers, a set of monoblock amps, a decent av processor and some eardefenders from Arco ! and i guarantee, you wont hear his sub ANY MORE !



ahhhhhh, i remember a saying..... &quot;live by the sword.....Die by the sword&quot;





Seriously though, i would go for getting him some spikes, if you aint having problems with him im sure he would go for it, it does give much cleaner base with less boom. I would attempt soundproofing only if it where you causing the problem.



Or did i read the original post incorrectly ?

If you can just about hear the film i wouldnt worry too much, noise complaints only happen when excessive noise can be heard.



About the bass traps i dont know, i would post the question in the DIY forum here.



*edit* i see you have, you may want to change the thread title to be specific about the bass traps :thumbup:

I'd rather not go into it :D~:-D~:grin: Suffice to say that most everything that goes in normally comes back out again.



Still. Soundproofing eh? Discuss.



(there's some pretty clever people on here who know about trapping sound. I'm not one of them.)
