Machine space considerations All wiring (including analog phone line) to machinery space supplied by owner. Local codes may vary. Consult with your architect/ engineer and local Schindler representative. Sound suppression The following guidelines are to be followed to reduce noise to acceptable levels: 1. The surrounding walls, floor, and ceiling assembly should have a substantial STC (Sound Transmission Class) rating. The higher the STC rating, the better. If noise-sensitive areas are nearby, STC 50 or 55 should be used as the design criteria for the surrounding structure. Concrete block walls will provide STC 42. Two layers of gypsum board on each side of 3 5/8” steel studs at standard spacing (total of four layers, two on each side) with fiberglass batt in the cavity will provide STC 56. All cracks and gaps around the perimeter must be copiously filled with the appropriate acoustical caulking. Wood studs should be avoided, but if they are used, attach drywall with resilient channel or use a staggered stud arrangement. 2. In situations where noise-sensitive areas are not an issue, two layers of drywall (four total) are still recommended and sufficient caulk around the perimeter. Double-layer drywall with staggered seams works best. 3. Penetrations into the hoistway must be kept to a minimum. When conduits pass through the walls, they must be sealed with mortar or the appropriate acoustical sealant to prevent noise leaks. A heavy, solid material must be used. Do not use fiberglass. 4. If the walls are concrete block, do not paint them. Unpainted block has about 33% absorption, which is lost with a coat of paint.
