Patent ID: 8453788

Claim:
A system for implementing dynamic noise elimination comprising: a system frame including an aperture; a plurality of acoustical sensory devices for monitoring problem frequencies; a plurality of tubes mounted in said system frame aperture; during system operation, said plurality of acoustical sensory devices dynamically detecting problem frequencies; a controller coupled to each of said plurality of tubes for selectively controlling each of said plurality of tubes to be operable open or closed, responsive to said detected problem frequencies; selectively identified ones of said tubes being closed for providing a quarter-wavelength attenuation of an identified problem frequency on a range of frequencies for each of said tubes being closed, based upon a dynamically selected length of each said tube when closed; and selected ones of said tubes being open for allowing airflow; and said controller waiting a set time period, and identifying changes in said detected problem frequencies; and said controller selectively controlling each of said plurality of tubes, responsive to said identified changes in said detected problem frequencies.
