WHY NOISE IS A PROBLEM
We all know about the affects of pollution, in the sense of carbon emissions, there is a lesser spoken about pollution, noise.
Noise pollution is defined as: harmful or annoying noise.
There have been and continue to be large numbers of studies into the effects of noise pollution on humans, animals and the environment. The major outcomes of these studies are the cause for concern of noise pollution from the aviation industry.
The harmful effects for people include:
- Stress
- Long / Short term Shifted Hearing Thresholds (leading to long term hearing damage or loss of hearing in extreme cases)
- Increased Stress and Blood Pressure Levels (contributing to heart diseases, immune deficiencies, skin disorders, asthma and other stress related diseases)
Whilst effects on wildlife include:
- Reduced Milk Production
- Increased Glucose Concentration
- Decreased Heamoglobin
- Reduced Thyroid Function
LONDON HEATHROW
London Heathrow is the UK’s largest and busiest airports and one of the busiest airports in the world. According to figures released in 2014, London Heathrow:
- Has 2 Runways, 5 terminals and 125 serviceable departure gates
- Serves 180 destinations in 85 countries
- Only 7% of the total flight traffic is domestic, whilst the remaining 93% is all international
- Covers 1,227 Hectares of land
- Carried 1.42 Million metric tonnes of cargo
The 2008 Opening of Terminal 5 (home of British Airways) brought increased flight figures, increased noise and vehicle traffic.
In July 2013, there was a proposal submitted which documents the addition of a 3rd runway, which would have a large impact on flight traffic and the local countryside. Whilst the proposal has not been given the go ahead, it is undergoing revisions.
Heathrow Airport has 4 ‘stacks’, these are air zones where planes continuously fly around in a circular pattern whilst waiting for final landing instructions from air traffic controllers, these stacks are becoming an increasing concern to residents in areas close in proximity. Noise pollution is now affecting people in the 4 Heathrow stacks at Bovingdon, Lamboune in Essex, Biggin Hill in Bromley and Ockham in Surrey.
Increasing Reliance on computers to guide planes into land is now concentrating flight paths in certain areas, often a significant distance from the airport, causing distress to residents who live below those flight paths.
