To demonstrate compliance with the Building Regulations Technical Documents Part E on Sound 2014, construction projects in Ireland now require compulsory sound insulation testing. Technical guidance document Part E (2014) of the Building Regulations 1997 (S.I. no. 497 of 1997) relates to the mitigation of sound transfer between dwellings and rooms within a building. The regulations state that walls and floors must have “reasonable resistance” to airborne and impact sound. No consideration is given to the nature or location of the building or potential noise sources.
Irish Sound Insulation Testing – New Building Regulations (TGD-E)Developments will require the testing of separating walls and floors to achieve compliance with Part E of the building regulations. Sound Insulation tests include airborne and impact noise transfer through new or existing buildings. Tests are carried out using relevant standards and are assessed against guidance values in the Irish Building Regulations Technical Guidance Document E (Sound), 2014.
Do you require Sound Insulation Testing? All new dwellings and extensions to homes which adjoin other buildings will require sound insulation tests. Any construction works involving a material change of use that results in a building (or part thereof) becoming used as one or more dwellings.
How does Sound Insulation Testing work? The Sound Insulation tests include both Airborne and Impact tests. The number of tests required depends on the layout of your build and how many separating walls and floors you have. Testing should occur as early as possible to identify any acoustic weaknesses early in the construction process. Carpets and temporary floor coverings should not be fitted until a pass has been achieved. To watch a video on sound insulation testing, please click on the image below.
How many tests do I need? To comply with the requirements of Technical Guidance Document E (2014) of the Building Regulations, the minimum test programme is a function of the number of residential units to be constructed and variation in the construction types. A full set of tests for an apartment consists of 2-floor tests(2 x airborne and 2 x impact) and two wall tests (airborne). Impact tests are not carried out on semi-detached properties or terrace arrangements where residential developments are side by side. ICAN Acoustics are full members of the Association of Acoustic Consultants of Ireland (AACI). We provide sound insulation testing services for construction companies and the necessary acoustic consultancy services associated with this specialist area. ICAN Acoustics welcomes the formation of other groups, such as Sound Insulation Test Register Ireland (SITRI) and the benefits of providing basic sound insulation tester training (at a technician level). It is, however, essential to recognise that formal academic training in acoustics is a crucial requirement for the industry and helps ensure that those in Sound Insulation Testing are qualified to provide any design consultancy advice.
Who is qualified to carry out Sound Insulation Testing? Diarmuid Keaney of ICAN Acoustics has completed the “Advanced Sound Insulation Testing / Training Course” for ISO Parts 1 & 2 as per Building Regulations Technical Guidance Documents Section E – 2014. This training was held at Sound Research Laboratories in the UK on February 10th. 2016. It is worth noting that as part of Diarmuid Keaney’s Diploma in Acoustics and Noise Control (2004), he completed a specialist module in Architectural Acoustics, including Sound Insulation Testing theory and its application. The Institute of Acoustics runs the Diploma in Acoustics and Noise Control, and upon successful completion of the course examinations, Diarmuid was awarded merit for his final grade.

What are the key points I need to know about TGD-E? Regulation E1 aims to ensure that dwellings achieve reasonable levels of sound insulation from sound transmission emanating from attached buildings or differently occupied parts of the same building. Regulation E2 aims to protect dwelling occupants from the noise of reverberation in common internal areas that provide direct access to a dwelling or dwellings. These Regulations also amend Article 13 of the Building Regulations 1997 to require Part E to apply to an existing building or part of a building which undergoes a material change of use to a dwelling. The amendments to Part E of the Building Regulations and the associated technical guidance meet the overall objective of securing reasonable health and safety standards for persons in or about buildings regarding the passage of sound. The operative date of the Regulations is 1 July 2015.
What is the law on sound insulation testing? Technical guidance document Part E (2014) of the Building Regulations 1997 (S.I.no. 497 of 1997) relates to the mitigation of sound transfer between dwellings and rooms within a building. The regulations simply state that walls and floors must have “reasonable resistance” to airborne and impact sound. No consideration is given to the nature or location of the building or potential noise sources. Our test services come under the ‘Ancillary Certification, Part E – Sound Building Control (Amended) Regulations 2014.’
What are ‘Ancillary Certificates’ and who is an ‘Ancillary Certifier’? “Ancillary Certificates” means a certificate other than a statutory certificate of compliance as prescribed in the Building Control Regulations given by a competent person to confirm compliance of elements of the building, design or works with Building Regulations; “Ancillary Certifier” means a person proposed to issue such a statement. (Note: a “person” also includes a company); “Assigned Certifier” means the competent, registered professional person so assigned, in accordance with the Building Control Regulations.

What standards do ICAN Acoustics use when carrying out a sound insulation test?
On-site testing is carried out using:
- EN ISO 16283-1 :2014 Field measurement of sound insulation in buildings and of building elements — Part 1: Airborne sound insulation.
- EN ISO 16283-2 :2015 Field Measurement of Impact Sound Insulation of Floors — Part 2: Impact sound insulation.
