对于“询问者内”，谁可能不熟悉的背景和概念的SEA的好处，本概述打开与讨论的理由使用概率能量模型的高频振动预测，并介绍了传统的SEA的基础上的假设。它比较和联系的模式和行波的方法，讨论了目前实行的SEA的优点和缺点，并指出需要和未来的研究方向。对个人对学科发展的贡献的批判性讨论，只在它们涉及概念、原则或可靠性的具体问题时才提出。SEA的作用，在提供一个框架的实验研究的高频动态行为的系统和解释操作系统上的观察，虽然同样重要，并没有得到充分的解决。也不是具体的实验技术，涉及考虑传感器，空间采样，信号处理，误差分析和数据解释，这需要在自己的权利进行严格的审查。
For the benefit of the 'enquirer within', who may not be familiar with the background and concepts of SEA, this overview opens with a discussion of the rationale for the use of probabilistic energetic models for high-frequency vibration prediction, and introduces the postulate upon which conventional SEA is based. It compares and relates the modal and travelling wave approaches, discusses the strengths and weaknesses of SEA as currently practised and points out needs and directions for future research. Critical discussions of individual contributions to the development of the subject are presented only in as much as they treat specific matters of concept, principle or reliability. The roles of SEA in providing a framework for experimental investigations of the high-frequency dynamic behaviour of systems and in interpreting observations on operating systems, although equally important, are not substantially addressed. Nor are specific experimental techniques which involve considerations of transducers, spatial sampling, signal processing, error analysis and data interpretation, which require a critical review in their own right.
