British Standard BS 5821:1980: Ratings of the sound insulation of floating party floors
Earlier papers listed floors tested to obtain field data on common types and gave performance ratings for airborne and impact insulation in terms of 'aggregate adverse deviations' (AADs) relative to Grade I reference values. Ratings in terms of the system defined in BS 5821:1980 are given here on the basis of the same data. IP10/83 

British Standard BS 5821:1980: Ratings of the sound insulation of post-1970 party walls
Performance ratings according to the system defined in BS 5821:1980 are given for the types of party wall for which (in earlier papers) ratings in terms of 'aggregate adverse deviations' relative to the Party Wall Grade reference values were given. IP9/83 

Dealing with poor sound insulation between new dwellings
When a test demonstrates that the sound insulation between new houses, flats or rooms for residential purposes does not meet the performance requirements of Section 0 of Approved Document E, appropriate remedial treatment is needed. This Information Paper describes how to rectify faults that can cause sound insulation to be lower than expected. Its advice is intended for developers, builders, designers, and others concerned with rectifying defects that cause poor sound insulation. IP14/02 

Effects of environmental noise on people at home
This paper will be of interest to all those involved in the assessment of environmental noise and the design and assessment of housing. IP22/93 

Improving sound insulation
BRE inspections of rehabilitation work in progress have revealed instances of inadequate separating walls between dwellings, gaps or absence of walls in roof spaces, and holes alongside floor joists or other timbers built into the walls. The principle of sound insulation is to ensure that the resistance of separating walls is satisfactory by blocking all holes or by constructing an independent leaf. This Guide advises builders, householders and landlords on diagnosing a sound insulation problem and deciding on remedial action. There is also advice on sound insulation for flat conversions.  GR22 

Improving the sound insulation of separating walls and floors
The Digest suggests methods of improving the sound insulation between adjoining dwellings. It indicates the improvement in insulation likely to be achieved by such methods as adding an independent leaf to one side of the wall, or constructing an independent ceiling or floating floor. DG293 

Insulation against external noise
This Digest explains how windows, walls and roofing affect the level of noise that is transmitted into a building from the outside. Various factors are involved, and certain planning measures will reduce exposure to outside noise. DG338 

Methods for improving the sound insulation between converted flats
Noise from neighbours is a common complaint from occupants of houses converted into flats. Even if party floors have been sound-insulated, flanking transmission through walls may allow the problem to continue. This IP describes solutions and advice based on field trials of various options. IP6/88 

Minimising noise from domestic fan systems
Fan systems can be noisy. This guide describes how to design a fan system for removing from dwellings condensation and odours with the minimum of noise disturbance. Applies to domestic fan systems and to fan-assisted radon sump systems. GG26 

Quiet homes
This manual is a guide to achieving good sound insulation between dwellings. It complements the Guidance given in England and Wales Building Regulation Approved Document E. The information is not about innovative construction types with enhanced sound insulation but about avoiding mistakes that reduce the sound insulation of existing widely used construction types. BR358 

Rain noise from glazed and lightweight roofing
This paper is intended to help designers to assess the likely effect of rain noise from lightweight roofs and roof elements on the indoor ambient noise levels in rooms. It contains results from measurements of the sound intensity levels caused by artificial heavy rainfall on roof glazing, polycarbonate roofing and ETFE roofing, the latter with and without rain suppressors. The measured sound intensity data allow comparison of products and estimation of the reverberant sound pressure level in a room due to rain noise. IP2/06 

Reducing impact and structure-borne sound in buildings
Noise from neighbours is one of the principal causes of complaint about the indoor environment in dwellings. The noise is generated by airborne sound sources such as speech, or by impact sound sources such as footsteps on floors and stairs, banging doors and plumbing. This paper describes methods for reducing impact and structure-borne sound in buildings using both remedial treatments and design features. The advice will be mainly of use to architects, builders, and others concerned with designing new buildings or upgrading existing ones. IP4/01 

Sound control for homes
Provides practical, state-of-the-art advice on the control within dwellings of noise from outside sources and noise transmitted within and between dwellings. BR238 

Sound insulation and the 1992 edition of Approved Document E
In the 1992 revision to Approved Document E, the technical specifications in England and Wales, Scotland and Northern Ireland have been harmonised. There are two new sections, one describing an additional approval procedure based on full-sized mock-up tests, the other dealing with material change of the use of a dwelling. IP18/92 

Sound insulation: basic principles
The constructional techniques available for providing a reasonable standard of sound insulation between dwellings are based on a few simple principles. This publication explains the terminology and basic principles of the subject. It complements Digests, 333, 334, 338 and 347. DG337 

Specifying dwellings with enhanced sound insulation
This document is a guide to specifying construction details that have been shown to provide enhanced levels of sound insulation. Since 1966, there has been an increase in noise producing devices available to domestic users. This guide attempts to bring together the information on masonry construction and framed construction, including new research on timber floors. But good levels of sound insulation also depend on workmanship on-site. Advice on achieving this can be found in the companion document, BR358 Quiet homes, a guide to good practice and reducing the risk of poor sound insulation between dwellings. BR406 

The insulation of dwellings against external noise
This paper describes the relationship between the levels of noise from road traffic and different types of window. Various methods used to quantify noise reduction are considered, together with methods for maintaining ventilation while achieving reduced noise levels. IP12/89 

The noise climate around our homes
Reports on a noise incidence study undertaken to establish the noise climate outside homes in England and Wales. IP21/93 

The sound insulation provided by windows
Describes experiments on a number of elements which affect sound insulation, including the sealing of openable panes, the type of frame material, the size of the window panes, and the spacing of panes in multiple pane systems. IP6/94

Earlier papers listed floors tested to obtain field data on common types and gave performance ratings for airborne and impact insulation in terms of 'aggregate adverse deviations' (AADs) relative to Grade I reference values. Ratings in terms of the system defined in BS 5821:1980 are given here on the basis of the same data. IP10/83 

British Standard BS 5821:1980: Ratings of the sound insulation of post-1970 party walls
Performance ratings according to the system defined in BS 5821:1980 are given for the types of party wall for which (in earlier papers) ratings in terms of 'aggregate adverse deviations' relative to the Party Wall Grade reference values were given. IP9/83 

Dealing with poor sound insulation between new dwellings
When a test demonstrates that the sound insulation between new houses, flats or rooms for residential purposes does not meet the performance requirements of Section 0 of Approved Document E, appropriate remedial treatment is needed. This Information Paper describes how to rectify faults that can cause sound insulation to be lower than expected. Its advice is intended for developers, builders, designers, and others concerned with rectifying defects that cause poor sound insulation. IP14/02 

Effects of environmental noise on people at home
This paper will be of interest to all those involved in the assessment of environmental noise and the design and assessment of housing. IP22/93 

Improving sound insulation
BRE inspections of rehabilitation work in progress have revealed instances of inadequate separating walls between dwellings, gaps or absence of walls in roof spaces, and holes alongside floor joists or other timbers built into the walls. The principle of sound insulation is to ensure that the resistance of separating walls is satisfactory by blocking all holes or by constructing an independent leaf. This Guide advises builders, householders and landlords on diagnosing a sound insulation problem and deciding on remedial action. There is also advice on sound insulation for flat conversions.  GR22 

Improving the sound insulation of separating walls and floors
The Digest suggests methods of improving the sound insulation between adjoining dwellings. It indicates the improvement in insulation likely to be achieved by such methods as adding an independent leaf to one side of the wall, or constructing an independent ceiling or floating floor. DG293 

Insulation against external noise
This Digest explains how windows, walls and roofing affect the level of noise that is transmitted into a building from the outside. Various factors are involved, and certain planning measures will reduce exposure to outside noise. DG338 

Methods for improving the sound insulation between converted flats
Noise from neighbours is a common complaint from occupants of houses converted into flats. Even if party floors have been sound-insulated, flanking transmission through walls may allow the problem to continue. This IP describes solutions and advice based on field trials of various options. IP6/88 

Minimising noise from domestic fan systems
Fan systems can be noisy. This guide describes how to design a fan system for removing from dwellings condensation and odours with the minimum of noise disturbance. Applies to domestic fan systems and to fan-assisted radon sump systems. GG26 

Quiet homes
This manual is a guide to achieving good sound insulation between dwellings. It complements the Guidance given in England and Wales Building Regulation Approved Document E. The information is not about innovative construction types with enhanced sound insulation but about avoiding mistakes that reduce the sound insulation of existing widely used construction types. BR358 

Rain noise from glazed and lightweight roofing
This paper is intended to help designers to assess the likely effect of rain noise from lightweight roofs and roof elements on the indoor ambient noise levels in rooms. It contains results from measurements of the sound intensity levels caused by artificial heavy rainfall on roof glazing, polycarbonate roofing and ETFE roofing, the latter with and without rain suppressors. The measured sound intensity data allow comparison of products and estimation of the reverberant sound pressure level in a room due to rain noise. IP2/06 

Reducing impact and structure-borne sound in buildings
Noise from neighbours is one of the principal causes of complaint about the indoor environment in dwellings. The noise is generated by airborne sound sources such as speech, or by impact sound sources such as footsteps on floors and stairs, banging doors and plumbing. This paper describes methods for reducing impact and structure-borne sound in buildings using both remedial treatments and design features. The advice will be mainly of use to architects, builders, and others concerned with designing new buildings or upgrading existing ones. IP4/01 

Sound control for homes
Provides practical, state-of-the-art advice on the control within dwellings of noise from outside sources and noise transmitted within and between dwellings. BR238 

Sound insulation and the 1992 edition of Approved Document E
In the 1992 revision to Approved Document E, the technical specifications in England and Wales, Scotland and Northern Ireland have been harmonised. There are two new sections, one describing an additional approval procedure based on full-sized mock-up tests, the other dealing with material change of the use of a dwelling. IP18/92 

Sound insulation: basic principles
The constructional techniques available for providing a reasonable standard of sound insulation between dwellings are based on a few simple principles. This publication explains the terminology and basic principles of the subject. It complements Digests, 333, 334, 338 and 347. DG337 

Specifying dwellings with enhanced sound insulation
This document is a guide to specifying construction details that have been shown to provide enhanced levels of sound insulation. Since 1966, there has been an increase in noise producing devices available to domestic users. This guide attempts to bring together the information on masonry construction and framed construction, including new research on timber floors. But good levels of sound insulation also depend on workmanship on-site. Advice on achieving this can be found in the companion document, BR358 Quiet homes, a guide to good practice and reducing the risk of poor sound insulation between dwellings. BR406 

The insulation of dwellings against external noise
This paper describes the relationship between the levels of noise from road traffic and different types of window. Various methods used to quantify noise reduction are considered, together with methods for maintaining ventilation while achieving reduced noise levels. IP12/89 

The noise climate around our homes
Reports on a noise incidence study undertaken to establish the noise climate outside homes in England and Wales. IP21/93 

The sound insulation provided by windows
Describes experiments on a number of elements which affect sound insulation, including the sealing of openable panes, the type of frame material, the size of the window panes, and the spacing of panes in multiple pane systems. IP6/94
