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.
Vibration testing is is used for aerospace and defence testing, ground transportation, transport simulation, package testing, altitude simulation and more. Our comprehensive range of LDS electrodynamic shakers are designed for vibration testing of devices of any size - from a semiconductor component to a complete satellite system, to see how it will stand up to real-world conditions. With an LDS vibration test system your shaker, power amplifier, vibration controller and even environmental chamber are not only...
Environmental noise is unwanted sound and vibration coming from a plethora of sources, among them industrial plants, road and rail traffic, construction work, and aircraft. Add to these sports events, shooting ranges, leisure parks, etc, and you have noise from many different sources, each with different characteristics and posing specific problems for the professionals who have to assess them. The way the problems are dealt with differs immensely from country to country and is very much dependent on culture,...
The water and wastewater industry uses a large number of pumps of all sizes and ratings, along with their associated driving motors, and they are often run continuously. Monitoring the health of their bearings using vibration sensors enables faults to be detected early, reducing unplanned maintenance shutdowns and supply interruptions.
Typical locations where vibration sensors can be fitted include vertical pump upper and lower bearings, horizontal pump and compressor inner and outer bearings, and thrust bearings...
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.
Traffic noise impacts millions of people at home and at work. Traffic noise can impact your ability to work, learn rest, play, relax, and sleep. This form of noise can also lead to mental and physical health concerns. The noise is dependent upon such issues as: Traffic volume. Traffic Speed. Vehicle Content. Road Surface. Surrounding Area.
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 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.
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...
State of the art noise monitoring systems; Modern noise monitoring systems offer a wide range of advanced features and come with software that can analyze and structure long term measurements data efficiently. A complete noise monitoring system consists of one or more noise monitoring terminals, a noise server and work stations for presentation, post processing and reporting.
Noise emission values are increasingly becoming marketable items for machines, equipment and appliances - low noise emissions directly relate to lower noise exposure for product users and bystanders. Retail customers, both private and corporate, appreciate this relationship and are, therefore, more aware of noise emission declarations on goods when deciding their purchases.
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.
Traditional Field Pass-by measurements are still the only way to certify a vehicle for exterior noise emission during operation, but Indoor Pass-by provides an extremely powerful and repeatable method of troubleshooting exterior vehicle noise in the controlled environment ofan anechoic chamber.
Noise ordinance covers the monitoring of noise in major urban areas in the US. Common complaints from residents include: Barking dogs, Noisy neighbours, Loud music, Construction noise, Industrial noise, Transportation noise.
With a single TROMINO®:

- ReMiTM, ESAC, SPAC, other passive and active spatial correlation methods
- Vibration monitoring (e.g. UNI 9916, DIN 4150)
- Full modal analysis of structures (both passive and active)
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.
Norsonic is a world-leading supplier of sound measuring equipment for the motorsport industry. We have a long experience in supplying sound measurement solutions for racetracks, ranging from single noise monitors to large multichannel monitoring solutions with sophisticated reporting system.
Power plants are expected to operate 24 hours per day, 7 days per week. Downtime and equipment derating (when a generator fails to deliver power at its rated capacity) can cost a power plant thousands of dollars per hour. The cost of replacing failed equipment is also extremely high. Vibration analysis by itself is not enough to anticipate catastrophic failures. Oil analysis is often able to detect problems at a much earlier stage than vibration analysis. This is why more and more power plants are bringing oil...
Workplace noise monitoring is an interesting subject that can appear complex, but it is always worth remembering what you are trying to achieve. This can be summarised as: ““Minimising or avoiding the risk of noise-induced hearing loss in the workplace to comply with local, noise-based, legislation”” Such legislation is usually based on a European Directive that is then modified to suit the needs of each particular country. For example, in the United Kingdom, the ‘The Control of...
Real time monitoring of structures is an excellent field of application for wireless sensor networks. ADVANTICSYS has provided solutions for the monitoring of structure in different fields, from bridges, where the vibration has to be controlled both in the construction and operation phase, to cultural heritage buildings with their structural integrity under risk.
