    Don't forget the portable decay reactor... j/k

    I did this to a wall shared between the living room and a bedroom resulting it a much quieter bedroom. If the wall you are working on is not insulated, be sure to do that as well.

    Two outside walls, one screen wall slightly offset from an outside wall with a bay window and one shared wall that is half foundation and half framed. The ceiling will also be done as there is a bedroom above.

    Shared wall will get the double 5/8 drywall with the green glue on the clips. The framed portion of this wall will also get roxul rockboard insulation followed by 4-6 layers of drywall polyurathane glued into the cavity. Ceiling will be the double drywall and green glue clips followed by insulation followed by 4-6 layers of drywall glued again. Subfloor of the room above will also have the joist tape under the 3/4" osb.

    Also plan to do mufflers on the havc vents and cold air return into the theater. The hope is I'll be able to watch a movie at a reasonable level with everyone else sleeping.

    Mufflers on the HVAC. Do you have a resource for these?

    Ambitious. You seem to have done your homework.

    Ah, yes I am familiar with Dr. Geddes approach and I do have this essential text. I thought you meant you had found a product you could purchase off the shelf and just install rather than build it. :)

    I've got 7 DIY Soundgroup kits to build, 2 18" and 3 12" drivers to build into new sub boxes, a screen and 4 way masking system to design and build, the mufflers and the whole room to build. Electronics and chairs will be about the only things I don't build for this room.

    Although if there was a ready made effective HVAC muffler I would likely buy it.

    Duct silencers exist, although I have not used them I've been tempted to give them a try

    Those look interesting, although it appears they are targeted more at commercial use than home use.

    Bin was delivered on Thursday. Managed more or less to completely demo the existing master suite yesterday. Onto the existing theater today. 7842ac4757b29341f8747b02db83f535.jpg 71d7311c646f36af0d9c377e2ad156de.jpg 968ba791e4783abb64f8cf25364febb2.jpg

    Likely won't have the bed back in the room until September or October and the bathroom will be longer than that. Might get it done faster. Will depend on how much time I take off work.

    She wants the end result so she's on board with the process.

    Ramp constructed and moving onto drywall removal in the theater room after the riser is all the way out. Not looking forward to removing all the insulation from this room, especially the ceiling. 224225a9554937181fc3dd9f76fa1ba6.jpg 347cdbf90107bf204f2378f33e58b37b.jpg db95f34b5d5e21aa7b8b1a15e7886272.jpg

    thermaflex MKE is the commercial version of the muffler. I use this on every lead when I do a house (rarely). 2 or 3 feet is enough. It is about 10 times as restrictive (air flow) as metal duct.

    Silencers are a thing. For a short time I was actually making them for the largest supplier in North America. They are expensive to ship, so they try and get local companies to make them and ship them to the local market from those companies. It was not profitable, a bit of a pain and I stopped it after about 6 months. There is a lot of engineering there, they are also very restrictive and different materials are used for different applications, and done properly they are very heavy. Not something I would ever put in a house, or on a system probably smaller then a 10 ton unit. Most houses use a 5 ton or less, or multiple 5 ton or less units. A modern house is built using say 750 square feet per ton on main floors and 1500 square feet per ton in the basement. So true silencers are just pain overkill and probably more hassle than they are worth.

    There is also interior acoustic lining for duct, this is cheap effective and makes a huge difference. Comes in a roll and is applied to square duct with weld pins and adhesive. Comes in a different roll for friction fitting to the interior of round ducts. We do this all of the time, every single day.

    Didn't get quite as far as I wanted today. Went back at it after supper to finish removing the drywall from the last wall.

    Don't think the bin will fit all the insulation, the ceiling drywall and the subfloor. Looks like I'll be making a couple dump runs myself. 0b17b4057bfbdbf17c029829218b7166.jpg d5676ed2888430d6a985c70a3dd10241.jpg d7456fa46f5329c4c6e81dfbb5c53069.jpg
