We can undertake Building Acoustic Design before you ever start on site which will provide junction details and wall build-ups that will comply with Building Regulations, providing the building is constructed as advised. This is often the most cost-effective way of getting through the Regs as the financial consequences of a test failure at completion can be considerable in terms of remedial work and re-testing.

Some of the equipment we use to take measurements are very sensitive to noise and the presence of even small noises can affect the test results. It is best that work is halted for the duration of the testing (approximately 2 hours for a typical set of tests), or for work to be only carried out on parts of the site where work will not affect the test area.

Rooms should be available in pairs, either vertically (separated by the party floor) or horizontally (separated by the party wall). They should be complete but unfurnished. In summary:

• All door and window seals, all sealants and all ventilation units.

• Carpets are not fitted in the test areas - where the impact of sound insulation testing is required, the floor surface needs to be bare without any finishes in place unless integrated as part of the construction of the floor.

• The rooms requiring testing should be free of curtains and furniture.

• Background noise - all high level noise, such as ground works, drilling and hammering etc should be stopped during the test period to reduce the background noise. We will endeavour to keep this downtime to a minimum.

• Access to all rooms requiring testing is clear

• A 240v mains power supply must be available; generators cannot be used due to noise.
