Acoustic Testing
Building acoustic testing is a testing procedure used to determine the sound insulation performance of separating walls and floors between adjoining properties. The tests are carried out by applying a controlled sound pressure on one side of the separating structure and measuring the sound pressure level difference. This measurement combined with the absorption level in the room (reverberation time) are used to represent the acoustic performance of the structure.
At Forsah we offer building acoustic testing in compliance with Part E of the technical guidance documents. Our engineers are highly trained in building acoustic measurement, and are sound insulation testing register Ireland (SITRI) accredited. This combined with our state-of-the-art equipment and dedication to customer service makes us the number 1 choice in residential projects for all sound insulation test certificates.
Types of Acoustic Tests
There are a range of acoustic tests carried out in building acoustic testing, all of which are carried out by Forsah. These ‘set of tests’ are shown below:
Airborne sound tests on separating walls
Airborne sound tests on separating floors
Impact sound tests to floors
Reverberation sound tests
Requirements for Acoustic Testing
Irish Building regulations require that acoustic tests are carried out in instances where there are separating walls and floors in adjoining dwellings. All tests need to be carried out to the methods set out in ISO-16283 –1:2014 and ISO16283-2:2014. The performance requirements which need to be achieved are detailed in TGD part E Table 1 as shown below.

On development sites, tests need to be carried out on a proportion of the dwellings. The quantity of tests required and number of tests to be completed per dwelling are detailed below. Tests need to be carried out before the dwelling is furnished and in the case of floor impact testing floors there cannot be any floor covering installed. On each site, at least one ‘set of tests 'should be carried out on a dwelling group in the first four dwellings
