Determining sound transmission class stc for concrete masonry sound transmission class stc provides an estimate of the acoustic performance of a wall in certain common airborne sound insulation applications.

Sound transmission class ratings for concrete masonry walls.

Sound transmission class ratings for concrete masonry walls introduction. Determining sound transmission class stc for concrete masonry. 1 contains procedures for determining stc values of concrete masonry walls. The stcof a wall is determined by comparing sound transmission loss stl values at various frequencies to a standard contour.

Stc ratings for concrete masonry walls are determined using standard method for determining the sound transmission class rating for masonry walls tms 0302 ref. In general the heavier a concrete masonry wall is the more effectively it will block sound transmission. To achieve performance compa rable to a masonry wall a stud. Thus heavier walls have a higher rating.

Stc sound transmission class rating w wall weight based on the average density of the masonry units the weight of mortar grout loose fill materials and the weight contributed by surface treatments. Determining sound transmission ratings for masonry walls tms 0302 ref. The calculation in tms 0302 is based on a best fit relationship between concrete masonry wall weight and stc based on. Concrete masonry walls are.

According to the standard stc can be determined by field or laboratory testing in ac cordance with standard test methods or by calculation. The sound transmission class stc is a single number rating of a material s or an assembly s ability to resist airborne sound transfer at the frequencies 125 4000 hz. Stc is highly dependant on the construction of the partition. Sound transmission class stc provides an estimate.

In general a higher stc rating blocks more noise from transmitting through a partition. The national concrete mason ry association ncma provides t h e f o l l o w i n g e q u a t i o n t o e s t i mate the stc for concrete ma sonry walls based on their weight. 2 provides stc ratings for com mon wall assemblies. Unwanted noise can be a major distraction whether at school work or home.
