Kind Code:
A1
Abstract:
The present invention promotes additional improvements in usability. A signal processing device (10) is provided with: an acquisition unit (111) for acquiring acoustic characteristics inside a user's ears that are shut off from an external environment; an NC filter unit (1122) for generating data of sound having a phase opposite to that of environmental sound that leaked into the user's ears; a correction unit (1123) for correcting the data of the sound by using a correction filter; and a determination unit (1121) for determining the filter coefficient of the correction filter on the basis of the acoustic characteristics.
