A holiday from noise pollution

Tourism is one of the fastest growing economic sectors in the world and offers significant benefits, but among the many challenges the industry faces is protecting the local population, environment, and the travellers themselves, from excessive noise. The modes of transport (especially planes and cars) and mass arrivals at airports, railway stations, and ports and harbours, mark just the ...

Principal Noise Pollution Control

Sources of noise in industrial machinery and processes are : Rotors, Gears, Turbulent Fluid Flow, Impact Processes, Electrical Machines, Internal Combustion Engines, Pneumatic Equipment, Crushing, Blasting, Pumps and Compressors. The most desirable method of controlling a noise pollution is to minimize the noise at the source. This generally means modifying existing equipment and structures or ...

Is The `Beep` Noise Pollution?

It is rare these days that you can be somewhere without noise pollution intruding on some level. Many natural noises may be welcome; a dawn chorus or waves breaking on the beach, but when it comes to man-made decibels it’s a different matter. Never mind the sounds of cars, ring tones and other noises that we take for granted, have you ever noticed how utterly surrounded we are by the humble ...

Noise pollution: an overview of management strategies

Noise pollution is one of the most widespread environmental problems. However noise is a very complex issue, not easy to tackle at all. Main difficulties to deal with are the fact that perception of noise is often subjectively and culturally dependent and that its health consequences are not easy to determine. This paper first analyses the different sources of noise and their health effects. ...

Canarina CUSTIC software · background noise · ambient noise pollution · commands 13

Bitmaps and scanned maps must be loaded into memory and then adapted to the program scale (we will make use of the Scale command). The X-Axis width (meters) in the program window can be easily changed to be able to compare both images (simulation results and background maps). Then, the X-Axis width (in meters) of the imported map and the X-Axis width (in meters) of ...

Noise Pollution – More Than Just an Inconvenience

A raft of new global studies are all pointing to how noise pollution can seriously affect your health – and you don’t need to be living directly under a flight path to be affected. Separate studies carried out over recent years claim to have found links that noise pollution can affect everything from your waist size to the weight of unborn babies and even the recovery rate of ICU ...

Links between noise and air pollution and socioeconomic status

Air pollution and noise pollution have a negative impact on all of society — but some groups are more affected than others. Lower socioeconomic status is generally associated with poorer health, and both air and noise pollution contribute to a wide range of other factors influencing human health. But do these health inequalities arise because of increased exposure to pollution, increased ...

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 ...

Evaluation and analysis of environmental noise pollution in the city of Erzurum, Turkey

Noise pollution and its influence on the environment and life quality of human beings is a hot topic in scientific research. A study has been carried out to determine the level of noise and its sources in the city of Erzurum located in the east of Turkey. Noise measurements were taken in the morning, at noon and in the evening to determine noise pollution all over the city, particularly motorway ...

All the points of the XY-plane will be to a zr height. The zr value is chosen by the user before the calculation. We will be able to make many calculations considering different plane heights. The different plane heights will be determined by the user (zr values). In this way, the physical form of the noise power can be studied. Example: Calculation in ...

Mitigation measures to minimise traffic–generated noise pollution in Metropolitan Kuwait

Forty representative roadway locations were randomly selected for monitoring traffic flow and noise levels. At local streets, equivalent noise level (Leq) ranged between 56 to 71; at collector streets traffic areas 70 to 83; at arterial roadway 75 to 86 and at freeway roadway areas 75 to 88 dBA during day and night time respectively. Consequently, the level of noise pollution from traffic even at ...

Accurate and efficient prediction of acoustical performance of noise barriers against transport noise pollution

An improved acoustical wave propagator (I_AWP) technique with high-order absorbing boundary technique is introduced to evaluate the acoustical wave interaction for noise barriers, providing the dual benefit of preserving high numerical accuracy (boundary conditions have been properly treated) and obtaining high computational efficiency (using a larger time step in the calculation). The aim is to ...

Noise in Europe 2014

Noise pollution is a growing environmental concern. It is caused by a varied number of sources and is widely present not only in the busiest urban environments, it is also pervading once natural environments. The adverse effects can be found in the well-being of exposed human populations, in the health and distribution of wildlife on the land and in the sea, in the abilities of our children to ...

Cloud computing for noise monitoring

ABSTRACT Cloud computing is the use of computing resources that are delivered as a service over the Internet. This means that software, hardware and network resources are centrally managed. The ubiquitous availability of high-capacity networks and reduced cost of both client and server hardware have led to a tremendous growth in cloud computing. The concept gives a huge benefit for ...
