摘要： A method and apparatus for utilizing the sound and pattern recognition capabilities of the human auditory system, which takes information contained in typical instrumentation signals in the form of amplitude, frequency, and time characteristics, and converts this information into sound qualities and characteristics which are recognizable by the human listener. The method and apparatus digitizes the analog amplitude, frequency, and time information, and selects appropriate sound characteristics into which it may encode this information in standardized form that is recognizable to the human listener. The method allows for the testing or inspection of materials using nondestructive evaluation techniques in a manner that allows the tester to interpret the information provided by the testing system, either exclusively through his auditory senses, or through his auditory senses in conjunction with visual indicators.
摘要翻译：一种利用人类听觉系统的声音和模式识别能力的方法和装置，其以振幅，频率和时间特征的形式获取典型仪器信号中包含的信息，并将该信息转换为可识别的声音质量和特征由人的听众。该方法和装置对模拟幅度，频率和时间信息进行数字化，并且选择合适的声音特征，其中可以以人类听者可识别的标准形式对该信息进行编码。该方法允许使用非破坏性评估技术对材料进行测试或检查，使得测试者能够通过他的听觉感觉或通过与视觉指示器的听觉来解释由测试系统提供的信息。

摘要： An electromagnetic inspection system for detecting, in-situ, the location and character of flaws in a relatively long, thick-walled small bore tube of a heat exchanger wherein a resultant magnetic field is induced in the wall of the tube of selected direction and magnitude by the vector addition of the magnetic fields produced by two magnetic field generators, at least one of which is carried by a scanner for traversing the tube and having an array of sensors mounted in close proximity to the wall of the tube generating a unique signal as the scanner passes a flaw in the tube.
