  • Estimating exposure to excessive noise in cities

    The 2002 Environmental Noise Directive seeks to provide a uniform basis for measuring and addressing noise pollution, one of the most important urban environmental issues for the EU. New research has assessed city-dwellers' exposure to noise and proposes traffic management strategies to reduce harmful levels. Clear evidence is growing for wide-ranging negative health effects of noise pollution, ...

  • Reviewing the multiple impacts of noise pollution

    While occupational exposure to noise has declined, ‘social’ exposure in the form of personal music players or rock concerts is estimated to have tripled for young people since the 1980s. A new review examines studies that have investigated noise sources, including environmental (e.g. traffic) and social (e.g. via headphones) sources. The review also explores research into the range of ...

  • Urban greening reduces noise pollution

    Green roofs have the potential to significantly reduce road traffic noise in the urban environment, according to a new study. The results suggest that greening of roofs and walls with materials suitable for growing plants softens the urban environment keeping sound levels low, whereas hard, manmade structures tend to amplify traffic noise. The Environmental Noise Directive (2002/49/EC)1 ...

  • Mapping noise pollution simply and cost-effectively

    To manage noise, it must first be assessed. Several commercial noise prediction tools exist, but they are often complex and expensive. A new Irish study evaluates a simpler tool and demonstrates that it produces very similar results to standard commercial software. The European Directive on Environmental Noise1 requires Member States to draw up strategic noise maps and action plans. A noise map ...

  • Exposure to Environmental Noise - World Health Organisation Report

    Exposure to environmental Noise If you are exposed to environmental noise such as motorised transport, you may experience feelings of stress and discomfort. Monitoring these noise levels is important to protect yourself and workers exposed to high levels of noise, whether it be industrial or environmental.   There are many different sources of environmental ...

  • Noise mapping book features Brüel & Kjær expert

    A new book entitled ‘Noise Mapping in the EU: Models and Procedures’ has been published, containing a chapter written by Brüel & Kjær’s Application Specialist Douglas Manvell. It shows how to integrate data with geographical information systems, improve accuracy in model and prediction software - and assess different methods and descriptors for evaluating ...

  • New method to accurately estimate levels of urban noise

    New research has identified 25 variables that influence noise in urban areas. By combining these into an equation, the study produced an accurate tool to describe urban sound environments that could be useful in urban planning. Environmental noise, especially in urban areas, has a significant impact on human well-being. Ensuring that noise does not reduce quality of life requires an accurate ...

  • Bruel & Kjaer’s Noise Mapping Software Heads East

    To meet growing demand from Consultants and other Environmental experts in China, Brüel & Kjær’s noise prediction software - Predictor-LimA - is now available in Chinese. Created by Softnoise and distributed by Brüel & Kjær, Predictor-LimA Software Suite provides environmental noise calculation, mapping and analysis. It’s powerful, intuitive and cost ...

  • Exa Releases PowerACOUSTICS 2.0 with Far- Field Analysis for Community and Environmental Noise

    Exa® Corporation, a global innovator of fluids simulation solutions for product engineering, today announced the release of PowerACOUSTICS® 2.0. Exa’s newest release offers a Far-Field Noise Module for accurate numerical prediction of flow-induced ...


  • Noise Barrier efficiency calculations now identify imperfect barriers

    Brüel & Kjær today announced its Predictor-LimA noise mapping and prediction software now automatically calculates noise barrier efficiency to identify inadequate barrier performance. In addition, by modelling how well a noise barrier performs along the transmission loss spectrum, acoustic experts can more easily identify the most effective noise barrier for a specific ...

  • Air traffic management to balance CO2 emissions and noise pollution

    Speed constraints for aircraft are put in place, at some airports, to minimise noise pollution in local areas, however, such practices can be very fuel-inefficient. New research has now shown that relaxing departure speed limits could substantially reduce CO2 emissions, while maintaining acceptable noise levels. The aviation industry is a major contributor to emissions of greenhouse ...

  • TNEI Provides Expert Witness Services at Public Inquiries in Relation to Noise

    Wind farm projects are often subject to high levels of scrutiny by planning authorities and third parties. Due to the high profile of proposed developments it is increasingly common for projects to end up at Public Inquiry. TNEI always look to provide robust technical services to ensure that the assessments are defensible throughout the planning process and at Public Inquiry if and when required. ...

  • Traffic noise exposure usefully assessed by END digital maps

    Digital noise maps developed under the EU’s Environmental Noise Directive (END) are a useful way of assessing traffic noise exposure for local residents, according to a recent Swedish study. The END maps could also be used to standardise noise exposure information in noise and health research. Environmental noise, from sources including road, rail and air traffic, not only causes annoyance ...

  • Loss of healthy life due to UK noise exposure valued at €1.34 billion

    Exposure to environmental noise levels above recommended levels results in 1169 cases of dementia, 788 strokes and 542 heart attacks every year in the UK alone, new research suggests. Valuing a year of healthy life at £60 000 (€74 002) means that these health impacts together have a ‘cost’ of £1.09 billion (€1.34 billion), the study’s authors conclude. ...
