Acoustic noise control in buildings for residential use in England and Wales is regulated using Approved Document E. This Building Regulation now applies to any kind of building used as a dwelling, including houses and apartments; and rooms for residential purposes, such as students and nurses accommodation, nursing homes and hotels. It also applies to dwellings that have been created as a result of a conversion or material change of use.
The aim of the regulation is to protect residents from the noise of activities in other rooms or adjoining properties. This has been highlighted as a major cause of tension between residents. The acoustic requirements are shown below in tables 1.1a & 1.1b:-
