Sound Testing

Sound Testing Summary

Sound TestingJOT Energy Consultants carry out Acoustic/Sound Testing in compliance with TGD Part E 2014. From the 1st of June 2015 all residential developments must apply acoustic testing sampling in compliance with Technical Guidance Document Part E. JOT Energy Consultants provide Independent Acoustic Testing and Reporting in compliance with TGD Part E.

Developments will require the testing of separating walls and floors to achieve compliance with Part E of the building regulations. Sound Insulation Testing checks for both airborne and impact travel through new or existing buildings. This may affect party walls and floors between new and existing buildings, or between spaces within a new development entirely.

Under revised sound regulations which came into force in July 2015, sound testing is now mandatory on attached dwellings.

A large part of our business revolves around helping the construction related services sector and stakeholders with Part E Compliance, this involves sound testing and sound compliance certification

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.


The Department of the Environment, Community & Local Government (DECLG) published new Building Regulations pertaining to sound in December 2014. An updated and enhanced Technical Document E Sound followed in January 2015. The key aspects of the new guidance may be summarized as follows:

  • For the first time in Ireland, minimum standards of sound insulation performance have been use to define reasonable resistance to sound;
  • Reverberation in common internal parts of buildings has been introduced as an issue requiring consideration; and
  • Mandatory pre-completion testing is required in order to demonstrate compliance with the requirements of the Regulations.

TGD E places a strong emphasis on the competence of testers, as illustrated by the following extracts:

Competency of Tester

To ensure a proper standard of testing, it is essential that persons are competent in the measurement of sound insulation in buildings to the relevant ISO Standards i.e. ISO 16283 Part 1 and ISO 140 Part 7 series, possess sufficient training, experience and knowledge appropriate to the nature of the work he or she is required to perform having particular regard to the size and complexity of such works.”


Sound insulation tests carried out by a person certified by an independent third party to carry out this work offers a way of ensuring that such certification can be relied upon.
