  • 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 ...

  • Transport noise: the health impacts of noise pollution

    Whilst living in cities, near airports or road and rail links, might prove useful for the commute, the noise levels can sometimes be too much to bear. A growing body of research reveals, transport noise can cause sleep disturbance, cardiovascular disease, elevated hormone levels, psychological problems and even premature death; studies on children have identified cognitive impairment, worsened ...

  • Environmental Noise Monitoring

    The XL2 Sound Level Meter provides the dedicated solution for monitoring environmental noise in industry and communities. It measures levels and detailed spectral information in parallel and stores the data on an SD card for post-processing and reporting. A linear audio file (wav-file) may be recorded for detailed simultaneous analysis. The type approved class 1 sound level meter offers a ...

  • The Battle Against Aircraft Noise

    There is good news for anyone living near or under a flight path of one of the UK’s airports this week. A report out from the Airport Operators’ Association (AOA) shows that UK airports are reducing noise pollution and carbon emission despite growth in passenger numbers. The AOA was keen to publish the report in response to political and ...

  • Students help eliminate noise disturbance

    A team of engineering students, from the University of Windsor, established a consistent noise emission contour of North America’s Windsor-Detroit border in an effort to eliminate transport noise affecting locals at Canada’s largest border crossing.The project – known as ‘Windsor Environmental Noise Mapping Initiative’ (WENMI) – was carried out, using environmental noise calculation and mapping ...

  • Turn down the noise — softening the impact of excess transport noise

    As a major contributor to greenhouse gases, the transport sector figures high on the international climate change agenda. But for many living in cities, under flight paths or near major road and rail links, it's another of transport's by-products that causes most immediate harm: noise. Clearly, transport noise's long-term impacts fall a long way short of the apocalyptic projections for unabated ...

  • Air Quality & Noise Control Conference

    Air pollution is the world’s largest single environmental health risk. Unprecedented infrastructure activities, industrialization and heavy traffic are the main threats which increase the risk of respiratory and cardiovascular diseases. Noise-monitoring stations have been installed across the UAE to control the sound level in the cities. Restrictions were imposed on working hours and the ...

  • Noise Mapping and Planning For Non-Acousticians

    New software is available for those who may not have in-depth knowledge of acoustics but want accurate results of a noise calculation in the smallest amount of time, with the maximum amount of professionalism. SoundPLAN-essential was conceived with this in mind. SoundPLAN-essential is a compact version of SoundPLAN, known for its power, fast data processing and graphics. It is said ...

  • New vehicle noise standards proposed

    After a twenty-year wait, the European Commission has today proposed new standards to cut noise levels from cars, vans, buses and lorries. Reacting to the proposal, Nina Renshaw, deputy director at Transport and Environment, said: “While this proposal is a welcome move in the right direction, it should have gone farther and faster. The vast majority of cars for sale already meet step 1 of ...

  • Reliable Noise and Vibration Measurements in one Device

    Machinery design engineers have to consider both structure-born and air-borne energy emission. The XL2 Analyzer is a single handheld tool that reliably measures both vibration and acoustic noise, providing you all the necessary information you need to optimize the design of your machines with uncompromised Swiss Quality. The XL2 Analyzer is widely respected as the go-to device for ...

  • IMMISmt – monitoring system for air pollution and noise in cities

    IMMISmt is a real time monitoring system for air quality and noise. Based on online traffic data, measurements of air quality stations and weather data, IMMISmt calculates traffic induced emissions, background and total pollutant concentrations as well as noise levels within the streets as, e. g., hourly mean values. To do so, IMMISmt combines various models which are validated and widely used in ...

  • The challenges of conducting noise surveys in urban areas

    Ambient noise surveys crucially establish an information baseline which will enable you to better understand existing noise levels and the additional impact your facility may have on the surrounding community The process is relatively simple in rural areas where the oil and gas industry tends to have well sites and compressor stations located, with only the odd passing train or plane overhead to ...

  • Flying Eurofighter noise mapped by Brüel & Kjær

    Airbus Defence and Space and Brüel & Kjær have successfully completed noise measurements on the Eurofighter jet, to calculate its on-ground noise exposure under different thrust and flight configurations.   The noise measurements were made by repeatedly flying the jet over a Brüel & Kjær data acquisition system collecting data from a 29m diameter array of ...

  • DNV obtains accreditation for noise testing of wind turbines

    DNV announces that its Seattle, Washington, office has been approved for accreditation by the American Association for Laboratory Accreditation (A2LA) for acoustic noise emissions testing on wind turbines. A2LA has granted DNV’s Seattle office accreditation for acoustic noise testing of wind turbines in accordance with ISO/IEC 17025:2005 * for acoustic noise measurements as per IEC 61400-11 ...

  • Commission finally tackles problem of traffic noise

    Traffic noise has suddenly moved up the EU agenda, with the Commission promising to cut noise from cars, vans, buses and lorries within five years. A proposal due later this year is expected to seek to reduce car noise by four decibels and lorry noise by three. The issue of noise has lagged behind EU efforts to cut air pollutant emissions, but a recent study suggesting that the benefits of ...
