Three-dimensional headphone sound reproduction based on active noise cancellation

Headphone signal processing systems that are commercially available today are not optimized for the individual listener. This results in large localization errors for most listeners. In the present work, a system is introduced that requires a one time calibration procedure, which can be carried out conveniently by the listener. This system consists of conventional headphones into which small microphones have been mounted. An active noise cancellation method is used to achieve a sound reproduction via headphones, which is as close as possible to a reference loudspeaker setup. The active noise cancellation system is based on adaptive ??lters that are implemented in the frequency domain
