To demonstrate compliance with the new the new 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 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.
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 dwellings which adjoin other buildings will require sound insulation tests
Any construction works, involving a material change of use that result in a building (or part thereof) becoming used as one or more dwellings.
How does Sound Insulation Testing work?
The Sound Insulation tests includes both Airborne and Impact tests. The number of tests required is dependent on the layout of your build and how many separating walls and floors you have.
Testing should take place as early as possible so that any acoustic weaknesses can be identified early in the construction process. Carpets and temporary floor coverings should not be fitted until a pass has been achieved.

How many test 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 2 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 Acoustic Consultants Sound Insulation Testers of Ireland (ACASITI). We provide specialist sound insulation testing services for construction companies as well as the necessary acoustic consultancy services associated with this specialist area.
ICAN Acoustic also welcomes the formation of other groups such as Sound Insulation Test Register Ireland (SITRI) and benefits associated with providing formal training to candidates new to the area of acoustics.
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 also that as part of Diarmuid Keaney’s Diploma in Acoustics and Noise Control (2004), he completed a specialist module in Architectural Acoustics which included Sound Insulation Testing theory and its application. The Diploma in Acoustics and Noise Control is run by the Institute of Acoustics and on successful completion of the course examinations, Diarmuid was awarded a merit as his final grade.
