If you’ve googled “what is sound insulation testing”? we can help. Also known as acoustic insulation testing, sound insulation tests measure how much noise travels through a property’s walls, floors and ceilings to neighbours or adjoining buildings.
Why do I need it?
Now we’ve covered ‘what is a sound insulation test?’, here’s why you need one.
UK building regulations require sound insulation testing. This is to ensure a good quality of life for those living within and around the property.
You will almost certainly need sound insulation testing if a new build or conversion results in two adjoining dwellings being separated by party elements. However, you may not need a test if you construct these elements with ‘robust details’. Robust details are materials that are proven to provide effective acoustic insulation
How is it done?
To test the airborne acoustic insulation of a party element, our technicians will place speakers generating 100 decibels of white noise in a space. Next, we’ll compare the average sound pressure level in the room using a moving microphone. Then, our technicians measure the average sound pressure level in the adjoining room and compare the two sound pressure levels.
Our technicians use a tapping machine to hit the party element – usually the floor – to create impact sound. They will then take measurements in the adjoining room, in third octave bands from 100 Hz to 3150 Hz. We’ll take measurements in at least four different positions, at least six times.
The results of these tests must meet or exceed values set by Part E of The Building Regulations.
When should it be carried out?
However, we would also advise that you hire UKBC from the outset. We can provide specific recommendations throughout the project, to ensure your building passes and prevent the need for costly remedial action.
