Abstract Exposure to noise is proven to have important repercussions on human comfort and health conditions. In recent decades, efforts to increase awareness among users have focused on highlighting the benefits of an appropriate acoustic indoor environment. In addition, given the significant increase in complaints about noise, the control, reduction, and limitation of sound transmission have become important issues to be considered in acoustic retrofit work in buildings. Much of the housing stock was built in a period characterized by the limitation or absence of standards, and renovation interventions should be geared towards existing buildings. However, despite the major potential to improve quality of life, only a handful of countries consider old buildings in their national Building Codes and regulations. The main aim of this work is to develop a comparative study of the acoustic requirements for indoor sound insulation between dwellings of existing buildings established in current building regulations around the world. The analysis of the documents concludes that the usual difference between requirements for new and existing buildings is 5 dB, both for airborne sound insulation and impact sound insulation. To this end, this paper provides the basis for discussion regarding future cooperation for the optimization of acoustic regulations for old buildings.

现有住宅建筑的声学改造：欧洲和世界其他国家住宅之间隔音的要求和建议

摘要 噪声暴露对人类的舒适度和健康状况有重要影响。近几十年来，提高用户意识的努力集中在强调适当的室内声学环境的好处。此外，由于对噪声的投诉显着增加，控制、减少和限制声音传播已成为建筑物声学改造工作中需要考虑的重要问题。许多住房存量建于一个以标准有限或缺乏为特征的时期，翻新干预措施应面向现有建筑。然而，尽管具有提高生活质量的巨大潜力，但只有少数国家在其国家建筑规范和法规中考虑了旧建筑。这项工作的主要目的是对世界各地现行建筑法规中规定的现有建筑住宅之间室内隔音的声学要求进行比较研究。对文件的分析得出结论，新建筑和现有建筑的要求之间的差异通常为 5 dB，包括空气声隔声和撞击声隔声。为此，本文为今后在旧建筑声学法规优化方面的合作探讨提供了基础。对文件的分析得出结论，新建筑和现有建筑的要求之间的差异通常为 5 dB，包括空气声隔声和撞击声隔声。为此，本文为今后在旧建筑声学法规优化方面的合作探讨提供了基础。对文件的分析得出结论，新建筑和现有建筑的要求之间的差异通常为 5 dB，包括空气声隔声和撞击声隔声。为此，本文为今后在旧建筑声学法规优化方面的合作探讨提供了基础。
