Abstract
An acoustic device and a method for altering sound. The acoustic device includes an architectural structure having a solid body. The architectural structure is adapted to be mounted on a wall of a room. The solid body has a channel therethrough to define a cavity therein. The channel is configured to alter sound waves incident on the acoustic device.
Claims42
An acoustic device for altering sound, comprising:
- an architectural structure constructed to be mounted on a wall of a room, the architectural structure having a solid body defining a channel therethrough, the channel having a volume (V) and a diameter (d), the solid body having a thickness (z) defined by a maximum distance between an external surface of the solid body and an interface between the solid body and the channel;
- wherein the solid body is configured to alter incident low-frequency through high-frequency audible sound waves received by the acoustic device in a manner that includes at least one of absorbing, reflecting, diffracting, or diffusing the incident sound waves;
- and
- the channel of the acoustic device absorbs incident sound waves received by the acoustic device, and has an absorbing frequency (fH) determined by the equation:
