NRC (Noise Reduction Coefficient) is a standard measurement for a materials acoustical absorption ranging from (no absorption) to (total absorption)CAC (Ceiling Attenuation Class) is a standard measurement of a ceiling systems ability to block sound between two closed spaces.

The soft panel edges also have the ability to improve the acoustical performance due to what is termed the edge effect that is to say the soft edges will also allow acoustical absorption where the panels are separated with a space between the panelsA ×× panel in effect measures × of absorptive surface but the

The proposed panel exhibited superior energy absorption capability compared with a conventional honeycomb sandwich panel under dynamic crushingIn particular, the SEA of the proposed panel increased by and , respectively, compared with that of honeycomb sandwich panels with the same thickness core or the same volume core.
