  The Environmental Noise Directive 2002/49/EC which appeared in 2002 raised the question among those who are “experts in noise” how noise mapping and noise action planning should be implemented throughout Europe. They all agreed that, in view of the completely different calculation methods in the European countries, the calculation results reached and exposure figures collected would accordingly also be different and far from being comparable with each other. The only guarantee for comparable results...

• London Hotspots for Noise Nuisance Complaints [Infographic]

  Mar. 22, 2017

  As we continues our quest to build up a noise nuisance map of the UK, we recently turned our attention to our fair Capital, London. With 33 boroughs in Greater London, it was always going to be something of a time-consuming task to get the noise complaints data via Freedom of Information (FOI) requests. However, we were pleasantly surprised by the London Local Authorities efficiencies. The vast majority of data came back in under the 3 week FOI deadline. Click here to see the Infographic. As the statistics...

  Against this backdrop of economic change, a two-year study got underway across three Chilean cities led by the Univ. Austral. and was supported by the Chilean Ministry of the Environment. Academically titled: “Development and analysis of noise maps of three urban agglomerations using modeling software”, the study concentrated on the Chilean cities of Coquimbo – La Serena, Valdivia, and Temuco – Padre las Casas. It also included recordings and analysis of soundscapes in Valdivia. The final...

• Creating an entire country`s noise map - Case Study

  Aug. 27, 2015

  To comply with the European Union’s Environmental Noise Directive 2002/49/EC, member states are required to create updated noise maps for large urban areas and major transportation sources every five years. The English government commissioned a single project to calculate sound levels across the whole of England which resulted in the world`s biggest noise map. Challenge: To calculate noise maps for 26,000 km of roads, 5,000 km of railways and 65 urban areas within a very restricted timescale and budget. So...

• Implementing noise prediction standards in software

  May 14, 2015

  Software requirements in the 80`s Until the 80`s most consultancy projects were based on noise measurements due to complaints. As noise legislation became more strict, noise prediction became more important. New national and international noise prediction standards As there was no commercial software available many consultants started to develop their own prediction software First software No Graphical User Interface. Manual data entry, ASCII files in/out, small models Software requirements...
