An acoustic isolation device includes at least one attenuating acoustic scatterer having a plurality of channels. The plurality of channels may include three or more channels. The channels have open ends and terminal ends, wherein the terminal ends of the channels are separated from each other. The at least one attenuating acoustic scatterer has an acoustic monopole response and an acoustic dipole response, the acoustic monopole response and the acoustic dipole response having substantially similar resonant frequencies.
