  • Queensland Rail – An example in effective noise mapping and noise control implementation for existing rail operations

    There is an increasing trend in the world today to model noise impacts of city-wide infrastructure such as rail, road and industrial activities.  This is particularly true of the European Union, which sought to produce an integrated approach across member states to predict city-wide long term average noise levels. The outcome of such an exercise usually results in production of noise ...

  • On the right track

    High-speed train manufacturer, CAF, rely on world-class beamforming technology to reduce the noise generated by their trains – helping to make high-speed trains a more viable option for travellers and operators alike. Because of its relatively low levels of CO2 emissions, train travel is considered one of the ...

  • Environmental Noise

    Introduction The ability to hear sounds is a sensory function vital for human survival and communication. However, not all sounds are wanted. 'Unwanted sounds', for which the term 'noise' is normally used, often have their origin in human activities (mainly transport, industry and households). This article addresses environmental noise ­ also referred to in the scientific literature as ...

  • Weather Data for Noise Monitoring

    “Weather conditions are the single largest variable factor in how sound travels over large distances,” says Steve Bilawchuk principal partner and engineer at ACI Acoustical Consultants Inc. “Wind speed and wind direction are of crucial importance.” ACI is an acoustical engineering consulting company based in Alberta, Canada, which uses ...

  • Environmental Noise (Booklet)

    About this booklet This booklet deals with environmental noise − for example, noise from industrial sites, road and rail traffic, airports and fairgrounds. It does not cover related issues such as building acoustics, building vibration or domestic noise. Neither does it cover human response to vibration nor industrial uses of sound and vibration measurements. Please contact ...

  • Effect of moving sand as a ballast contaminant on rail corrugation: field experience

    Research work on rail corrugation phenomena is mostly focused at trying to explain the mechanism by which these corrugations are formed and to some extent, the environmental consequences represented by the noise of trains passing corrugated sections of track. In this work, it is the effect of environment as a corrugation catalyst that is studied. In certain countries of the Middle East, sections ...

  • Current Trends in Environmental Noise Monitoring in Europe

    Introduction This paper briefly describes the state of the art of environmental noise monitoring development in Europe, including the needs, standards, legislation, data, technology, techniques and tools. This paper will concentrate on the following areas: • How Imagine and the development of ISO 20906 and ISO 1996 affect noise monitoring systems • The need and role of professional ...

  • Reduction of Train Noise Monitored by New Measurement Station

    With increasing passenger and freight traffic, the strengthening of the rail traffic is an important and actual issue. For sustainable mobility, the reduction of noise pollution caused by trains is essential. All involved parties agree on one claim: Increase railway traffic, decrease railway noise! Additional to two already existing stations measuring road traffic noises, ...

  • Sensitivity analysis of simulation model on railway rolling noise prediction

    The railway rolling noise prediction software (RRNPS) is a simulation model for predicting the sound pressure levels during a train passage due to wheel/rail roughness, based on vibration dynamics, contact mechanics and sound radiation modules. Some field validation has been done under European and Australian conditions. Comparisons between simulations and measurements have shown that this ...

  • Identifying Low-Frequency Tonal Noise in Windy and Noisy Conditions - Case Study

    Problem A large LNG gas facility (approximately 300m x 150m) producing 300 000 tons of LNG annually is situated in a terminal area with the nearest populated area at a distance of around 1 km. Within the gas production facility, a low-frequency tonal noise at around 500 Hz is generated causing complaints from nearby neighbours. The tone imposes a more stringent noise requirement on the ...
