Abstract: A signal processing device includes one or more filter processors that perform sound localization processing of an input acoustic signal and generate output signals; a coefficient setter that sets, for the filter processors, a plurality of filter coefficients for use in the filter processors; an output data selector that selects, out of the output signals subjected to the sound localization processing by the filter processors, output signals to be output to a left speaker and a right speaker; a time measurer that monitors a time for switching the output signals; and a controller that causes the output data selector to select the output signals in accordance with the time for switching the output signals. The plurality of filter coefficients include filter coefficients generated under a plurality of hearing conditions.
