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.
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.
Neighbour Noise, Environmental Noise & Community Noise. Noise nuisance is a growing issue that continues to hit the headlines. Whether it`s noisy neighbours, barking dogs or music events, the need to measure noise nuisance is rapidly increasing.
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.
Completing a Noise Risk Assessment can seem like a big task at first. That`s why our Noise Experts have provided advice based on their years of experience. Find answers to common problems such as "Do I have a noise problem?" and "What do the Regulations require me to do?" We`ve also recommended a range a products to help get you started with workplace noise monitoring.
Before you can determine what design changes are appropriate to reduce the noise emitted by a product, you need to be able to characterise it in terms of: Spectral content: The location of the dominant sources. The relative importance of dominant sources. Noise Source Identification employs a number of tools to perform such a characterisation.

At the core of a Brüel & Kjær system is the PULSE analyzer platform, which provides powerful applications and highly flexible hardware configurations.
A range of noise measurement instruments, all fully weather protected for reliable long term operation, that are ideal for transport noise measurements. Whether it’s for short term handheld measurements or longer term noise monitoring applications, Cirrus Environmental can offer a solution.
In a world where there is a drive for everything to be quieter, vehicle noise measurement and control is a growing application. If measurements need to be made to ISO 5130:2007, which is an internationally recognised standard for vehicle exhaust noise testing, a more detailed measurement needs to be made. ISO 5130:2007 requires three consecutive measurements to ensure repeatability. These measurements are taken at a specified engine speed, or RPM, and the maximum sound level produced during the test is taken.
The Trojan noise nuisance recorder is designed specifically for noise nuisance complaints and neighbour noise monitoring. The Trojan was designed for use by EHO’s and housing associations so we have included all of the functions and features that are essential and removed anything that makes life complicated.
For Industrial Noise Monitoring applications, Cirrus Environmental can supply a range portable, semi-permanent or permanent noise monitors as well as the MK:427 NoiseSensor for integration into existing data logging systems.
Manufacturers of electroacoustic equipment such as loudspeakers, microphones, telephones, headsets, hearing aids, hydrophones, etc., have, for many years, successfully developed new innovative acoustical designs and introduced these into the market in the form of high-quality products.
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...
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.
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.
Environmental noise monitors that connect directly to process measurement and control systems. Many industrial plants have a variety of process sensors strategically placed around their site so that safety, environmental impact and efficiency can be monitored and managed, in real time, from one or more control rooms.
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.
Many industrial operations take place over lengthy time periods and operations often continue 24 hours a day. By implementing a 24 hour noise monitoring system, with real-time communication and alert notification, a plant can demonstrate to the community and regulatory agencies that they are sensitive to the community and prepared to root-cause and correct any problems that may arise.
Industrial noise generated from plants, mills, refineries, shipping docks, utilities, and more, impact the quality of the surrounding community. By controlling and monitoring this noise a community and industry can establish a working relationship that will benefit all. An effective noise monitoring program will allow an industrial site to understand the noise sources and time periods that are causing concerns and then develop a plan for mitigation.
