Multi-Tone Active Noise Equalizer With Spatially Distributed User-Selected Profiles

In this work we propose a multi-channel active noise equalizer (ANE) that can deal with multi-frequency signals and assigns simultaneously different equalization gains to each frequency component at monitoring sensor. For purpose, state pseudo-error signal for sensor of the ANE, which has be cancelled out in order get desired profiles. Firstly optimal analytic solution ANE filters case single-frequency is provided, an adaptive algorithm based on Least Mean Squared (LMS) proposed same case. We also show strategy reaches theoretical steady state. Secondly, equivalent approach two alternatives: common all frequencies, frequency. The solutions control have been developed both alternatives. Finally, ability achieve user-selected profiles locations validated by their transfer functions simulations.
