The use of piezo-electric accelerometers to detect sounds and vibrations emitted from joints and tissues is a significant advance on acoustic detection systems. All possible sources of artefact signal encountered by the vibration emission technique were investigated. A number of errors could be avoided by good technique. All artefact signals were easily distinguished from true vibration emission. As the accelerometer cables were part of the capacitance system it was concluded that other types of accelerometer should be investigated to reduce cable noise.
使用压电加速度计来检测关节和组织发出的声音及振动，这是声学检测系统的一项重大进步。研究了振动发射技术所遇到的所有可能的伪信号源。通过良好的技术可以避免一些误差。所有伪信号都能很容易地与真实的振动发射区分开来。由于加速度计电缆是电容系统的一部分，因此得出结论，应该研究其他类型的加速度计以降低电缆噪声。
