摘要

The authors have previously studied the acoustic properties of membrane materials for building purposes and doubleleaf membrane structures of various configurations made of these materials [1–7]. Membrane materials exhibit different acoustical properties depending on their acoustic permeability. Therefore, different combinations of permeable and impermeable membranes produce various double-leaf membrane structures with different acoustic properties. Doubleleaf membranes with only impermeable leaves [5] and with impermeable and permeable leaves [6,7] have been investigated. However, those with two permeable leaves were only studied under the normal incidence condition [8,9], and their acoustical properties for diffuse field incidence should be studied.
