Stc concrete walls.

The calculation in tms 0302 is based on a best fit relationship between concrete masonry wall weight and stc based on a wide range of test results. The stc is measured by positioning a representative sample of the building material midway in an acoustical chamber dividing the chamber in half or into two rooms. Usg area separation walls achieve up to 60 stc offer 2 hr. Sound transmission class the decibel db is used to express sound intensity or loudness the more intense a sound the higher the db level the sound transmission class stc is a numerical rating of the ability of a wall floor ceiling assembly or any other building element such as a door or window to minimize sound transmission.

The stc of a wall is determined by comparing sound transmission loss stl values at various frequencies to a standard contour. When the mass of a barrier is doubled the isolation quality or stc rating increases by approximately 5 db which is clearly noticeable. Determining sound transmission class stc for concrete masonry. How soundproof is concrete.

1 contains procedures for determining stc values of concrete masonry walls. According to the standard stc can be determined by field or laboratory testing in ac cordance with standard test methods or by calculation. Stc ratings for masonry cmu walls is based on weight of the block and whether the cells are filled or not and what material it is filled with. Stc 20 50 234w eqn.

Estimated stc ratings for cmu walls the stc rating of a cmu wall can be estimated based on its weight using the following formula. Drywall and plaster are simple to affect and you can produce holes with minimal effort. When you tap on your walls a concrete wall will not echo nor be easy to move or impact. It s sturdy and provides withstanding use over long periods of time.

Sound transmission class stc provides an estimate of the acoustic performance of a wall in certain common airborne sound insulation applications. All too often this plenums and suspended ceilings unbaffled ducts window to window outdoors common heating units transoms and air grilles unblocked joist spaces uncaulked wall perimeters ducts piping and fixtures masonry joints. Concrete is the standard building material for a reason. The stc can be used to measure sound absorption for both external building walls and internal walls in single and multifamily structures.

For example a thick concrete wall will block more sound than a thin gypsum 2x4 wall. Mass is commonly added to existing walls by adding additional layers of gypsum.
