Document Type and Number:
Japanese Patent JP7215212
Kind Code:
B2
Abstract:
To provide an acoustic characteristic measuring device which accurately measures the acoustic characteristic of a measurement object sound emanated from a measurement object.SOLUTION: Provided is an acoustic characteristic measuring device, comprising: a measurement control unit for transmitting, to a stage, a control signal for controlling the drive of a stage capable of moving an installed measurement object and microphone while their optional relation is fixed; a collected-sound signal receive unit for receiving a collected-sound signal from the microphone; a Fourier transform unit for Fourier-transforming the collected-sound signal received by the collected-sound signal receive unit and generating a frequency spectrum; a measured signal extraction unit for extracting a measured signal based on a measured object sound from the measurement object using a plurality of frequency spectra generated by the Fourier transform unit on the basis of the collected-sound signal received along with the movement of the stage; and a signal transmission unit for transmitting the measured signal extracted by the measured signal extraction unit.SELECTED DRAWING: Figure 1
