Sound Transmission Class (or STC) is an integer rating of how well a building partition attenuates airborne sound. In the US, it is widely used to rate interior partitions, ceilings, floors, doors, windows and exterior wall configurations.
The Sound Reduction Index is expressed in decibels (dB). It is the weighted sound reduction index for a partition or single component only. This is a laboratory-only measurement, which uses knowledge of the relative sizes of the rooms in the test suite, and the reverberation time in the receiving room, and the known level of noise which can pass between the rooms in the suite by other routes ...
It is occasionally used to rate floor coverings. [7] NRC is intended to be a simplified acoustical rating of room construction and finish materials when the acoustical objectives of the space are less than sensitive. The NRC average is rounded to the nearest 0.05 due to a typical lab repeatability of ±0.05 for 2 standard deviations.
Adding one layer of Acoustiblok to a standard metal stud gypsum board interior wall has the potential to increase its STC rating. Double steel stud partition walls, faced with single layers of drywall and containing fiber-glass insulation and Acoustiblok, can achieve an STC of up to 66, according to the manufacturer.
The article states that STC ratings before 1999 would be unreliable, however the chart of values was taken from a book published in 1994. —Preceding unsigned comment added by 204.128.192.3 ( talk ) 20:58, 30 September 2009 (UTC) [ reply ]
Fire resistant – flame spread 5, smoke spread 0 (ASTM-E-84) – will not smoke at all upon direct contact with flame and is a two-hour firewall at a 3.5 in (89 mm), or normal 2 in × 4 in (51 mm × 102 mm) stud wall, application per ASTM E-199. Great for sound deadening, STC 53 (ASTM E413-73); does not echo like other foams.
In mathematics, the floor function is the function that takes as input a real number x, and gives as output the greatest integer less than or equal to x, denoted ⌊x⌋ or floor(x). Similarly, the ceiling function maps x to the least integer greater than or equal to x , denoted ⌈ x ⌉ or ceil( x ) .
Various sized cuts of 1 ⁄ 2 in (13 mm) drywall with tools for maintenance and installation . Drywall (also called plasterboard, dry lining, [1] wallboard, sheet rock, gib board, gypsum board, buster board, turtles board, slap board, custard board, gypsum panel and gyprock) is a panel made of calcium sulfate dihydrate (), with or without additives, typically extruded between thick sheets of ...
