| 摘要 |
A vehicular active vibratory noise control apparatus includes an adaptive notch filter (second control signal generating unit) for generating a corrected error signal representative of a road noise only by removing the component of a rotational frequency (the component of an engine muffled sound) from an error signal, generates a first control signal from the corrected error signal and a reference signal, and reduces the component of the rotational frequency (engine muffled sound) at a position where a microphone is located (evaluating point).
