  • 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 ...

  • Weather Data for Noise Monitoring

    “Weather conditions are the single largest variable factor in how sound travels over large distances,” says Steve Bilawchuk principal partner and engineer at ACI Acoustical Consultants Inc. “Wind speed and wind direction are of crucial importance.” ACI is an acoustical engineering consulting company based in Alberta, Canada, which uses ...

  • 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 ...

  • 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, ...

  • HAV mis-measurement – to no standards whatsoever…

    Misunderstanding Hand Arm Vibration monitoring marketing material can put hands and safety policies at risk. Caveat emptor. We are regularly asked about new vibration measurement technology, particularly re the latest hand-held, glove or wrist mounted transducers that are presented as the latest assessment improvements. Whilst they may be useful tools, unfortunately some claims have been ...

  • 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. ...

  • Current Trends in Environmental Noise Monitoring in Europe

    Introduction This paper briefly describes the state of the art of environmental noise monitoring development in Europe, including the needs, standards, legislation, data, technology, techniques and tools. This paper will concentrate on the following areas: • How Imagine and the development of ISO 20906 and ISO 1996 affect noise monitoring systems • The need and role of professional ...

  • 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 ...

  • CR:245/SP Semi-Permanent Noise Monitor Semi-Permanent Noise Monitoring System example application case study

    Project Summary An industrial site in a remote location needed to monitor, measure and control boundary noise levels over the lifetime of a lengthy decomissioning and demolition project. Weather protection and reliability were top of the list for this application due to the remote location. A number of semi-permanent noise monitors were installed with data downloaded remotely over a ...

  • Personal Noise Solutions for Miners

    Throughout the working day, miners are continually exposed to varying levels of noise which can result in hearing loss. For safety reasons it is important to monitor employees’ noise exposure and Cirrus Research has created such a device in the form of the CR: 110A doseBadge. The Cirrus Research doseBadge is the original wireless personal noise dosemeter. It is the ideal tool to carry out ...

  • New techniques to determine specific noise for increasing the effectiveness of continuous unattended noise monitoring systems

    Continuous, unattended noise monitoring systems can immediately alert you should noise levels exceed defined criteria. Once alerted to an exceedance, operators can act to return levels to compliance. This approach has two significant limitations. Firstly the operator can only take action after the breach has occurred and therefore systems are only able to inform owners about problems that have ...

  • Long-term noise monitoring – how a new approach leads to a better result

    Good Neighbours Limit their Noise Impact Long-term noise monitoring has taken place in various applications for many years. Business such as airports, power stations, refineries, mines, etc., may be required to perform continuous noise monitoring to ensure legal operating conditions are not breached, and to demonstrate to local authorities and communities that the business continues to be a good ...

  • 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 ...
