Computational Noise Modelling

Computational noise modelling is a tool that can be used to predict noise impacts, determine acoustic construction requirements and assess sound quality (such as reverberation or echo) and speech intelligibility. Often, we complete computational modelling in conjunction with monitoring of existing or representative existing noise sources, to allow analysis of a range of scenarios, operating conditions and meteorological influences.

Sophisticated computer modelling tools allow for the accurate prediction and design of acoustic control measures. We operate a range of acoustic software packages including Cadna/A and ENM for environmental and source noise prediction, INM (aircraft noise modelling) and Odeon for internal noise modelling of sound quality, speech intelligibility and noise breakout.

The CadnaA software in particular provides ANE with a powerful analytical tool for a range of planning, development and infrastructure projects. The software implements more than 30 international standards and guidelines for noise assessment. CadnaA uses powerful calculation algorithms, has extensive tools for object handling, offers outstanding 3D visualisation and the ability to import a range of standard drawing and image formats to provide enhanced presentation of noise modelling results and noise contours.

Our experience in noise modelling encompasses all commercial and industry sectors, as well as numerous residential, medical and sporting proposals. Examples of our broad experience in noise modelling includes:

Industrial projects:

  • Manufacturing plant;
  • Boiler plant;
  • Food processing operations;
  • Waste water treatment plant;
  • Power stations;
  • Mines;
  • Waste transfer stations and landfill sites;
  • Quarries;
  • Concrete batching plant;
  • Major pipeline proposals in Northern Territory and Queensland.

Commercial:

  • Shopping centres;
  • Residential apartments, and sub-divisions;
  • Office blocks;
  • Childcare centres;
  • Retirement villages;
  • Sports clubs;
  • Sporting venues and activities including skateparks, racing tracks, arenas;
  • Medical facilities.

Transportation noise modelling:

  • Major highways and roads in Queensland and New South Wales,
  • Railway noise impacts;
  • Noise from marine operations and ports;
  • Bridges and tunnel developments.
  • Military and civilian helicopter noise;
  • Aircraft ANEF and ANEC modelling for military and civilian operations;
  • Assessment of commercial and pilot (circuit) training noise impacts.
