资源简介：
Surface impedance measured in a Kundt's tube of different porous multilayer configurations. Each file contains the frequency values and the complex-valued surface impedance with in a rigid-backed configuration or backed by an air gap of 20mm. The thickness of sample 1 (recycled foam) is 32mm and the thickness of sample 4 (fibrous material) is 45mm.<br>
