有关声音暴露的基本概念进行审查，而不广泛依赖于物理声学或心理声学的技术细节。频率和强度的声音，可能会遇到在医院的托儿所进行了说明。声级的非线性特性的例子。增加和减少分贝的复杂性进行了讨论。一些重要的噪音标准进行审查，沿着解释为什么有些声音可能比其他人更烦人。本期的一篇配套文章提供了如何进行声级测量的实用信息。
Basic concepts about sound exposure are reviewed without extensive reliance on the technical details of physical acoustics or psychoacoustics. The frequencies and intensities of sounds that might be encountered in a hospital nursery are described. Examples of the nonlinear properties of sound levels are provided. The complexities of adding and subtracting decibels are discussed. Some important noise standards are reviewed, along with an explanation of why some sounds might be more annoying than others. A companion article in this issue gives practical information on how to make sound-level measurements.
