I suspect that the sound level in the SimRoom will be quite high while racing (both from the sounds in the simulator and potentially a motion frame) - I am thinking about ways to reduce the amount of sounds coming OUT of the room (e.g, someone might be watching TV downstairs and don't quite find the loud engines as amusing as I will).
There are plenty of ways to reduce sounds but I won't go overboard here and sound insulate the walls with a layer of concrete, another layer of plaster board, yet another layer of 5" insulation and so forth. The room is quite small (3.7 x 2.2 meters) and it currently has wooden floor and normal wallpapered walls. I'll cover the floor with a new thick (as thick as I can find) carpet (my British wife will be happy about this :) to dampen any sound but also to protect the floor from any motion simulator movements. I suspect I will regret this later when dust settles in the carpet, but never mind, I can rip it out if it gets on my nerves!
For the walls and door, I am looking for some type of absorbing wall paper and paint. I found "Acousti-Coat". The manufacturer claims that mid range sounds can be reduced about 30%, so and how much of a bluff that is I don't know, but I am quite sure it won't crease the sound emitted from the room so it's worth a try.
There is a good article about sound isolation and noise reduction that explains how sound travels and how it's effectively reduced. It is more aimed at the home cinema / recording studio audience, but I'll be digging for useful tips and tricks in there. Only two things stops travelling sound and that is mass and space.
If you have any ideas or experience in how to effectively reduce sound being emitted from a room I'd be happy to see it in the comments =)

I think it will be much cheaper if you buy some earplugs for your wife...
Mate i think you are on the right track with that you suggested. You might wanna check what musicians use to dampen the sounds in rooms. They might got materials aswell.
Haha, what a great suggestion - I can't argue that it would be cheaper and probably very effective!
I ordered 5-gallons of the Acousti-coat paint 2 years ago.
Either the batch I got was not good or this is not a practical product. I thoroughly mixed the paint and applied it to a primed wall and ceiling. It is a very messy product, it does not go on smoothly or easily. It clumps and drips like crazy, as well as clogs the paint roller and brush. It has a chalky, soft texture that does not stick as well as paint. The beads want to clump together no matter how much you mix them up and they create a very blotchy texture. Once I began I realized that I would either have to begrudgingly finish the job or go through the pain of removing what I had put on already. Neither option was appealing, but I continued to paint. Its a horrible product to work with and I would not recommend it to anyone and any sound reduction was not noticeable.
