I will keep these suggestions in mind. I really like the 3/4" MDF idea because that would be very cost effective for out needs. As we are a campus organization we do not have a huge cash flow and MDF or ply is easy to get. I think one of the people was going to do the Auralex room eval sheet to see what they say but never got around to it. The RPG website has some good articles I just started poking through. Now heres a question, we have a wall made or 2x4 and cheep dry wall separating control room and "live" room. Any ideas on a cost effective building method/materials for building an acoustically insulated wall that could be outfitted near how the cement walls are?
Interesting to see a fellow ham that is knowledgeable about acoustics and is a robot guy on here.
