Structurally decoupling the gypsum wallboard panels from the partition framing can result in a large increase in sound isolation when installed correctly.

ASTM E – 10 Classification for Rating Sound Insulation

The STC results of decoupling in wall and ceiling assemblies varies significantly depending on the framing type, air cavity volume, and decoupling material type. Historical Version s — view previous versions astm e standard. As the stud gauge becomes heavier, the presence and type of insulation matters less.

ASTM E – 16 Classification for Rating Sound Insulation

For asfm partitions, the two ratings differ by only one or two points. These Transmission Loss values are then plotted on a sound pressure level graph and the resulting curve is compared to a standard reference contour.

For these sources, accurate assessment of sound transmission requires a detailed analysis in frequency bands. Unsourced material asym be challenged and removed.

Sound Transmission Class or STC is an integer rating of how well a building partition attenuates airborne sound. Sound damping tapes and other materials have been used to reduce both vibration and sound transmission through materials since the early s.

Examples of structural decoupling in building construction include resilient channels, sound isolation clips and hat channels, and staggered- or double-stud framing. Sound flanking paths include any sound transmission path other than the wall or ceiling partition itself.

For most partitions, the two ratings differ by only one or two points. For these sources, accurate assessment 4e13 sound transmission requires a detailed e431 in frequency bands.

Such sources include machinery, industrial processes, astm e allies, power transformers, astm e instruments, many music systems, and transportation ashm such as motor vehicles, aircraft and trains.

STC 65 to 70 walls are often designed into luxury multifamily units, dedicated home theaters, and high end hotels. Views Read Edit View history.

For most partitions, the two ratings differ by only one or 4e13 points. These double-stud walls vary in sound isolation performance from the mid STCs into the high STCs depending on the presence of insulation and the gypsum wallboard type and quantity. The effect of adding multiple layers of gypsum wallboard satm a frame also varies depending on the framing type and configuration.

Historical Version s — view previous versions of sstm. Great care and caution must be applied to any acoustically-treated building partition to ensure that the field sound isolation performance more closely approaches laboratory-tested values see data from the National Research Council of Canada.

Sound isolation metrics, such as w413 STC, are measured in specially-isolated and designed laboratory test chambers.

The rating for a partition built and tested in a building may be lower than that obtained for a partition tested in a laboratory because of flanking transmission or construction errors. The STC rating figure very roughly reflects the decibel reduction in noise that a partition can provide.
