Home theatre in-wall acoustic design?
Page 1 of 1
Building a house with a home theatre. About 16m2 in size. Just wondering what are the common and reasonable things people do to improve acoustic in the their theatre. For starter, my builder don't have extra thick wall built around the theatre. So what can do I do to improve the acoustic? Read somewhere before people put some acoustic panel inside their wall? Seen those external panels, but I personally would prefer internal foam. What is it called anyway? And how would you coordinate with builder to put them in before they plaster up the wall? Is it worth doing it? Cheers
I think look at avsforum build threads for a similar sized theatre and see what they did and how the approach was taken. This will allow an overall plan of attack. Regarding the walls you could use rockwool or something like acoustic batts but not sure what the goal is whether it is to stop sound bleed out of the room or to improve the internal sound.
More info pls....
Soundcheck plasterboard and soundscreen batts.
Good suggestion, sound like just the stuff I need. Shame they don't have distributor in WA? Have a feeling it might cost me fortune to get them shipped here
Well the room dimensions itsself are important. Use an online calculator to see whether your room dimensions are ok... well worth checking because if you have standing waves it will cost more to treat the room. As brettbert says, soundcheck is a good start but you need to decide how far you take it. you can double skin the walls and have the second skin isolated using green glue etc but this start to become expensive.

I think this is the basic one. You will need excel. You can also search for carlton-bale room calculator http://carltonbale.com/home-theater/hom ... alculator/

Have a read of this and the Next & Next+1 pages. Note that ratios also depend on the total room volume.

In the end, the Acoustics of the room is what really matters, so consider your needs for budget in case you overspend on isolation.
For isolation between rooms, a different subject altogether, using thick or double sheets of Fire Rated Plasterboard and low-density insulation, eg Earthwool 10 kg/m3 is very commonly used in Studios.
I have not known an Acoustic Architect who has specified Soundcheck or batts. If you really need isolation use 2x13mm FR Plasterboard, maybe Resilient Clips and 16mm Furring Channel on the inside walls, and use the money you save on Green Glue between sheets.
There are Home Theatre Forums with more details, but you can also check Recording Forums, like Gearslu-tz (remove that hyphen) and John L Sayers recording forum. Both have threads with heaps of detail.

The answer to these is different.
Preventing the leakage of sound to other parts of your house can be done with how you line the walls and ceiling, such as soundcheck or similar, multiple layers of it with green glue between the sheets.
The other is producing the best sound in the room, which means the size and shape of your room, which you can work out from the calculators that TezzaB and AussieMark have posted earlier on.
The main question is what do you mean by accoustics? Are you trying to prevent leakage of sound to other parts of the home, or are you looking to treat the rooms accoustics to ensure your nice audio gears sound is not being coloured by standing waves and reflections?
The answer to these is different.

Yes, you're right. The more I read about acoustic is home theatre, the more lost I am lol
Actually I think I just want to keep the sound, and not have too much sound "bouncing" in the room like my precious uni small room. Not sure what I need, but I'll just work on thick curtains and some acoustic panels on ceiling & batts in wall. Gonna be too much to ask to get my builder to use a different plasterboard I thnk.
The heavy curtains should be wavy, the theory being that the curves will deflect sound that is not absorbed at different angles. Why put acoustic panels on the ceiling, are your speakers pointing to the ceiling. One way is to have someone with a mirror move along the walls and you move from seat to seat and mark a chalk x when you can see the speakers in the mirror. That is where you can put some of your acoustic panels.
I mate of mine that is right into hifi had to work with a bedroom as his music room and over time he tuned the room in to what it is now and it sounds amazing. Just take it slow and try some things out.....
However I get the impression that you will be will be using a standard $2k audio set up from a retailer for your HT. If so, I wouldn't bother too much about all the various technicalities of treating the acoustics of a room and just make it nice and comfortable. The likelihood you will notice any major sound/reflection issues is probably zilch if you're the type of person who cant tell the difference between an MP3 and a 24bit 96khz recording. Not a bad thing, just highlighting that you might benefit more from saving your coin for more desirable things in your home than treating a room for an issue you will likely never perceive.
/cue audiophiles who disagree (but before you do, as a fellow audiophile, how many times have you seen DJs mixing 128 bit MP3s through sound systems that cost in excess of 100k and not even realise themselves that it sounds like poo?)
