Acoustic Absorbers And Diffusers - Theory Design ...

: Modern designs, such as Binary Amplitude Diffusers (BAD) , combine these functions—scattering high frequencies while absorbing lower ones to treat a wider spectrum in a single panel. Common Design Types

: These typically use porous materials (like mineral wool or fiberglass) to convert sound energy into heat through friction. Their effectiveness is measured by the Noise Reduction Coefficient (NRC) , where 1.0 represents total absorption. Acoustic Absorbers and Diffusers Theory Design ...

: Instead of removing energy, they scatter it in multiple directions using geometric surfaces. This breaks up strong "specular" reflections that cause phase smearing and flutter echo. : Modern designs, such as Binary Amplitude Diffusers

For those looking to design or build treatments, several mathematical models are standard: : Modern designs
