a. Existing background noise levels at the nearest or most exposed noise-sensitive development to the proposed development; or at a location where background conditions can be argued to be similar. b. The rating noise level resulting from the proposed noise-source. This can be based upon reference to similar installations or sites, or determined by calculation. The noise impact assessment must be carried out by a suitably qualified acoustic consultant holding a recognised acoustic qualification. An ISO 1996 compliant noise impact assessment has been carried out for the development (Pol8.v01).Background traffic noise levels from traffic is assessed to 55-65 dB. Norwegian Regulations on technical requirements for building works (TEK 10) sets a limit of 45 dB for technical installations on the roof or façade (Pol 8.v01). Noise generated from the building will therefore be below the background noise from traffic.The noise impact assessment has been carried out by a suitably qualified acoustician (Pol8.v02).
