Good Hearing?
A typical person with good hearing can hear from about 20Hz to 20kHz (the audio bandwidth). A person's voice will usually range from 500Hz to 2kHz...more

Air Testing is sometimes referred to as Domestic Air pressure tests, Domestic Air tightness tests, Domestic Air tests, Domestic Air pressure testing, Domestic Air tightness testing, Domestic Air leakage testing.
Air Leaking Testing Across the UK
What Does An Air Leakage Test Involve?
An air test involves placing a large fan, or several fans, to an opening within the property; usually a doorway. The fans will increase and decrease in speed that will in-turn change the building's air pressure and record the results. Please note: an air test cannot be carried out if wind speed is more than 13mph. 3 metres per second is the ideal wind speed when undertaking an air test in the UK.
There should be no outside access once the test has begun for approximately 90 minutes so plan accordingly. Workers can still do their job inside the property, within reason, though may feel some discomfort due to the noise of the fan and the draught that will be felt throughout the building.
During an air test in the UK the pressure of the room will be tested and as such all windows and doors that lead outside must be securely closed to avoid them swinging open and the test being abandoned. Similarly, all internal doors should be wedged open to avoid being slammed shut. Furniture will not be affected during the test, but smaller items such as paper must be held down or removed completely so they're not blown about.
What Air Permeability Rating Do I Need?
Your air permeability rating resembles the amount of uncontrolled air that's leaking from the dwelling. A passing score in the UK is 10 m³/(h.m²). If the air test fails, we will help you identify where these leakage areas occur in the hope that a passing rate will be achieved following a re-test.
How Many Properties Need An Air Tightness Test?
The number of tests required are as follows:
- 4 or less properties of the same type: one test needed per type
- More than 4 but less than 40 dwellings of a type: at least two tests of each type
- More than 40 properties of a type: 5% of each type UNLESS the first 5 get a passing score - then this can be dropped to just 2%
When Should The Test Take Place?
A building envelope will need to be completed before the air test takes place - which should be one of the last surveys undertaken once all the walls, windows, doors etc. are complete and sealed. This ensures no air will escape and prevent drafts through the property which will in-turn improve your air permeability score.
Do I Need An Air Leakage Test?
Planning your test in advance will help our experience air assessment team covering the UK to determine how many tests you'll need ahead of time per property and will be happy to offer advice on the best ways to gain your air permeability rating.
Part L of the Government building regulations explains that on a large plot of new houses that are built to a similar specification, only a sample of the houses will need to be air tested.
Domestic properties and commercial buildings over a certain size must have a passing air leakage certificate before the property can be handed over following a sale. All new buildings in England and Wales have had this requirement since 2006 and in Scotland this has been mandatory since 2010.
