SoundSense Smokes Low Frequency Sound With New Acoustic Chimney

[The following is a release from SoundSense]

July 29, 2008

Acoustic design and engineering firm SoundSense, LLC reveals an innovative new technology and design for an Acoustic Chimney that absorbs, filters, and reduces low frequency sound in a home theater or living area. A sound generating room is encapsulated within an outer acoustic rated perimeter that contains various openings to one or more acoustic duct(s), or "chimney(s)". The acoustic chimney(s) functions as an acoustic waveguide to the open air, or specific location intended to receive the low frequency wave. The chimney may be tuned to transmit defined frequencies. This ground-breaking development allows low frequency sound waves to diffract through the sound generating room (through duct openings), and broadcast through the acoustic chimney. Ultimately, the sound is radiated at a distance outside the source room. The effect is similar to a pressure release valve. The Acoustic Chimney generates effective noise control for the home theater, media room, or any room with excess noise at a reduced cost to standard treatments. The acoustic waveguides may be coupled to tunable passive or active noise mitigation devices such as Helmholtz resonators and low frequency noise sources that utilize phase information. "You'll be astonished by the effectiveness of the Acoustic Chimney," says Bonnie Schnitta, SoundSense LLC president. "We are happy to bring to market acoustic treatment products that can be utilized in every installation that solve sound problems for both the installer and client."
