Before a sound insulation test can be carried out, there are a number of requirements (our checklist):
- Pre-agreement of access to both properties (if the dwellings are occupied). This is not a requirement in new builds as part of the pre-completion tests where the dwellings are not yet occupied.
- Mains power should be available in both dwellings (220V, 50Hz AC, supplied via a 13amp UK socket).
- All doors, windows and wall vents should be fitted. Please note that these are pre-completion tests, where the building should be close to completion.
- Access to source and receiver rooms is essential throughout the tests.
- Non-permanent floor coverings should not be fitted, however permanent floor coverings (which are bonded with non-removal warning labels) should be in place to allow floor tapping tests to be carried out.
- There should be no construction noise at the time of measurement i.e. noise from tradesmen or external machines. Measurements outside construction hours can be provided on request.
- Where early fire detection sounders are used, batteries should be installed so that the units do not ‘chirp’ during sound insulation tests.
- Adequate site lighting should be in place if testing is to be carried out in the evening and night, outside normal construction hours.
