Abstract
A method, system and computer program product are provided for implementing dynamic noise elimination. A system frame includes a plurality of acoustical sensory devices monitoring the system for problem frequencies. The system frame includes a plurality of tubes. When the tube is open, airflow is allowed. When identified tubes are closed, quarter-wavelength attenuation is provided for a frequency in a range of frequencies, based upon a length of the tube when closed. Each of the plurality of tubes is selectively controlled to be operable open or closed at a particular length, responsive to identified problem frequencies.
