Noise monitoring for communities

by Larson Davis, a division of PCB Piezotronics     based in Depew, NEW YORK (USA)

Whether you are in the city, suburb or at a weekend getaway location, noise is an important factor in determining your quality of life or the success of your business.  Many areas have local noise legislation that defines the noise limits that can be produced and experienced during the day or at night.  This noise may be generated by vehicle traffic, aircraft, industrial sites, construction projects, entertainment events, or many other activities.

Noise monitoring solutions for environmental noise and vibration

by Brüel & Kjær Sound & Vibration Measurement A/S     based in Nærum, DENMARK

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, economy and politics. We offer solutions to cover all demands from level checks to in-depth analysis, from measurement or prediction, to post-processing and reporting.

Noise monitoring for airport noise

by ACOEM     based in Limonest, FRANCE

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.

Noise monitoring for the construction industry

Whether you are in the city, suburb or at a weekend getaway location, noise is an important factor in determining your quality of life or the success of your business.  Many areas have local noise legislation that defines the noise limits that can be produced and experienced during the day or at night.  This noise may be generated by vehicle traffic, aircraft, industrial sites, construction projects, entertainment events, or many other activities.

Noise monitoring for airports

by Larson Davis, a division of PCB Piezotronics     based in Depew, NEW YORK (USA)

Airports, small and large, use noise and operations monitoring systems to reduce the noise of flight operations in the surrounding community.  Noise monitoring is generally used to evaluate noise abatement programs and to develop aircraft departure and arrival procedures that minimize the impact of aircraft noise based upon altitude, flight path, and time of day.  Noise monitoring is linked with radar tracking so that specific aircraft can be identified when noise limits are exceeded and so operational requirements can be enforced.
Larson Davis provides noise monitoring systems to airports, consultants, and system integrators with the technology and support to make a successful program.

Sound Instrumentation for Measuring Sound

by Norsonic AS     based in Lierskogen, NORWAY

What is the difference between sound and noise? Clearly more than the loudness only. Although an aircraft is very noisy, a mosquito at night-time can be more than enough to spoil a good night`s sleep. Instead of looking at the loudness only as a criterion for the degree of noisiness, we shall simply regard noise as what it is - viz. unwanted sound.

Noise monitoring for railways and trains

by Larson Davis, a division of PCB Piezotronics     based in Depew, NEW YORK (USA)

Controlling and monitoring railway and train noise in residential and urban areas is a critical function of a railway. The noise generated can be dependent upon the engine, rail cars, rail construction, train speed, and the horn. Modern high speed trains have also created new levels of high frequency noise that create an acoustic disturbance that sounds like an aircraft going by.
