Author Topic: Point me to the right dealers Steve Kraus Film God Posts: 4094 From: Chicago, IL, USA Registered: May 2000 posted 11-07-2003 03:50 PM                    First of all I need a couple of 4' pieces of lighted step treads. I wish to reduce the noise level within the booth so I want to cover the hard wall surfaces with sound absorbing materials. I don't want something that gathers a lot of dust. At the post house I used to work at our screening room(s) interiors had wall coverings made of compressed fiberglass with a cloth cover. I dont recall the name. Is something like that available in smaller tiles rather than large panels? I was also thinking of removing the existing drop ceiling tiles (2' x 2') which are supposedly acoustical and replacing them with tiles that are more absorbant. In both cases they must be fire retardant of course. So...looking for sources for these various items.  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 11-07-2003 03:59 PM                        Links: http://www.thelightingcenter.com/products/8/ http://www.sonicequipment.com/tivoli.htm http://www.enterpriselighting.com/linecard2.html http://wulfinstallations.com/products.html Try Tivoli, Tempo, Tokistar, LED, Celestial, as brand names that make aisle lighting for theatres.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 11-08-2003 10:58 AM                     A lot of booths up here have a accoustic tile made by Armstrong on the walls (it is very similar to fissured ceiling tiles but 1x1)  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 11-08-2003 09:53 PM                     Steve, Get some 2X4 sheets of duct liner and cover them with something that approaches acoustical transparency and which has been flame retardent treated. Also get a fire rating certificate with the cloth when you purchase it....thats normally free. The ductliner comes in a variety of thicknesses and should meet Chicago Fire codes. 2" thickness should be adquate. Also, take a good look at your floor there. I seem to remember it was just a plywood with carpet over it. What works good there is to sandwich plywood / 5/8" drywall / plywood. The top floor surface should not touch any of the walls. The drywall and decoupled plywood will stop alot of the sound thats comming down through the base. Also consider building acoustical hoods so you can throw away the port glass...another point of sound transmission. A decent acoustical hood that butts up to the lenses and the projector end and flares out to port size will actually drop sound level going through the port by about 30 db more than the glass will. You also get rid of the piece of glass thats in front of your multi thousand dollar lenses. Interestingly, the original Sycamore Theatre had 4 acoustical hoods!! Two for flat and two for scope. Sounds like some samples of aisle lighting is just what you need. Just call any of the aisle lighting manufacturers and tell them you're Roger Eberts personal Projectionist. Bet they'd be glad to send you some decent samples at N/C. If they won't just let me know. Samples are never a problem.

I'm trying to quieten the booth, not the screening room. Just tired of the noise. Booth floor is concrete with tile.  |  IP: Logged
