It is well documented that acoustical insulation can dramatically improve the Sound Transmission Class (STC) rating of partitions. Masonry STC-60 construction is effective for isolating music, but one needs to be careful with gypsum board construction because it typically provides poor performance at frequencies below the 125 Hz lower limit of the STC testing range. Double-wall construction provides total acoustical separation of the two walls with an air space which is typically filled with sound-absorbing insulation. 1. Tests have proven that the construction employed has integral high resistance to impact damage, low thermal conductivity and high STC ratings. with 1” Type S drywall screws 12” o.

Handbook 119, July, 1976: Quieting: A Practical Guide to Noise Control; Page 61. Concrete masonry walls are often used for their ability to isolate and dissipate noise. lize gypsum products to provide fire resistance to walls, partitions, floor-ceilings, roof-ceilings, columns, beams, girders, and trusses. This article examines STC as it relates to speech privacy and offers some guidelines for specifying wall construction based on STC ratings. legs. In comparison to another layer of gypsum, the stand-alone STC value of each raw material is similar. This is usu- ally because there is a pronounced dip in the test curve and the STC rating is heavily influenced by a measurement in one fre- quency band. Sound Transmission Characteristics: For gypsum board assemblies with STC ratings, provide materials and construction identical to those test ed in assembly indicated according to ASTM E 90 and classified according to ASTM E 413 by a qualified independent testing agency. a F-IIC and F-STC rating.

The initial specification for the STC 45 wall design called for 3 layers of Type X gypsum board and the STC 50 wall was originally designed using 4 layers of Type X gypsum panels. Sound Transmission Class (STC) STC is a numerical rating of how well a building partition attenuates airborne sound. Lightweight steel studs, such as 25-gauge steel will provide higher STC ratings than wood or S-J structural studs. Classroom doors should be rated as STC-30 or more, and music room doors as STC-40 or more. STC 55 b.
