Sound transmission through periodically framed parallel plates Available to Purchase

The problem of transmission of a plane sound wave through two infinite parallel plates connected by identical periodically spaced frames is solved. Fluid loading within and without the cavity space is taken into account. Numerical results are presented corresponding to a standard double‐walled partition. The strengths of the two parallel transmission paths, i.e., the structural path through the studs and the airborne path through the cavity space, are compared.
