How to Build a Media Room
Posted 06/12/07 at 02:48:20 PM | by Michael Brown
Given the fact that I’m building a new home from scratch, I’d be crazy not to take the opportunity to include a kick-ass media room. Budget constraints prevent me from going completely over the top—there won’t be stadium-style seating, for instance—but I do want to render the room as acoustically neutral as possible.
I’m doing this for both selfish and professional reasons: I’ve always dreamt of having a great media room, and this is the perfect opportunity to create an excellent environment for real-world testing of many of the products that I cover here at Maximum PC—especially speakers, video projectors, A/V streaming gear, and wireless network products. I also want to prevent sound from leaking out of the room into other parts of the house—especially since my master bedroom is on the other side of the wall. What I’m doing is made much easier by the fact that I’m dealing with new construction, but it’s not something that would be impossible as part of a remodel.
A good media room should be rectangular, not square, with a uniform ceiling (cathedral ceilings look impressive, but they're acoustically terrible).
The room in which you listen to music, watch movies, or play games can have as much of an impact on your sonic experience as the speakers and amplifier you deploy in it. The room’s walls, floor, and ceiling reflect sound so that you hear it emanating not only from your speakers, but also from other parts of the room. These reflections can enrich the sound and make it fuller and more natural, but they can also distort sound by amplifying some frequencies while canceling others out altogether. This can lead to boomy-sounding bass and harsh mid-range and high frequencies.
Dead air is effective sound proofing, but fiberglass insulation is even better. This room consists of a 2x4 frame within a 2x6 frame stuffed with two layers of R19 insulation.

And I thought you guys were just computer geeks...this is a welcome change of topic. Will the full write-up be in the mag? This is good stuff...I'm buying a house right now and this gives me a new idea.
Double walls are good. But

Double walls are good. But another option is to use 2x6 plates and stagger the 2x4 studs to the adjoining rooms. This provides a break in the sound transmission (except for the top and bottom plates). By staggering the studs, you break up the possible transmission through the sheetrock some more.
Use the sound damping sealant/adheseive on each stud before hanging the sheet rock.
Saves some money on materials and uses less space.
I think this will still be a fairly lively room. Not dead by a long shot. There will still be a lot of ambient reflections from the sidewalls, floors and ceilings as well as from objects in the room. The room dimensions yield a good ratio for combating negative sound characteristics but still offer positive reinforcement for the listener.
AWESOME!!! I'd love to be

AWESOME!!!
I'd love to be able to (afford to) build such a room for practicing/recording with my band out in our shop...
I'm in planning stages, but will probably be a couple years before I can afford all the materials needed :( The good thing is I can do all the labor. I have plenty of carpentry experience, & most of the necessary tools to get the job done quickly & easily, just don't have the income at present to build in a timely manner
If I ever get the chance to have a home built for me, it will definitely have a home theater/media room built into it :)
I hope to hear more after your house is finished & the room is in full use!!!
Good and not that great. You

Good and not that great. You are taking the myths of audio to heart. You see, one doesn't want a "dead" room because the room is the x factor when it comes to the ultimate sound quality. I have been touting that there should be some liveliness to rooms where speakers are listened to. I can't pinpoint or calculate the effect, but I can say for certain that a 'live' room can do more good than harm.
Another thing, your definition of standing waves just wouldn't work. Energy is lost from reflection and a domino effect of phase/harmonics are set off when a sound wave encounters a wall. Anyhow, the definition as it 'stands', is that standing waves exist along the dimensions of the room and for wavelengths longer or equal to those dimensions. But, don't get all twisted up about standing waves and the like, it is the x factor remember?
Also, if you don't agree, check out www.linkwitzlab.com and more specifically the ORION++/ORION+. Maybe MaximumPC can review a REAL set of speakers where they don't try to "educate" readers on what is "best" and instead focus on the sound quality-like they use to.
