Active Noise Control with Adaptive Lattice Filters View and Print for better resolution in PDF format. New adaptive ANC algorithms based on recursive least-squares ( RLS lattice filters produce faster adaptation (convergence) than standard algorithms based on stochastic-gradient (LMS) adaptation. RLS lattice filters produce true minimum-variance performance in the presence of broad-band noise. Properties of Lattice Filters Fast real-time computation Numerically stable Excellent VLSI realization Experimental Active Noise Control in a One-Meter Box Broadband noise is generated by an external speaker and sensed by an external microphone. An internal speaker (actuator) is driven by the ANC computer. Sample-and-hold rate: 2500Hz Adaptive Lattice Filter of order 14 selects control gains to minimize noise at internal microphones. Lattice Filter converges to near-optimal gains in 0.1 sec, optimal gains in 0.25 sec. S.-J. Chen and J. S.

Active noise control - Your Art History Reference Guide! Art History Search Art History Browse News Gallery ... Noise Active noise control Active noise control (also known as noise cancellation or antinoise ) is a method for preventing unwanted sound . Sound consists of vibrations in the air , which can be represented as a wave . If a speaker emits a sound whose wave has the same amplitude and the exact opposite polarity to the original sound, the waves cancel out and the result is no sound at all. A computer analyses the waveform of the background aural or nonaural noise interference . This waveform has identical or directly proportional amplitude to the waveform of the noise, but its phase is the opposite. This creates destructive interference that reduces the amplitude of the perceived noise. This method differs from passive noise control methods ( sound proofing ) in that a powered system is involved, rather than unpowered methods such as insulation , sound-absorbing ceiling tiles, or automobile mufflers The advantages of active noise control methods compared to passive ones are: they are more effective at low frequencies they are less bulky, something valuable on aircrafts
