(back) Subject: The Organ Room... From: "John Haskey" <johnh@powerinter.net> Date: Mon, 13 Nov 2000 10:18:18 -0800     Some time ago I asked the list for advice regarding the new Organ Room to be added to my house. I collected all the responses (thanks very much, by the way) and had them on hand while discussing things with the architect. It looks like the outside dimensions of the space will be about 18' x 36'. The architect has asked if it would be o.k. to have two trusses (dividing the ceiling space into 12' segments) to eliminate the need for a long expensive ridge beam. Anyone think this would be a problem acoustically? I think it might add to the appearance of the room somewhat...   ---john.

Trusses, exposed and made a "feature", can look quite nice. I've seen several buildings recently in which normal trusses, made of 2-by lumber, were stacked in groups of 3 or 4 to simulate a heavy-timber frame. When painted, and fitted with "covers" for the metal connectors, they can look quite nice. One set was on the Shanklin Conference Center in Groton, MA, in a 300-seat auditorium that is home to a wonderful 4/34 Wurlitzer. The trusses there span 46 feet and add 12' to the 24' sidewall height; the room is about 96 feet long, with a balcony area at the back and a rear = wall that is somewhat curved (convex into the room) to help avoid standing waves. (The September/October issue of "Theatre Organ" has a nice article on this room and instrument.)   That, in fact, is the other thing about John's room dimensions. If two of them are 18' and 36', then both dimensions would tend to have similar resonant frequencies (for standing waves). Adjusting them a bit might help, as would providing additional surfaces to break up the standing = waves.   Hard surfaces, rigidly supported, will also be good; you can always apply rugs or wall hangings later if there is too much resonance!   John, best wishes for your project! What sort of instrument do you plan = to have? (Perhaps you've told us and I've forgotten...)   Larry Chace
