Abstract
A sound pickup device includes a processor with hardware. The processor calculates a first relational expression between acoustic filter factors of acoustic filters applied to microphone acquisition signals acquired by two or more microphones, based on a multiplication factor at a sensitization control point with high sound pressure sensitivity by the two or more microphones and a transfer function between each of the two or more microphones and the sensitization control point. The processor calculates a second relational expression between the acoustic filter factors, based on information of a frequency of a sound source and an interval between the two or more microphones. The processor calculates each of the acoustic filter factors, based on the first relational expression and the second relational expression.
