Mechanical Fault Sound Source Localization Estimation in a Multisource Strong Reverberation Environment

Table 1

Localization results under different reverberation times.

Reverberation time (s)	Sound source	True sound source location (m)	Localization results (m)	Localization distance error (m)
0.2	Fault source 1	(−0.3, 0.3)	(−0.312, 0.308)	0.014
	Fault source 2	(0.3, 0.3)	(0.290, 0.310)	0.014
	Fault source 3	(0.5, 0.2)	(0.494, 0.210)	0.012
0.5	Fault source 1	(−0.3, 0.3)	(−0.294, 0.310)	0.012
