摘要

Active noise control (ANC) is the the acoustic reduction of noise by introducing a corresponding anti-phase sound wave which destructively interfere with the unwbted nose.many ANC systmes utilize two or mnore snesors.An upstream measurement of the noise field is used to input to an adaptive filter which is adjusted baeed on the measurement of the downstream cna celed field.A difficulty in multiple sensor systme is that htere is typical an acoustic feedback from the canacelign nosie source to the upstream sensor.
