Title: Sound Transmission Loss Through Concrete and Concrete Masonry Walls

Abstract:Many building codes require minimum sound transmission loss values, expressed as sound transmission class (STC), OF 45 TO 50. Tests of sound transmission loss were made on 8 in. (203 mm) thick concrete masonry walls and on 6 and 8 in. (152 and 203 mm) thick cast concrete walls. These walls were finished with materials intended to increase their sound transission loss. Using furring, acoustic insulation, and wallboard attachments, STC values up to 59 and 63 were obtained for the masonry and cast concrete walls, respectively. Selected STC values, reported by other investigators, for a variety of walls are included for reference.
