CadnaA is an excellent tool for the calculation of noise maps and for Strategic Noise Mapping according to the EC Directive on Environmental Noise. A great number of users value its richness in features, calculation speed and last but not least, usability. Numerous noise maps of cities and even entire countries have been calculated and are calculated using CadnaA.
Road and Railway Noise
CadnaA is the leading software for the calculation, assessment, prediction and presentation of traffic noise, with many thousands of kilometers already modelled worldwide. Roads, parking lots and railway lines can be modelled very conveniently to calculate the noise immission in the vicinity and to derive decisions about further noise reduction plans. Efficient workflows are used to tackle specific problems, such as the optimization of different noise reduction measures or comparisons of...
We are proud to develop the most powerful software for the calculation, assessment and presentation of outdoor noise. Our software solutions for the calculation and assessment, prediction and presentation of environmental noise exposure are powerful, yet easy to use. Whether your objective is to study the noise immission of an industrial plant, of a commercial center including a parking lot, of a new road or railway scheme or even of entire towns and urbanized areas: CadnaA is designed to handle all these tasks.
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.
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.
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.
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.
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.
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.
The increase in housing stock required by the government is leading to developments being considered in a wider variety of locations and can provide challenges in assessing and agreeing levels of acceptable noise and vibration exposure. With the introduction of the National Planning Policy Framework (NPPF) and the Noise Policy statement for England (NPSE) clients are faced with rapidly changing local authority requirements.
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.
Monitor environmental status with greater clarity. This allows you to react quickly to emerging situations, determine the source of issues before compliance limits are reached and enables you to take care of asset health to optimize your operations.
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.
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.
One of the largest acoustic consulting firms in Australia was engaged by the New South Wales Department of Planning & Industry to conduct wind farm noise assessments. The goal was to perform a specialist, independent acoustic compliance audit of three major wind farms located near Canberra, Australia’s capital city.
The objective of the study was to conduct a detailed noise assessment at residential dwellings near to the wind farms. Three wind farms near Canberra, Australia, were investigated.
XL2 Sound Level...
The Data Explorer PC software for the XL2 Sound Level Meter now includes a series of professional tools for detailed analysis of low-frequency noise (LFN). The graphical representation of time varying frequency components offers an efficient process for identifying the presence and level of LFN. Also the associated high quality audio recording supports further correlation with the objective measurement data.
The new features are particularly useful in the calculation of immission levels which is defined as the...
Construction can be a industry where high noise levels are common and where both occupational and environmental noise monitoring may be needed. The measurement and monitoring of noise from construction sites can be carried out using a range of different instruments depending upon the time over which the measurements need to be made.
Cirrus Environmental can supply a range of noise measurement options for construction and demolition noise applications. These range from handheld sound level meters for taking noise measurements through semi-permanent noise monitors to permanently installed noise monitoring systems, all designed to be fully weather protected for reliable long term operation.
Airport noise monitoring often requires a combination of short term measurements to gather information along with long term measurements to maintain compliance with agreed noise levels. Cirrus Environmental has a range of noise measurement instruments that have been purpose designed for these tasks along with the NoiseHub software package.
