Active noise control method and apparatus includes a feedforward and feedback controller

An active noise control device for reducing noise from a noise source receives a microphone that detects noise generated by the noise source, and a noise signal of noise detected from the microphone, and reduces noise from the noise source. And a generalized finite impulse response (FIR) filter for generating a control signal. The speaker generates sound based on the control signal from the generalized FIR filter that cancels noise from a noise source. [Selection] Figure 1
