Time/Frequency Response of a Room with Active Acoustic Absorption

Decay spectra are presented which describe the control of normal modes of an enclosed sound field using active absorbers. The visualization techniques are introduced in the context of a resonant waveguide and extended to investigate the acoustics of a small reverberant room. Results demonstrate that active absorbers offer a practical solution to the problems introduced by discrete low-frequency modes.
