    • Method and apparatus for estimating the location of an unknown sound source in a structure to be monitored, wherein sounds from at least three known sound sources are detected by a plurality of detectors. At least one of peak value data and signal arrival time data derived from the outputs of the detectors are classified for each of the known sound sources and stored in a storage. Pattern differences from each of the known sound sources to a number of predetermined positions respectively, are calculated to prepare for each of the known sound sources a correspondence table indicating relationships between the calculated pattern difference and the real distances from the known sound source positions to the predetermined positions, the correspondence table being stored in a storage. The pattern differences for each of the known sound source positions are calculated on the basis of the sound signal data derived through detection of a sound from an unknown sound source and the data stored in the storage. The real distances each for the known sound source are read out from the correspondence table on the basis of the calculated pattern differences and displayed on a display device to thereby estimate the location of the unknown sound source.
    • 用于估计要监视的结构中的未知声源的位置的方法和装置,其中来自至少三个已知声源的声音由多个检测器检测。 从检测器的输出导出的峰值数据和信号到达时间数据中的至少一个被分类用于每个已知声源并存储在存储器中。 计算每个已知声源到多个预定位置的图案差异,以便为每个已知声源准备对应表,该对应表指示所计算的图案差异与从已知声源位置到实际距离之间的关系 预定位置,对应表被存储在存储器中。 基于通过检测来自未知声源的声音和存储在存储器中的数据导出的声音信号数据来计算每个已知声源位置的图案差异。 基于计算出的图案差异,从对应表中读出已知声源的实际距离,并显示在显示装置上,从而估计未知声源的位置。
