  • Patent number: 9121752
    Abstract: Provided is an acoustic measurement device capable of reducing the number of microphones while solving a problem of the dependency of interval between microphones on the frequency. The acoustic measurement device comprises a sound reception section (10) and a calculation section (20). The sound reception section includes a plurality of unidirectional microphones. The plurality of microphones of the sound reception section (10) are arranged such that the total sum of the unit vectors each facing the maximum sensitivity direction of the microphone is zero. The calculation section (20) calculates a particle velocity vector or acoustic intensity by multiplying respective unit vectors by measurement values of each of the plurality of microphones of the sound reception section and calculates acoustic information by vector-synthesizing the results.
