    Bass Trappn'

    It depends on the products you buy - some are made to absorb bass and high frequencies (and are still called bass traps) - while others might be 'bass only' traps. Best to check with whichever manufacturer what would be best for your space. Since you don't have much treatment in there to start...

    Setup with 3 Walls

    +1. If you have the open area to your left or right, your imaging will be asymmetric which will be very noticeable. Further the speakers on one side will have different boundary interactions than the other, which will skew the frequency response of the speakers on either side.

    Speaker Placement Question ?

    Wood is not absorptive, it is almost 100% reflective: as is glass, and almost every other rigid material. Putting laminate on top of a wooden shelf won't affect it at all.

    Am I wasting my time with a flat response?

    Part of the problem is that you're only inquiring about a very small part of the room's sound signature: the frequency response. A "flat" response might not be precisely what anyone is technically after. However, rooms have many other issues than just having a varying frequency response. In fact...

    Oddly shaped living room -- need suggestions

    Looks like you've got room for a television area, but not really for a "theater" as we know it! Have you been able to snap any other pics of the room?

    Sanus Speaker Stand Heights? How Tall Should They Be in My Weird Room?

    If you go with the 18" stand, you can always use some sort of supports to lift it up the additional 4" until you've got the couch in the room, no?

    Speaker placement/Acoustic panel setup help? (Awkard shaped room)

    Unfortunately with the brick you'll likely have a lot of low frequency problems that the foam can't address, but you should be able to get some overall reduction in the decay times for ~250 Hz and up. I would start with what's been outlined above for placements, and look to eventually get...

    Help with acoustic panel layout?

    You'll want diffusors in areas that send reflections back to you, but you also want them in areas that are distant from you to help control the overall ambiance. As for moving the desk, yes, that would be best. Really the point of doing so is to center the speakers in between the two walls.

    Help with acoustic panel layout?

    Hi there, Being a much smaller space in volume, and having likely much more 'wall' closer to the speakers, the sound will be dramatically different as you've experienced. Acoustic panels absorb sound, and so they're usually used to treat close boundaries so that really intense reflections are...

    Dedicated HT Room advice

    Insulating around the ducting will reduce those vibrations you hear. Otherwise, treatment is usually looked at for a lot of the front wall in a home theater, as well as the first reflection points on the sidewalls and ceilings. Bass traps are usually used in the corners and on the rear wall to...

    Suggestions for acoustic dampening

    Panels behind the speakers would help with SBIR. I would definitely suggest panels on the back wall, especially if you can't get any in on the side. Foam could help on the side of the couch, but I'm still not too sure if it's the cause of the phenomenon you're encountering. You could try a...

    Suggestions for acoustic dampening

    Ah that makes much more sense now. Yes, the reflections in that small area could create a seemingly second source, but leather would only be reflective of high frequencies. Most lows would just pass through. You could absorb on the side of the couch, but IMO a better solution would be to simply...

    Suggestions for acoustic dampening

    Sorry could you elaborate a bit more? What exactly about the end of the couch is causing issues? And what type of issues would it be causing? Packing foam is useful for packing/shipping. Packing foam is also typically not fire treated and typically lights ablaze instantly. I wouldn't recommend...

    Noise Isolation for 3rd Floor Theater Room

    It can get much more expensive than building another room within your room. Thats actually one of the cheaper ways you can go considering the room is already built. I would recommend getting a book or two on the subject if you don't plan on hiring a professional and reading for a bit. I...

    Suggestions for acoustic dampening

    Is there any specific reason you are situated as such? I would recommend putting your speakers against the 13' wall, with your seating position symmetric left to right in the room. But to answer your exact question, yes. Panels at first reflection points on sidewalls and the ceiling will be...

    Help with acoustic panels

    It depends on the problems you're having. If high frequency flutter echo is a problem, then foam would help. If you're having problems in the bass regions, foam would likely not do too much to help. You do have wall/ceiling corners you can mount panels onto - there are 12 corners in a room, not...

    Help with acoustic panels

    Sitting right next to a wall can give you some notches in the frequency spectrum. The reflections off the rear wall will arrive at your ear right after the direct sound, and will phase certain frequencies very easily. Panels behind your head will, as you suspected, absorb these reflections. So...

    <Request> Suggestion on Placement of the front left and right speakers of 5.1 ch HT

    Though the speaker would likely determine some of the answer to your question (as the polar response of the speakers would be important to know for a question), a bigger factor would be the acoustics of your room. DRC is certainly helpful, but won't solve problems in the time domain (which...
