Acoustic panels, apparatus and assemblies with airflow-resistive layers attached to sound incident surfaces

An acoustic panel includes a main body portion having a substantially planar front surface for orientation toward a sound source and an opposite, substantially convoluted rear surface. An airflow-resistive layer of material is secured to the planar front surface in face-to-face contacting relationsh...

description	An acoustic panel includes a main body portion having a substantially planar front surface for orientation toward a sound source and an opposite, substantially convoluted rear surface. An airflow-resistive layer of material is secured to the planar front surface in face-to-face contacting relationship. The airflow-resistive layer of material may have a specific airflow resistance of between about 50-20,000 mks rayls, and may be configured to attenuate sound at one or more predetermined frequencies. A depth of convolution of the rear surface is between about forty percent to about seventy-five percent (40%-75%) of a thickness of the main body portion.
