摘要：
Disclosed herein is a noise reducing device (20) comprising:
a sound collecting section (21) for collecting sound and outputting a noise signal; a noise reducing audio signal generating section (23) for generating a noise reducing audio signal on the basis of said noise signal and a predetermined noise reducing characteristic; an electric-to-acoustic converting section (11) for acoustically reproducing sound on a basis of said noise reducing audio signal; a switching section (25) for switching the noise reducing characteristic from one noise reducing characteristic to another noise reducing characteristic; and a control section (2325) for controlling said switching such that the generation of said noise reducing audio signal is stopped for a predetermined period of time between the application of said one noise reducing characteristic and said another noise reducing characteristic.
