  • Principal Noise Pollution Control

    Sources of noise in industrial machinery and processes are : Rotors, Gears, Turbulent Fluid Flow, Impact Processes, Electrical Machines, Internal Combustion Engines, Pneumatic Equipment, Crushing, Blasting, Pumps and Compressors. The most desirable method of controlling a noise pollution is to minimize the noise at the source. This generally means modifying existing equipment and structures or ...

  • Occupational noise - Noise control at the workplace starts with measurements

    We often automatically turn to personal protective equipment in order to restrict noise. Yet there are other solutions. NoiseAtWork software enables us to map the situation quickly. It has been scientifically proven that exposure to noise which exceeds 80 dB(A) causes hearing loss, but lower levels can also cause physical and mental complaints. Noise also has a disruptive effect on communication ...

  • Keep it Down! Controlling Noise in the Workplace

    According to the HSE, over one million employees in the UK are exposed to levels of noise which put their hearing at risk. Noise-induced hearing loss is one of the most prevalent, but often ignored, risks in the workplace and employees must, by law, be protected. Once noise-induced hearing loss has taken place, it is irreversible. Clearly prevention is the most sensible option here as 1 in 7 ...

  • Netherlands’ Mobile Emergency Pumps Provide Rapid Flood Response

    The Western European nation has 20 mobile diesel-driven pumps on standby, ready to assist in national and international emergencies. One of the smallest and most densely populated countries in Western Europe, the Netherlands has nearly 10 million residents who live and work below sea level. Without active water management and primary flood defenses, ...

  • Shredding tyres stops zika virus breeding

    Zika is a dangerous disease threatening millions of people today in southern hemisphere. It is spread mostly by the bite of an infected Aedes species mosquito (Ae. aegypti and Ae. albopictus). These mosquitoes bite during the day and night. Once you get bitten it is too late to do much but what is important is to prevent this mosquito from breeding. Mosquitos typically lay eggs near water because ...

  • Noise Measurement

    Definitions Threshold and criterion levels The threshold level is the A-weighted sound level at which a personal noise dosimeter begins to integrate noise into a measured exposure. For example, if the threshold level on a sound level meter is set at 80 decibels (dB), it will capture and integrate into the computation of dose all noise in the employee's hearing zone that equals or exceeds 80 dB. ...


  • Controlling the timing chain noise in diesel engines

    Timing drive by chain is commonly used in passenger cars especially in diesel engines with double overhead camshafts owing to their numerous advantages compared with belt drive systems. However, one of the important subjects to take into account is the timing chain noise, so-called "meshing noise" that can be perceived by the driver. The manufacturer's efforts to reduce it, are focused ...

  • Controlling the turbocharger whistling noise in diesel engines

    Turbochargers are now commonly used in passenger cars especially in application with diesel engines because of their numerous advantages. The use of this machine greatly improves engine performance, while at the same time allowing pollutant emissions to be reduced. However, one of the important issues to take into account when a turbocharger is used in passenger cars is the whistling noise due to ...

  • Reducing noise levels through engineering controls

      It"s fairly easy to control personal exposure to noise by limiting exposure time or using hearing protectors like ear plugs or ear muffs.  Engineering controls are usually applied to the machinery that produces noise. Imagine a 200 foot x 175 foot manufacturing facility with a 30 foot high ceiling.  In this building are a variety of cut-off saws, grinders, millers and other ...

  • 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 ...


  • Record breaking formula one fan noise control

    Problem: an extract system fan drone creating a potential environmental noise problem. Solution: aerodynamic engineering instead of silencers – in keeping with the Red Bull Technology ethos. The conventional technique used to reduce fan tones like this is a silencer – a large, palliative silencer that doesn’t tackle the source of 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 ...

  • Noise Monitors and Meters

    Sound level meters Description and ApplicationsThe sound level meter is a lightweight instrument for the measurement of sound pressure level (SPL) in decibels. All ANSI-approved meters meet minimum requirements that include an A-weighted network, a slow-response meter characteristic, and a fully graduated scale with measurements ranging from 80 to 130 dBA. The Type II meter is most frequently ...

  • Measuring Road Traffic Noise

    As part of an overall measurement programme to monitor road traffic noise in Århus (Denmarks second largest city), the Local Authority set up a noise measurement station on one of the major approach roads to Århus Harbour. This noise measurement station continually measures noise levels and can give a round-the-clock picture of noise level variations. Like most other districts, Århus Local ...
