Improving Floor/Ceiling Sound Control in Multifamily Projects: Sound Testing Practices

The sound transmission class (STC) and impact insulation class (IIC) are ASTM-derived single number ratings that try to quantify how much sound a stopped by partition being tested. Laboratory testing involves an ideal setting for the floor/ceiling assembly—it is isolated from the walls, and there are no penetrations for HVAC, plumbing lines, sprinklers, can lights, or electrical boxes. In the field (i.e. F-STC and F-IIC), the floor/ceiling assembly often sits on load-bearing walls, is connected to the structure, and contains many ceiling and floor penetrations for the items just mentioned. Consequently, the code allows for a lower rating for field scores over those in the lab.

The secondary school music suite is comprised of all the rooms or areas used for music education, including rehearsal and practice spaces and storage for instruments, sheet music and apparel. Three key factors should be addressed in music suite design. Good acoustics enable critical listening; an effective space plan speeds traffic flow and logistics; and proper storage safeguards expensive equipment.
