Stability and sensitivity analyses for diffusers with single and multiple active elements (2005)
Journal Article
Avis, M., Xiao, L., & Cox, T. (2005). Stability and sensitivity analyses for diffusers with single and multiple active elements. Journal of the Audio Engineering Society, 53(11), 1047-1060

In comparison to active absorbers, active diffusers have more complicated target impedance functions, a smaller region of stable control, and are more sensitive to control impedance errors. The issues of stability and sensitivity are analyzed theoret... Read More about Stability and sensitivity analyses for diffusers with single and multiple active elements.

A stable transient BEM for diffuser scattering (2005)
Presentation / Conference
Hargreaves, J., & Cox, T. (2005, October). A stable transient BEM for diffuser scattering. Presented at 150th Meeting of the Acoustical Society of America, Minneapolis

Boundary Element Methods (BEM) may be used to model scattering from hard rigid surfaces such as diffusers. They have the advantage over volumetric methods that only the surface need be meshed and the surface velocity potential found. Unlike the mor...

Active diffusers : some prototypes and 2D measurements (2005)
Journal Article
Xiao, L., Cox, T., & Avis, M. (2005). Active diffusers : some prototypes and 2D measurements. Journal of Sound and Vibration, 285(1-2), 321-339. https://doi.org/10.1016/j.jsv.2004.08.031

Diffusing devices are used to improve room acoustics in a wide variety of applications. The dispersion generated by current diffuser technologies is often limited to mid-to-high frequencies because low-frequency diffusers are usually too large to be...
