WebThese properties make brick walls effective at resisting the passage of noises commonly in the range of speech, typically measured by the Sound Transmission Class (STC) rating, as well as insulating spaces against low-frequency outdoor noises such as traffic, aircraft, etc., as measured by the Outdoor-Indoor Transmission Class (OITC). WebIt has been well established (ref. 6) that the STC of concrete masonry walls is directly related to wall weight.

WebWhere W = the average wall weight based on the weight of: the masonry units; the weight of mortar, grout and loose fill material in the voids within the wall; and the weight of surface treatments (excluding drywall) and other wall components, lb/ft 2 (kg/m 2).. All other design variables being equal, the STC value of masonry construction increases with increasing … WebSTC was developed primarily for indoor noise sources, such as human speech. Unlike OITC and STC, NRC indicates the ability of a wall to absorb sound, which is useful for controlling sound reverberations within a room. This TEK presents OITC values for a variety of common concrete masonry exterior walls. WebCommon Wall Types and Associated STC Ratings Below is a list of common wall types and their estimated STC ratings that could be used as a guideline for design. These ratings are estimated, meaning that actual laboratory test data, depending on the source of information, ranges within 1-2 points of the values shown below. how is canadian dollar written
