We can assist in assessing the actual noise category and hence save you thousands of dollars on your building requirements by potentially dropping the noise category requirement.<\/span> <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n Software such as SoundPlan, (road or rail noise models), PEN 3D, CORTN calculations can be used to model future traffic noise levels.

\n Additionally we can help you with alternative \u201clight weight\u201d wall systems which may not be listed in the QDC MP4.4 policy. An alternative acoustic solution, as a building element, may be designed and certified by our team.<\/span><\/p>\n![\"transportation1\"](\"http:\/\/www.alphaacoustics.com.au\/wp-content\/uploads\/2014\/12\/transportation1.jpg\")
