ISO 22897:2003将隔音值指定给所有透明、半透明和不透明的玻璃产品，这些玻璃产品拟用于建筑物的玻璃组件中，并且作为主要目的或作为补充特性，具有隔音性能。它概述了根据玻璃产品的声学性能对其进行评级的程序，从而能够评估玻璃产品是否符合建筑物的声学要求。对测量数据进行严格的技术分析仍然是一种选择，但ISO 22897:2003旨在推导更简单的性能指标，非专家可以放心地采用这些指标。通过采用ISO 22897:2003的原则，简化了建筑规范和产品规范中声学要求的制定，以满足玻璃的特殊需求。公认ISO 140的声学测试程序-1和ISO 140-3仅与窗格玻璃及其组合完全相关。尽管应尽可能严格遵循相同的原则，但由于其他玻璃类型的结构更笨重，不可避免地需要做出一些妥协。第4条给出了如何调整这些材料以包括玻璃块、砖、结构玻璃、槽形玻璃和铺路机的指南。

ISO 22897:2003 assigns sound insulation values to all transparent, translucent and opaque glass products that are intended to be used in glazed assemblies in buildings, and which exhibit properties of acoustic protection, either as a prime intention or as a supplementary characteristic.It outlines the procedure by which glass products can be rated according to their acoustic performance, which enables assessment of compliance with the acoustic requirements of buildings.Rigorous technical analysis of measurement data remains an option, but ISO 22897:2003 is intended to enable the derivation of simpler indices of performance, which can be adopted with confidence by non-specialists.By adopting the principles of ISO 22897:2003, the formulation of acoustic requirements in building codes and of product specifications to satisfy particular needs for glazing is simplified.It is recognized that the acoustic test procedures of ISO 140-1 and ISO 140-3 relate fully only to glass panes and their combinations. Although the same principles should be followed as closely as possible, it is inevitable that some compromises are necessary, because of the bulkier construction of other glazing types. Guidelines on how to adapt these to include glass blocks, bricks, structural glazing, channel-shaped glass and pavers are given in Clause 4.
