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.
Noise control in industrial halls is essential to ensure a non-harmful environment for the workers and limit the immissions caused at the neighbouring buildings. Check out how CadnaR enables you to model and calibrate your machines, calculate and evaluate noise at the workplaces and assess measures to acoustically improve any situation at hand.
Tunnel ventilation systems are designed to enable a sufficient throughput of air to be maintained to ensure a safe operating environment for users. These systems consume large amounts of power and need to be operated as efficiently as possible. To do this it is necessary to know the effectiveness of the system in terms of air flow and direction developed within the tunnel. The TunnelTech 301 is a single point ultrasonic flow monitor that is unaffected by traffic flow and sound reflections. It is designed to...
"Good acoustics" is usually the target in room acoustics. The meaning of this depends on the type of room and the intended use. Rooms for musical presentations need a good sound quality at as many seats as possible while lecture halls demand good intelligibility of the teaching person. In case of open-space offices a productive working environment should be ensured. This can mean a focused individual work or a good communication between workers within the same team. CadnaR offers the tools to efficiently handle...
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.
Acoustic theory for heterogeneous system should yield a relationship between some measured macroscopic acoustic properties, such as sound speed, attenuation, acoustic impedance, angular dependence of the scattered sound, etc., and some microscopic charact
Data centers store and protect such valuable digital information as bank accounts, streaming movies, websites, libraries, healthcare data, and government statistics. All of those computer electronics are vulnerable to corrosion caused by air pollution.
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...
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.
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.
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.
Batch mixing generally refers to mixing processes in vessels and ITS tomography instrumentation provides a tool to understand, optimise and control mixing. Tomography sensors take data from between 200 to 2,400 measurement points in a single snapshot, thus providing a sound basis to monitor changes in concentration of different materials and so quantify mixing. Sensors can be retrofitted through using probe based instruments, scanning the z-axis (which usually presents the key challenge to effective mixing)....
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.
Key to any Hydrographic survey is tidal data and Valeport offer tide gauge options for both shore based and offshore / seabed applications together with telemetry packages for secure data transfer.
Echo sounders, both single and multi-beam need sound velocity data to correctly produce depth measurements. Valeport offer the largest range in sound velocity sensors and profilers that have world beating accuracy.
If simple, small boat echo sounding is required with single or dual frequency transducers and interface...
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.
Occupational noise is one of the most overlooked risks in the workplace. Ignoring this hazard can result in fines or prosecution from the Health & Safety Executive. You are also open to action from Personal Injury Lawyers seeking compensation for Industrial Deafness Claims. Why? Exposure to excessive noise levels can cause noise-induced hearing loss or tinnitus. Hearing damage is irreversible, so it is vital to ensure you are protecting your employees and your business.
In the UK from the 6th April 2008 the Control of Noise at Work Regulations apply to the entertainment and music sectors. Applying these new regulations is a challenging task as it requires a significant shift in both attitude and practice across the industry.
Our noise measurement instruments are used at high profile circuits and venues around the world, helping owners, operators, teams and officials comply with noise limits and regulations. With a range of noise measurement tools including drive-by test systems with permanently installed and portable monitors for continuous measurement of vehicles, to handheld sound level meters for pre and post race scrutineering, we can help you monitor and control your noise levels on track, in the pits and in the surrounding...
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.
