  • Road traffic noise in downtown area of Tehran

    Noise pollution is by now worldwide recognized as a major problem for the quality of life in urban areas. Vehicular traffic is the most important source of the environmental noise pollution in these areas (Zennin et at., 2001; Suksaard et at., 1999; Arana and Garcia. 1 998. The increasing in the population and in the number of circulating vehicles has led to an increase in the noise pollution but ...

    The necessary data is: External source/internal source/airport options: This is the External/internal/airport option. External means a noise source placed out of a building (for example, a vehicle engine). External surface (m2): In the internal ...

  • What is Long Term Noise Monitoring?

    It might sound simple, but long term noise monitoring can mean different things to different people. There is no standard definition for what long term noise monitoring is, but here is a summary that covers the basics. I first presented this presentation at the IOA Eastern Branch meeting and wanted to share my thoughts on what classes as long term noise monitoring. I’ll also discuss ...

  • The Vienna airport mediation: point of view of the Vienna Ombuds-Office for Environmental Protection

    A history of increasing citizen opposition to the continuous increase in aircraft traffic and associated noise around Vienna airport came to a head because neither the airport authority nor the local authority consulted local interest groups about plans for a third runway. Eventually, the airport operating company decided to address public concerns and set up an environment mediation process. The ...

  • Entropy approach for mitigation of environmental aviation impact and airport capacity increase

    The implementation of the operational procedures to reduce aircraft noise and engine emission in the airport vicinity was under consideration in the paper. Emphasis was put on optimal aircraft operational procedures for noise and emission reduction taking into account interrelations of aircraft noise and engine emission. The task of minimising of aircraft noise impact and engine emission ...

  • 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 ...

  • 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 ...

  • A Good Night’s Sleep: The Impact of Noise

    When you’re trying to get a good night’s sleep, noise can impact severely on your efforts. In fact, some people need 100% quiet before they are able to drift off to sleep – proving silence really is golden when it comes to bedtime. If you sleep in a noisy environment, it ruins the quality of your slumber and leaves you feeling tired and dissatisfied, according to the National ...

  • Continuous noise monitoring for environmental application

    The increasing awareness of the public of environmental issues such as CO2 emissions, carbon footprints and waste recycling has brought the issue of environmental noise to the fore. Many of the demands of modern society result in the creation of noise sources such as larger airports, additional power stations and higher road traffic levels. In addition to this, the expansion of towns and cities, ...

  • Noise and its Link to Mental Health

    Today marks World Mental Health Awareness Day, and it’s one of the most important awareness events of the year. In the last few years, mental health awareness has dramatically improved, meaning that people who for too long have suffered in silence, are now getting the help and treatment they need. Several recent studies have shown a strong link between exposure to excessive noise levels and ...

  • Accelerating with Bugatti

    When the Bugatti Owners’ Club established itself in 1929, its members didn’t really have too much to worry about when it came to issues such as road congestion and noise. But just as cars have moved on with the times so has the Club. The Club applies a strict noise level threshold for competing cars at their renowned meetings on Prescott Hill near Cheltenham, ...

  • Does Noise Pollution cause stress?

    In October 2018 the World Health Organisation (WHO) published their findings from an international investigation into how much noise affects us, including asking 'Does noise pollution cause stress'. It concluded it is one of the top environmental hazards to both physical and mental health and well-being in the European Region. Noise pollution can be defined as unwanted or excessive sound that ...

  • Bird Problems Cause Dangers at Airports. Here is Why

    Birds commonly have a basic set of behaviours, within an airport you can encounter 3 basic bird behaviours: Birds fly in flocks. They will rest in open unused areas, which are the exact habitats found around many airports. They migrate south for Winters and North for Summers. These behaviours become problematic for airports because they have to spend a lot of ...

  • On the application of partial barriers for spinning machine noise control: A theoretical and experimental approach

    Noise reduction by barriers is a popular measure for environmental protection in both urban and rural areas. A barrier, which intercepts the direct path of sound from source to receiver, is frequently used to protect noise sensitive receivers from land transportation noise radiating from highways, railway lines, industrial complexes and airports. This consists of interposing a heavy non-porous or ...

    In the railway case, we shall calculate the noise level in a similar way. For airports, we shall use the next equation Leq=Leq(300m)-20Log(r/300) where Leq(300m) is the noise level at 300m from the airport. This model performs satisfactorily for simple sound ...

  • Tackling Office Noise – The Sound Investment

    Open offices or shared offices can offer great benefits in terms of communication but they can also present challenges. We’ve all had problems with noise in the office - the incessant chatter of your colleagues ruining your concentration; people shouting over you when you are trying to have a conversation on the phone; perhaps even maintenance or construction work going on next door. ...
