Abstract
An extended bandwidth folded well diffusor extends the diffusion bandwidth of a shallow, asymmetric diffusor by incorporating maximum-depth, folded L-shaped, half-width wells on both ends (sides) of a diffusor, thus providing increased maximum well depth without increasing the physical depth of the diffusor. When the inventive diffusor is placed in an array, the folded L-shaped, maximum-depth, half-width end wells form a novel T-shape, which offers a favorable impedance lowering the resonant frequency, thus extending the diffusor diffusion bandwidth. T-shaped recesses may also be located within a single diffusor. The front surface of the diffusor may be flat or curved or angled.
Claims20
An acoustical device, comprising:
- a) at least one diffusor having a front face and at least one side face;
- b) said front face having a plurality of wells adapted to diffuse sound waves;
- c) said at least one diffusor including at least one forward facing T-shaped sound diffusing recess, said recess being defined by a first leg opening at said front face and leading rearward to a substantially perpendicular second leg defining a chamber.
An acoustical device, comprising:
- a) a plurality of diffusers, each having a front face and at least one side face;
- b) said front face of each diffusor having a plurality of wells adapted to diffuse sound waves;
- c) said diffusers including at least one forward facing T-shaped sound diffusing recess, said recess being defined by a forwardly open first leg leading rearward to a substantially perpendicular second leg defining a chamber.
