  • 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 ...

  • Canarina CUSTIC software · industrial noise reduction · commands 2

    Due to the features of the software that allows to simulate the process of noise pollution immediately, the numeric simulation is carried out with a remarkable speed. You create the graphical interface for your pollutant sources by drawing point sources in a graphical way. You create the simulation process by drawing point sources on the CUSTIC window. Next, you set properties for the point ...

  • Industrial Noise and Vibration: High-speed balancing - Case Study

    Dynamic balancing of rotating elements is an important aspect of the manufacture and the repair of any turbomachinery. A rotating element that is out of balance can cause major operational difficulties, which may prevent the timely start-up of a facility. Furthermore, the unbalanced element can cause internal damage that will rob a machine of its design efficiency, reduce machine reliability, and ...

  • CR:243/4 noise pole – industrial power station case study

    “Before the Cirrus System was installed we could never investigate noise complaints properly because the data from the time of the complaint was not available in retrospect. We needed noise monitoring instruments that would store data continuously, with software to interrogate the monitors and download data, to give us a complete history of the noise levels at our boundaries. We have ...

  • Prediction of noise from track systems

    A practical approach is presented for the prediction of noise level generated by a track system at the design stage of a tracked vehicle. Rayleigh's surface integral is adopted for relating the acceleration of a track link chain in the time-domain to the radiated acoustic pressure of the exterior noise. The sound pressure levels of the noise generated by the vibrating track system are calculated ...

  • Continuous noise monitoring for environmental application

    The increasing awareness of the public of environmental issues such as CO2 emissions, carbon footprints and waste recycling has brought the issue of environmental noise to the fore. Many of the demands of modern society result in the creation of noise sources such as larger airports, additional power stations and higher road traffic levels. In addition to this, the expansion of towns and cities, ...

  • Reduction of roof rack noise and vibration

    The noise and vibration design of automotive add-on component roof rack was investigated. Different modification options were evaluated which include mounting location alteration, mounting damping change and material revision. Results from experimental modal analysis and sound pressure spectrum measurement in a wind tunnel indicate the direction of design modification for reduction of the roof ...

  • Recent research on vehicle noise and vibration

    Vehicle noise, vibration and harshness (NVH) is usually among the top five attributes in terms of its priority in the design of automotive vehicles. Its priority in other types of vehicles (e.g., aerospace) is also important. Like other attributes of safety, performance, dynamics, fuel economy, NVH has to be considered closely in the design process. This manuscript presents a summary of recent ...

  • What is Long Term Noise Monitoring?

    It might sound simple, but long term noise monitoring can mean different things to different people. There is no standard definition for what long term noise monitoring is, but here is a summary that covers the basics. I first presented this presentation at the IOA Eastern Branch meeting and wanted to share my thoughts on what classes as long term noise monitoring. I’ll also discuss ...

  • 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 ...


  • 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 ...
