Abstract
A feedforward active noise cancellation system comprising one or more reference microphones, one or more loudspeakers, one or more error microphones, a first filter, and a second and adaptive filter. The first filter is configured to filter a first input signal to minimize a residual error. The second and adaptive filter comprises a linear predictor of speech. The second and adaptive filter is configured to filter a second input signal based on predicted speech to compensate for a processing delay and a second propagation delay exceeding a first propagation delay.
