Attachment 7 - Acoustic Report

9.2     Road Traffic Noise
All building treatments for road traffic noise shall be determined at the Building Approval stage in
accordance with the assessment requirements of the Queensland Development Code Part 4.4. For
reference, preliminary noise categories are nominated in Table 14.


9.2.1    Glazing
The minimum glazing treatments presented in Table 14 are required to comply with the following:

       The minimum glass thickness specified shall not be reduced regardless of the R w performance
        of the glazing system.
       If compliance cannot be achieved with the minimum R w ratings, the glazing system shall be
        upgraded until compliance is achieved.
       Glazing specified with acoustic seals requires a Q-lon seal or an equivalent product, mohair
        seals are not acceptable.
       The glazier shall provide NATA test reports on request to verify compliance with the minimum
        Rw ratings. Generic reports are not acceptable.
