Modeling and Analysis of Noise
MetadataShow full item record
Noise is an environmental issue which may have a negative impact on health and wellbeing. Norwegian legislation states recommended noise limits for inhabited and other noise sensitive areas. Areas susceptible to noise problems should have mapped noise zones, to visualize and clarify any noise abatement needs.The mining industry in Norway generates a substantial amount of noise. As a result, they are required to map the noise level of the surrounding area. Today many companies hire external consultants to create noise maps for their areas. This is very expensive and may take a substantial amount of time and some companies would prefer to be able to do the mapping themselves. There are software solutions available for this purpose, however these are expensive and comprehensive solutions. Some of these solutions would require a change of software system. As MicroStation is used by many today, a plug-in that handles noise analysis and modeling in MicroStation has been requested.The plug-in created in this project may be used in the mining industry and in other projects, such as road or industry projects. It shows noise mapped as color coded contour lines in accordance with Norwegian legislation. In addition, it shows noise maps with contour lines for every 3 dB and exact values for selected points and house facades.
