Abstract
A signal processing method includes: receiving, by a first reception unit, an acoustic signal transmitted via a first transmission path, the acoustic signal received by the first reception unit being a first acoustic signal; receiving, by a second reception unit, the acoustic signal transmitted via a second transmission path different from the first transmission path, the second transmission path having a longer delay time for transmission than the first transmission path, and the acoustic signal received by the second reception unit being a second acoustic signal; calculating, by a delay amount calculation unit, a transmission delay amount that is a relative delay amount between the first acoustic signal and the second acoustic signal; and delaying, by a delay amount addition unit, the first acoustic signal based on the calculated transmission delay amount and outputting the delayed first acoustic signal.
