From: "Jim Saenger" <chamade@Early.COM> Date: Sat, 16 Aug 97 09:53:46 PDT   The best lining for pipe chambers is a matter to be decided, one chamber at a time! In so many cases with typical 20th century chambers, drywall/sheetrock/regips is the surface treatment of choice. With brick, concrete and masonry working with adequate thermal insulation, excellent results can be had without much of a surface treatment. Again, the chamber itself and the musical requirements best determine the approach.   Very often, especially in smaller chambers -for whatever application- the geometry of the room may be more influential than the chamber lining. The strength, weight and rigidity of chamber surfaces can also be as important as the surface treatment. Multiple layers of sheetrock, ideally of different thickness, with irregular studs and cross braces is a popular and thorough treatment in many cases.   An interesting study was done when the Limburg, Germany cathedral organ was built: This organ is in casework, with a swell division enclosed in C and C# sides. One side of the swellbox was built with multiple laminations of the same thickness of wood. The other side was built with layers of different weights, to the same finished thickness. The frequency response was somewhat different between the two sides.   Jim Saenger         ---------- > I'm wondering what would be the best material to use to line the walls of a > pipe chamber in order that it be as "reflective" as possible. > > Normal building material like drywall sheetrock seems to me to be mighty > porous and thus inappropriate.

And all of that is equally as important as the room's reflectivity   Good luck! Paul Stapel

That oughta do the trick.   More seriously, I don't think you could go far wrong with gypsym wallboard--though furnature grade birch plywood might give you a bit more organic sound     Charles. > Asbestos is natural > Benzene is organic > Try our new asbestos chips w/ benzene sauce! > Their natural and organic!
