Acoustic Absorbers And Diffusers Theory Design ... Page
For those looking to design or build treatments, several mathematical models are standard:
: These use a grid of blocks at different heights to scatter sound both horizontally and vertically, creating a hemispherical pattern. 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 For those looking to design or build treatments,
: Based on number theory, these use wells of varying depths to provide broadband scattering. You can use tools like the QRD Diffuser Calculator to determine well depths for specific frequency ranges. You can use tools like the QRD Diffuser
The fundamental difference lies in how they handle sound energy:
: Simple frames filled with dense insulation. Efficiency depends on thickness; thicker panels are required to absorb low-frequency standing waves.
: 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.
