  • 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 ...

  • 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 ...

  • Pollution

    Pollution can take many forms. The air we breathe, the water we drink, the ground where we grow our food, and even the increasing noise we hear every day--all contribute to health problems and a lower quality of life. Find out about the environment ...

  • 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. ...

    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 ...

    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 ...

    Print image.- This command send a pixel-by-pixel image of the program window to the printer. To print with Print image command, you must first display that information on the program window and then print with this command. This command is by far the easiest way to print from your application.  Because it may ...

  • 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 ...

These images will contain the background picture and the simulation results.   Many programs, computer applications and word processors (AutoCad, 3d Studio, ArcView, MS Word,...) import BMP files. You will be able to load images generated by ...

  • 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 ...

  • 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 ...

  • Measuring Road Traffic Noise

    As part of an overall measurement programme to monitor road traffic noise in Århus (Denmarks second largest city), the Local Authority set up a noise measurement station on one of the major approach roads to Århus Harbour. This noise measurement station continually measures noise levels and can give a round-the-clock picture of noise level variations. Like most other districts, Århus Local ...

  • Urban Noise Monitoring in Madrid

    Dynamic mapping helps Madrid improve the quality of life for her citizens and visitors alike. With its 3 000 000 inhabitants and 2500 km of streets, Madrid is an excellent example of what can be done to improve human comfort related to urban noise. Since the late 60s, Madrid City Council has been working on noise problems. During this period, global environmental analysis has focused on how ...
