  • Wind Energy Production Estimates: Moving Beyond Time Averages

    No need to be a statistician to see that averages are often useful to compare different things. And yet, they often fall short as a true measure of performance. For instance, we use averages to compare the current weather against the climate normals or to get a sense of how our favorite sport team or player is doing. Team (player) statistics are a concise way of combining the scores from many ...

  • The Investigation of Noise Attenuation by Plants and the Corresponding Noise-Reducing Spectrum

    As noise pollution is becoming more and more serious, many researchers are studying the noise attenuation effect provided by plants. This article examines six kinds of evergreens as research subjects so as to compare the different arrangements and densities of plants and their effect on noise attenuation. The authors studied the relationship between each of the plant’s characteristics (the ...

  • Noise mapping of industrial sources

    Noise is often one of the environmental variables where it seems more difficult to guarantee full compliance with legal limits in complex industrial situations and/or in other multi-source environments. This paper describes the application of noise mapping techniques to industrial sources, such as factories, power plants, wind farms, showing the potential of its use, both at the design stage as ...

  • Environmental Noise (Booklet)

    About this booklet This booklet deals with environmental noise − for example, noise from industrial sites, road and rail traffic, airports and fairgrounds. It does not cover related issues such as building acoustics, building vibration or domestic noise. Neither does it cover human response to vibration nor industrial uses of sound and vibration measurements. Please contact ...

  • What are the 4 Different Types of Noise?

    Noise comes in all shapes, sizes and sounds. It’s part of our everyday lives but before you can accurately measure it, you need to know what the different types of noise are. Here’s my advice. Whether it’s the innocent beep, a plane flying overhead or heavy machinery in your workplace, you ...

  • Is a background noise survey worth doing? - Case Study

    As a plant owner or designer you will logically try to keep construction costs down wherever possible. So noise control features can easily be sidelined as an “optional extra” to be added later if the need arises. You might also be confident a new industrial plant will comply with all regulations on completion, but that doesn’t mean a future neighbour won’t complain about ...

  • VIBRATION NOISE & ITS IMPACT ON HUMAN HEALTH

    Vibrational Noise is one of the major Environmental problems in Industrial Plants. The Noise Study under taken in Chinese Unit no.4 of Thermal Power Station (TPS) Jamshoro. The level and Frequency characteristics of the prevailing Noise recorded in detail, at Basement Area Feed Pumps, Turbines, Boilers, F.D.F, I.D.F & Compressors, and found that the level of Noise is higher at Boiler House and ...


  • BS4142 Noise Impact Guidelines Are Beefed Up

    There has been an interesting update come across my desk this week relating to the BS4142 noise impact guidelines. Now, that may not sound the most exciting update in the world but for anyone who works in environmental noise, planning or development they need to sit up and take note. The British Standard (BS) 4142 guidelines currently determines the potential noise impact on residential ...

  • Development of Low noise landfill gas flare

    Summary: Increasing requirements of the environmental standards and planning permission conditions create more challenges to the equipment providers. Environment Agency guidance demands low emission levels and local planners put low noise levels in their conditions for landfill sites. Achieving both at the same time with conventional equipment was found problematic. Biogas Technology has ...

  • Case Study: Industrial Site Noise Monitoring

    Environnement S.A., based outside Paris, France, is a cutting edge company in the environmental quality industry. Environnement S.A.s innovations over the years have supplied private and public organisations alike with the tools and know-how to detect, measure and ultimately limit the impact of industry on the natural world. In the summer of 2003, Environnement S.A. approached Brüel & Kjær for ...

  • Noise impact on human health and its control

    Noise can be termed as unwanted/undesirable sound, because of its adverse effects in our living and working environment .Unfortunately a large number of people work in Industrial plants, where the Noise level found consistently high, and the exposure takes place regularly for about 8-10 hours a day, year after year, the effects cease to be temporary & even permanent hearing loss, rather than ...

  • Autonomous data acquisition system for Paks NPP process noise signals

    A prototype of a new concept noise diagnostics data acquisition system has been developed recently to renew the aged present system. This new system is capable of collecting the whole available noise signal set simultaneously. Signal plugging and data acquisition are performed by autonomous systems (installed at each reactor unit) that are controlled through the standard plant network from a ...

  • Application of H-infinity hybrid active controller for acoustic duct noise cancellation

    This paper describes the principle and application of a hybrid robust active noise controller (ANC) for reducing broadband noise in acoustic ducts. The proposed ANC system consists of an adaptive controller with filtered-x least mean square (FXLMS) algorithm and a feedback structure with robust synthesis theory for obtaining robust performance and stabilisation. In an active control structure, ...
