Design of noise reduction headphone

This paper designs and implements a noise reduction headphone using adaptive feedback active noise control (ANC). The position of the error microphone inside ear-cup was studied and determined experimentally, and music signals were used for adaptive modeling of the secondary path. The designed ANC headphone was implemented using a digital signal processor for real-time testing. Experimental results show the proposed headphone achieves higher noise cancellation especially at low-frequencies than a commercial available ANC headphone.
