Noise measurement method , noise measuring device , and noise measurement program

摘要

PROBLEM TO BE SOLVED: To provide a noise measurement method, noise measurement device, and noise measurement program for measuring a radiated noise accurately in a short time.;SOLUTION: A noise measurement device calculates each time-domain spectrum of a noise in a focused frequency band; calculates an average spectrum in the focused frequency band; extracts, on the basis of the average spectrum, frequency points at the maximum noise levels in a plurality of respective divided frequency bands into which the focused frequency band is divided; measures noise levels at the extracted frequency points at the maximum noise levels in the plurality of respective divided frequency bands; and sets the maximum value among the measured plurality of noise levels as a noise level in the focused frequency band.;COPYRIGHT: (C)2013,JPO&INPIT
