To comply with the criteria set out in Part E of the Buildings Regulations you will need to ensure your dwelling completes a sound insulation test. This is to ensure that your build demonstrates acceptable levels of airborne and impact noise levels. These regulations apply to both new build and refurbishments or conversions on all types of dwellings.
Airborne sound refers to noise that is directly transferred via ‘air’ and includes things such as televisions etc. Impact sound refers to any noise that is transmitted through impact itself via connecting floors or walls. There are two main types of procedure to test such noise levels. An airborne sound test uses a noise machine which emits a level of white noise from one room to the next. Impact sound levels are tested by using a tapping machine which can simulate such things as footsteps. The results from both of these tests are accumulated and recorded in compliance with the information as set out in the building regulations.
It is important to be aware of the acoustic design as implementing the wrong type of design or materials into your build can have a negative impact on your sound insulation test results. Maintaining the usage of high end construction materials will set you in good stead to pass this test. The test itself will take place at Pre-completion stage which means that all doors are in place, windows and trickle vents should be fitted and there should also be power on site. It is beneficial, as with all compliance testing, to gain professional advice at an early stage to ensure that you receive that pass.
