  • Aircraft noise valuation studies and meta-analysis

    Aircraft noise has a negative impact on consumer welfare in the regions affected. One of the consequences is that property values decrease. This paper gives a survey of studies from various countries on the relationship between the volume of aircraft noise and the values of dwellings. A meta-analysis is carried out to arrive at a synthesis of these studies and to find factors that explain the ...

    For an external source, the noise level equation is   Leq=LW-20Log(r)-11dB(A)   where r is the distance and LW the source power. However, for an industrial complex, the next equation will be used: ...

  • How does living with aircraft noise affect wellbeing? A study of UK airports

    Airports are associated with air and noise pollution and may, therefore, reduce the quality of life of local people. This study assessed the link between aircraft noise and subjective wellbeing, using data from 17 English airports. The authors conclude that living under flight paths has a negative effect on people’s overall wellbeing, equivalent to around half of the effect of being a ...

  • 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 ...

  • Noise Moinitoring at Toronto Airport

    Running a Caring Business Toronto Pearson International Airport is Canada's busiest airport. The number of passengers passing through its halls is expected to increase from 28 million in 2001 to around 50 million by the year 2020. The area surrounding the Airport has a population of over 4 million. This presents the Greater Toronto Airports Authority (GTAA) with a major challenge to minimise ...

  • Low-noise Parking at Madrid Airport

    With over 34 million passengers, and handling over 360 000 flights annually, Madrid Barajas Airport, Spain is the fifth largest airport in Europe. It is owned by AENA (Aeropuertos Espaoles y Navegacin Area), who manage over 60 airports throughout Spain and Latin America and handle over 160 million passengers each year. On experiencing a growing number of complaints from the neighbouring ...

  • Airport Construction and Aircraft Monitoring example application – CR:243/1 case study

    Project Summary In this application a number of noise monitors were installed to measure the noise from a new international airport both during the construction and also when the airport opened. The noise monitors were located on buildings, in and around the centre of a large city. The Invictus Permanent Noise Monitor was chosen as each location was different and each installation needed ...

  • Noise in the Animal Shelter Environment: Building Design and the Effects of Daily Noise Exposure

    Sound levels in animal shelters regularly exceed 100 dB. Noise is a physical stressor on animals that can lead to behavioral, physiological and anatomical responses. There are currently no policies regulating noise levels in dog kennels. The objective of this study was to evaluate the noise levels dogs are exposed to in an animal shelter on a continuous basis and to determine the need, if any. ...

  • 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 ...

  • Canarina CUSTIC software · noise mitigation · commands 7

    The program window is a XY-plane (parallel to the land surface). A noise source is represented by a small square. In the Status bar at the bottom, we have X and Y coordinate values in meters and data on our environmental system. Point the mouse where you want in the program window and the X and Y values will be shown in the status bar at the bottom. On the left bottom corner, two different text ...

  • 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 ...

  • 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 ...

  • New techniques to determine specific noise for increasing the effectiveness of continuous unattended noise monitoring systems

    Continuous, unattended noise monitoring systems can immediately alert you should noise levels exceed defined criteria. Once alerted to an exceedance, operators can act to return levels to compliance. This approach has two significant limitations. Firstly the operator can only take action after the breach has occurred and therefore systems are only able to inform owners about problems that have ...

  • A study of noise transmission through cylindrical shell using modal truncation approach

    The study of the vibroacoustic behaviour of cylindrical structure like aircraft fuselage requires the establishment of very large models, and the numerical results which can be obtained are often difficult to interpret. On the other hand, the study of simple structures such as cylindrical shells is useful to validate the criteria and tools that can be used to simplify the models of complex ...
