Sound travels through both the air and structure, and both paths must be considered when designing sound isolating walls and ceilings. To eliminate air borne sound all air paths between the areas must be eliminated. This is achieved by making seams airtight and closing all sound leaks. To eliminate structure-borne noise one must create isolation systems that reduce mechanic… WebAug 15, 2011 · Most ICFs with a six-inch concrete core (10- or 11-inch ICF wall) advertise STC ratings of 50 to 55. A Sound Transmission Class (STC) rating is a measure of how much sound travels from one side of the wall to the other, and is measured in decibels. Uninsulated 2×4 wood stud walls have an STC rating of about 33.
