Abstract
A sound isolation device includes at least one degenerate acoustic scatterer having a plurality of channels. The plurality of channels may include three or more channels. The channels have an open end and a terminal end, wherein the terminal ends of the channels are separate from one another. The at least one degenerate acoustic scatterer has an acoustic monopole response and an acoustic dipole response that have a substantially similar resonant frequency.
