ABSTRACT Cloud computing is the use of computing resources that are delivered as a service over the Internet. This means that software, hardware and network resources are centrally managed. The ubiquitous availability of high-capacity networks and reduced cost of both client and server hardware have led to a tremendous growth in cloud computing. The concept gives a huge benefit for both acoustic ...
Noise monitoring equipment is required for environmental noise applications that need to be monitored over a period of time and where a hand-held sound level meter taking on the spot noise measurements would not be suitable. Noise Monitoring Equipment from Cirrus Environmental The Invictus range can cover any environmental noise application, from short-term monitoring requirements where the ...

The Nova Outdoor Noise Measurement Kit - 24/7 Environmental noise measurement We often get asked about continuous mid- and long-term environmental noise measurement for outdoor sites such as construction sites, outdoor entertainment venues, and for boundary noise assessments. Whilst we have provided several incarnations of outdoor kits which turn our handheld sound level meters into outdoor ...
Since 1970, Cirrus’ mission has been to make monitoring noise simple. More than 45 years later, we thought it was time to look back at our story so far and see what we have achieved. Join us by watching our video, which explores our history and what makes us the noise measurement pioneers that we are today. Cirrus Research plc - Our Story Our Journey from 1970 to 2016 Included Many ...
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, ...
When the Bugatti Owners’ Club established itself in 1929, its members didn’t really have too much to worry about when it came to issues such as road congestion and noise. But just as cars have moved on with the times so has the Club. The Club applies a strict noise level threshold for competing cars at their renowned meetings on Prescott Hill near Cheltenham, Gloucestershire. Cirrus ...
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 where ...
The CR:245 series consists of self contained Portable Environmental Noise Monitors, ideal for short and medium term measurements for applications such as industrial, airport, transport and construction. Both periodic environmental groups and recognised noise events are stored, along with a 7 Day Noise Profile (time history). Operation is very straightforward simply press the start button to ...

Cirrus Environmental has enjoyed a long alliance with John F Hunt Demolition going back over many years, so much so, the company’s Health, Safety & Environmental Department has accumulated almost an historic arsenal of Cirrus equipment that charts the journey of noise monitoring over the years. About John F Hunt Demolition The Essex-based limited company was established in 1982 and ...
Equipment Summary Invictus Environmental Noise Pole Monitor Noisehub Noise Monitoring System Software This is an example of a Boundary Noise Monitoring System that has been built using the Noise-Hub software and Fixed Noise Monitors. A Boundary Noise Monitoring System can be expanded using additional Noise Monitors This type of system is used at Oil Refineries, Power Stations and ...
Cirrus Research will be presenting a number of new and exciting additions to the existing range at the A+A Exhibition in October 2017. On stand 6C51 will be the new doseBadge5 Noise Dosimeter and the Optimus Sound Level Meters which together provide a complete solution for both occupational and environmental noise measurements. A+A 2017 will be the first opportunity for visitors to see the ...
When First Direct Arena opened in Leeds, UK a few years ago, they needed the perfect instrument to ensure that noise levels were kept within the UK’s health & safety regulations, whilst ensuring the best acoustic and entertainment experience for the audience. It was fitting then that a prestigious venue such as First Direct Arena would invest in the latest noise monitoring technology ...
For an external source, the noise level equation is Leq=LW-20Log(r)-11dB(A) where r is the distance and LW the source power. However, for an industrial complex, the next equation will be used: Leq=Li+10Log(S)-20Log(r)-14dB(A) where S is the external surface and Li is the internal noise power. ...
Advances in electronics and acoustics have transformed cumbersome, limiting and often complex meters into dependable, robust and easy to use occupational noise monitors to ensure compliance with the Control of Noise at Work Regulations (2005). Pulsar Instruments offer complete noise monitoring solutions for use in factories, workshops, warehouses, construction and demolition sites, transport, ...

Helicopters and aircraft In this particular area there were quite a few helicopters and aircraft and these were picked up by the Invictus. “You find these days that developers are being asked for more and more studies or evidence over issues such as environmental noise, particularly in rural locations. Some would seem almost comical but it is becoming more the norm to meet planning ...
Looking to buy a sound level meter? You’ll probably see the term “data logging sound level meter” quite frequently. But what exactly is a data logging sound level meter and what does it mean for your noise measurements? Sound level meters have come a long way since Cirrus starting manufacturing their own models in the 1970s. The advances in computing technology has made it far ...
