  • 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 ...

  • 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 ...

  • 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 ...

  • 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. ...


  • 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 ...

  • Low cost fan noise attenuation in the power industry

    An article about the application of our Quiet Fan technology (QFt) to reduce the noise from large fans in the power industry has been published in Power Engineering International. The journalist suggests that the widespread adoption of the technology in this industry could reduce both capital and running costs very substantially ...

  • Noise in the printing industry: Safeguarding the hearing of workers

    Why failing to monitor noise levels could open your company to lawsuits Noise at work might be synonymous with construction and manufacturing industries but it can also be a significant problem in the printing trade. Failing to monitor and control noise levels in the printing industry can result in workers suffering from ...

  • 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 ...

  • Queensland Rail – An example in effective noise mapping and noise control implementation for existing rail operations

    There is an increasing trend in the world today to model noise impacts of city-wide infrastructure such as rail, road and industrial activities.  This is particularly true of the European Union, which sought to produce an integrated approach across member states to predict city-wide long term average noise levels. The outcome of such an exercise usually results in production of noise ...

  • On the application of partial barriers for spinning machine noise control: A theoretical and experimental approach

    Noise reduction by barriers is a popular measure for environmental protection in both urban and rural areas. A barrier, which intercepts the direct path of sound from source to receiver, is frequently used to protect noise sensitive receivers from land transportation noise radiating from highways, railway lines, industrial complexes and airports. This consists of interposing a heavy non-porous or ...

  • In-situ noise level mapping for vehicle floor carpet

    Noise level mapping of test vehicles' floor carpets was undertaken for three frequency bands, that is, low-(2,000 Hz) to compare noise control treatment performance and effectiveness. On-road tests including idling conditions and constant speed tests of 40, 60 and 80 kph were undertaken. Noise level contour maps indicate that the luxury class test vehicle ...

  • 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 ...
