Principles of Building Acoustics

Building acoustics is the science of controlling noise within buildings. This includes minimising noise transmission between compartments and the control of sound characteristics within a space. The term ‘building acoustics’ embraces both sound insulation and sound absorption. 

Sound Absorption

Sound absorption refers to the process by which a material, structure, or object takes in sound energy when sound waves are encountered, as opposed to reflecting the energy. Part of the absorbed energy is transformed into heat and part is transmitted through the absorbing body.

Sound Insulation

Sound insulation is used to describe the reduction of sound that passes between two spaces separated by a dividing element. The sound energy that passes between these two spaces may travel through the dividing element (direct transmission) or through the surrounding structure (indirect or flanking transmission). It is important to distinguish between both methods of sound transmission as the walls and floors which flank the dividing element, can sometimes contribute significantly to the level of sound transmission. The presence of nearby windows, doors, service ducts, etc. can also affect the level of sound transmission performance.

Legislation & Guidance

Tech Doc E

Republic of Ireland Building Regulations – Sound Technical Guidance Document E, published by the Department of the Environment, Heritage and Local Government, is part of a series of documents forming the building regulations relating to sound.This  document specifies the required on-site performance criteria for both airborne and impact sound transmission values for separating elements between individual residential dwelling units. The current building regulations do not set out any specific criteria for buildings other than residential dwelling units. It is therefore often the designer’s choice to specify the appropriate level of sound performance of the internal dividing elements of an individual domestic dwelling and for other building types. However, guidance to the level of sound performance is often based on specific sector guidance and previous experience. 

Northern Ireland – Acoustic Standards BS 8233 is a code of practice which provides guidance to acoustic ratings appropriate to different building types.
