建筑物结构噪声的测量和预测方法有了稳步发展，特别是在过去的二十年里。在提出和评估这些方法时，一个主要的考虑因素是准确性和简单性之间可能的权衡。结构声传播是一个比空气声传播更复杂的过程，但从业者寻求预测前者的方法，这是简单的，因为后者。本文叙述了建筑物中多接触源的研究。这项研究集中在测量和计算程序的来源和计算程序的接收器结构，特别是轻型建筑元素。虽然这项研究并不详尽，但研究结果指出了简化方法的局限性，特别是减少数据集和计算工作量可能导致的不确定性，以及简化假设造成的差异。
There has been a steady development of methods of measurement and prediction of structure-borne noise in buildings, particularly over the last two decades. In proposing and evaluating these methods, a major consideration has been the likely trade-off between accuracy and simplicity. Structure-borne sound transmission is a more complicated process than airborne sound transmission, but practitioners seek methods of prediction for the former, which are as straightforward as for the latter. In this paper a description is given of a study of multi-contact sources in buildings. The study concentrates on measurement and calculation procedures for sources and calculation procedures for receiver structures, particularly lightweight building elements. Although the study is not exhaustive, the findings point to the limitations of simplified methods, specifically the uncertainties likely as a result of reducing the data sets and computational effort, and the discrepancies resulting from simplifying assumptions.
