What is involved
• The test is carried out between a pair of rooms separated by a party wall or floor.
• It involves setting up a noise source in the room on one side of the party wall or floor and measuring this noise on the other side of the partition.
• We will require simultaneous access to both sides of the wall or floor
• In the interest of health and safety, we cannot allow anyone in the room that we are testing to or from as the equipment emits a sound over 100 Db.

Required site conditions
• Quiet conditions will be required – with no work at all near the rooms in question.
• Staff should be informed of the Sound Testing programme and be prepared to leave punctually as required.
• External noisy activity within control of the site manager should be stopped.
• ATSPACE should also be informed of any other noisy activity likely to be occurring on the test day e.g.roadworks.
• The tests are likely to last several hours – depending on the number of tests involved.
