The application discloses an apparatus that comprises an acoustic sensing system and an analyzer module. The acoustic sensing system is positioned relative to an object, wherein the acoustic sensing system detects acoustic emissions and generates acoustic waveform data for the acoustic emissions detected. The analyzer module is implemented in a computer system that receives load data and the acoustic waveform data for the object, generates a plurality of frequency distribution functions using the acoustic waveform data, and generates a frequency distribution function time evolution image containing a plurality of points of each of the plurality of frequency distribution functions. 本申请公开一种装置，其包括声感测系统和分析器模块。该声感测系统相对于目标放置，其中声感测系统检测声发射并且生成用于检测到的声发射的声波形数据。分析器模块被实施在计算机系统中，该分析器模块接收目标的负荷数据和声波形数据，使用声波形数据生成多个频率分布函数，并且生成包含多个频率分布函数的每一个的多个点的频率分布函数时间演变图像。
