The above sound absorption data was determined by tests conducted at Geiger and Hamme Acoustical Laboratory in strict compliance with ASTM C423 specifications. Actual installed performance may vary.

       

Left Hand and Right Hand Units

For situations requiring a full core for vertical reinforcement, SOUNDBLOX units with open cavities on either the left- or right-hand side are available. When used in conjunction with standard SOUNDBLOX units, reinforcing boards and grout can be incorporated easily and efficiently. SOUNDBLOX units have been approved for use in reinforced masonry construction and are allowed 90% of the hear value of ordinary hollow concrete block.

Type RSC/RF

Special SOUNDBLOX unit providing the sound absorption of Type RSC units. Incorporates a metal septum and filler, and two additional large, straight through cavities allowing specification of this unit in applications requiring vertical reinforcing, thermal insulation or accommodations for vertical conduits and/or pipes. Available in 8″, 10″ and 12″ thickness.
