Abstract:
Disclosed are a method for enhancing noise reduction amount of a feedback active noise reduction headphone and active noise reduction headphones. The method includes: arranging a noise reduction microphone of the feedback active noise reduction headphone at a position away from directly in front of a loudspeaker; and adjusting a relative position between the noise reduction microphone and an ear canal opening of a wearer, and enabling an open-loop transfer function at the ear canal opening L 2 (s 0 ) and an open-loop transfer function at the noise reduction microphone L 1 (s 0 ) to satisfy a relation of |L 2 (s 0 )|>|L 1 (s 0 )|, to enhance an actual noise reduction amount at the ear canal opening.

Claim (Index 6):
The method according to  claim 5 , wherein the damping mat is formed by filling the earmuff with felted wool or compressed sponge.
