1. A computer-implemented method for automatically optimizing a hybrid active noise cancellation system, the hybrid active noise cancellation system comprising a feedback filter and a feedforward filter, the method comprising:
optimizing the feedback filter prior to optimizing the feedforward filter, wherein optimizing the feedback filter comprises:
i) estimating a second frequency response of an adaptive noise cancellation system at a user's ear, the second frequency response being due to the feedback filter;
ii) determining an adjustment to be applied to a feedback filter transfer function based on the second frequency response; and
iii) adjusting the feedback filter transfer function; and optimizing the feedforward filter, thereby optimizing the hybrid active noise cancellation system, wherein optimization of the feedforward filter is dependent on the feedback filter.
