Japanese Patent JP7136445
Kind Code:
B2
Abstract:
To increase the accuracy of measuring acoustic information.SOLUTION: An acoustic information measuring device comprises: a plurality of sound collection units for collecting arriving sounds and having a prescribed directivity characteristic; and an acoustic information calculation unit for calculating acoustic information that pertains to sounds on the basis of a signal generated for each sound collection unit as sounds are collected by a sound collection unit in accordance with the directivity characteristic of the sound collection unit, and sound characteristic represented for each sound collection unit by a set of coefficients of first and second terms when a signal is represented by a first term that represents a particle speed component that is the component in a specific direction of particle speed of a medium that transmits a sound and a second term that represents the pressure of a sound.SELECTED DRAWING: Figure 1
