AB  - This report documents the research and prototyping of a new form of acoustical bass absorber. The bass absorber reduces peak and dip frequency response errors caused by interference from naturally occurring standing waves in rooms. The design uses two forms of simple harmonic resonance: pistonic diaphragm resonance and Helmholtz cavity resonance. The pistonic diaphragm resonance is achieved by attaching a rigid planar membrane to metal springs. The Helmholtz cavity resonance is achieved by constructing an enclosed chamber attached to an open tube. Coupling these two dissipation devices led to several-fold improvement in total room mode attenuation.
