本文件描述了住宅声学分类的标准和程序。 本文件的目的是让开发商更容易指定住宅的声学质量等级，帮助用户和建筑商了解声学条件，并定义增加的声学质量。该文件还可作为描述现有住房质量的通用工具，包括对装修前后的声学质量进行分类的规定。通过对住宅声学质量的理解，住宅声学性能的质量通常包括在建筑法规中，例如对邻近房屋和道路交通的隔音以及来自服务设备的声音。 住宅内部的隔音和室内声学不包括在定义的声学类别中。 本文件在一个国家不具有法律地位，除非由该国当局决定。然而，本文件的另一个目的是帮助国家当局和标准化组织制定或修订国家建筑法规和声学分类方案。 在本文件中，“住宅”一词指独立式和附属式住宅、带有多套公寓的建筑物以及独立住宅，住宅是家庭的居住空间。

This document describes criteria and procedures for acoustic classification of dwellings. The purpose of this document is to make it easier for developers to specify a classified level of acoustic quality for a dwelling, and help users and builders to be informed about the acoustic conditions and define increased acoustic quality. The document can also be applied as a general tool to characterize the quality of the existing housing stock and includes provisions for classifying the acoustic quality before and after renovation has taken place. By the acoustic quality for a dwelling is understood the quality of the acoustic performances typically included in building regulations, e.g. sound insulation towards neighbouring premises and road traffic as well as sound from service equipment. Sound insulation and room acoustics internally in a dwelling are not included in the acoustic classes defined. This document does not have a legal status in a country, unless decided by its own authorities. However, an additional purpose of this document is to help national authorities and standardization organisations to develop or revise national building regulations and acoustic classification schemes. For the purpose of this document, the term ”dwellings” refers to detached and attached dwelling-houses, buildings with several flats as well as individual dwellings, and a dwelling is the living space for a household.
