Building Regulations Part E - Passage of Sound
What is Sound Insulation Testing?
Building Regulations requires that dwellings are sound tested before completion (pre-completion testing) to demonstrate suitable sound insulation, in compliance with 'Approved Document E of the Building Regulations for England and Wales – Resistance to the Passage of Sound.'
Our trained and experienced engineers will guide you through this process and ensure you have the best possible chance of passing first time.
We operate throughout the UK and, providing we have all the information in place before testing, we can tell you how your test performed straight away.
Do I need Sound Insulation Testing?
Under Building Regulations Approved Document E, you will require sound insulation testing if you are:
Sound insulation tests are not required on:
What do I need to do to pass Part E testing?
In order to undertake any testing, we first require plans, sections and elevations of the building being tested and any other building details available to ensure we can plan the tests and maximise the chances of passing.
Procedure
The airborne sound insulation test is carried out with a loudspeaker for a steady source of noise on one side of the partition (wall or floor) to be measured. The corresponding sound level is measured on the other side of the partition.
Impact tests are carried out by using a tapping machine placed on the floor to be measured. The noise level is then recorded in the room below and calculations based on these measurements are undertaken and the results compared to the Building Regulations Part E requirements for the given type of the building.
Failures
Transmission via air paths through a partition or floor will be evident by the presence of higher frequency noise on the receiving side.
Flanking transmission occurs where airborne or impact sound passes under, over or around a wall or floor partition. The sound travels along shared building elements of adjacent structures. This can be detected with higher levels of low frequency noise on the receiving side.
