Title:
ACOUSTIC MEASURING DEVICE AND ACOUSTIC MEASURING METHOD
Document Type and Number:
Japanese Patent JP2014095723
Kind Code:
A
Abstract:
To provide an acoustic measurement device and an acoustic measurement method capable of accurately and easily measuring directional information of sound represented by acoustic intensity.
An acoustic measurement device comprises: a sound receiving section 11 for receiving sound by using a unidirectional microphone pair arranged so that directivity is inverted by 180 degrees on a predetermined axis; an arithmetic processing section 12 for performing arithmetic processing of directional information of the sound including an arrival direction of the sound by using output difference of the unidirectional microphone pair; and an output section 13 for outputting the directional information of the sound.
