By implementing a noise and vibration monitoring system, the impact of construction site activities can be managed by: Complying with legal requirements relating to public health sanctioning the absence of appropriate precautions to limit abnormally high levels of noise and vibrations. Taking environmental quality considerations into account (HQE approach). Limiting noise and vibration pollution with the comfort of neighbouring residents in mind. Enabling companies in the public works and construction industry to...
Noise has become the primary source of environmental disturbance. In 2002, the European Union took decisive action in the form of directive 2002/49/CE relating to the assessment and management of environmental noise. Through the use of strategic noise mapping, every urban community must implement an action plan to combat noise pollution. The monitoring of noise levels in urban environments is therefore an essential factor.
Certain leisure activities, and motor sports in particular, are a source of elevated noise levels. They cause significant disturbance for nearby residents, particularly as such sites are being developed in increasingly densely populated urban areas.
Wind farms must be developed in such a way that they become a part of the environmental lanscape. To this end, public authorities use standards and regulations to impose limits on the noise levels generated by such installations.
Industrial sites are subject to regulations that limit sound and vibration levels at their perimeter and with regard to third parties. The taking of measurements at intervals remains one of the most frequently used methods of evaluating the noise and vibration levels of such sites.
Air traffic is the source of several forms of disturbance to the surrounding area, including, in particular, noise pollution. Local residents in the vicinity of an airport are the most severely affected and are very conscious of the aircrafts` flight paths and the impact on their day-to-day living conditions.
In a process unique to the mining industry, mineral ore must be extracted and conveyed to a means of transportation in a challenging environment. This involves the use of high-power fixed and mobile equipment with complex kinematics. The entire process is carried out in cyclic and variable operating conditions with significant safety and accessibility constraints. Mining operations are also a source of noise and vibration pollution both for site workers and people in the surrounding area.
The paper industry depends upon a continuous industrial process in which the paper machine is the central factor. This system is based on several variable speed rollers mounted on roller-bearing blocks, and damage to a single block can be enough to shut down production for several hours.
The infrastructure required by the iron and steel industry is considerable, and includes a variety of rotating machines such as pumps, fans and rolling mills. Processes and operating conditions vary according to the product worked, and may involve cyclic operations, complex facilities, and stringent security and accessibility constraints.
As a major source of renewable energy, wind turbines are continuing to experience exponential growth, with a production capacity that is doubling every three years. Reliability and the optimisation of maintenance have become major economic challenges for wind turbine operators.
The nuclear industry must increase the availability and reliability of its power stations whilst ensuring that a high level of safety is maintained. The principal weak points in achieving this objective are the industry`s systems and components.
The oil and gas industry requires major infrastructure in terms of refineries and offshore extraction platforms which operate continuously. A large number of essential rotating machines, structures and piping networks are subjected to high levels of demand in a difficult environment, leading to the potential for breakage.
