Sound Attenuation - Managing Sound Transfer for Code and for Client

Tue, 11/05/2013 - 15:23

Sound attenuation for floor/ceiling assemblies may be required to attain code ratings or to mitigate sound for a client. The best practice in residential, multi-family and light commercial applications is to have the assembly evaluated by one of several testing methods. The common methods used are: field or lab testing, software modeling and estimating. Each method offers a different level of accuracy and cost. Usually these services are performed by an “Acoustical Consultant” to provide STC and IIC ratings. The higher the number, the quieter the floor/ceiling assembly.
