Abstract
A sound isolating wall assembly includes a plurality of walls defining a space between the plurality of walls. At least one acoustic scatterer is disposed within the space between the plurality of walls. The at least one acoustic scatterer has an opening and at least one channel. The at least one channel has a channel open end and a channel terminal end, with the channel open end being in fluid communication with the opening.
Claims19
A sound isolating wall assembly comprising:
- a plurality of walls, the plurality of walls defining a space between the plurality of walls;
- at least one degenerative scatterer located within the space defining the plurality of walls;
- the at least one degenerative scatterer having an opening and a plurality of channels, the plurality of channels each have a channel open end and a channel terminal end, the channel terminal ends being separate from each other;
- wherein the plurality of channels extend parallelly along the length of the at least one degenerative scatterer;
- and
- wherein the at least one degenerative scatterer has an acoustic monopole response and an acoustic dipole response, wherein the acoustic dipole response and the acoustic monopole response of the at least one degenerative scatterer have a resonant frequency that is substantially similar.
