More than a million people victims of noise pollution

And what if Hell was Noise? Studies have identified the areas most affected by noise pollution. They could have a significant impact on the health of the inhabitants of Paris' suburbs, but a lot has already been done for the comfort of the residents.

Paris-Orly airport transports 32 million passengers a year. That's 200,000 take-offs and landings each year. At night, 1.2 million people in Ile-de-France are concerned by these movements, which represents 10% of the total population of the region. In the Northern area, which includes the airports of Paris Charles-de-Gaulle and Paris-Le Bourget, 1.4 million people could be affected during the day, and 1 million at night by the noise pollution of airport infrastructures. This study is based in particular on areas potentially overflown within 2500 meters. A true mass pollution with insidious effects because invisible, but yet very real.

Noise seriously harms Parisians' health

The subject of the noise is at the heart of a resident's concerns regarding airports and France is no exception. 107 766 years of healthy life are lost every year in Ile-de-France because of these nuisances. Despite the regulatory limit of 55 decibels for exposed areas, according to Bruitparif, the health consequences go beyond the simple inconvenience caused. Beyond the alterations caused to the auditory system, the main effect is the disturbance of sleep. But living in a noisy environment can also provoke cardiovascular disease or cause delays in learning. 
The airports of London, Frankfurt, Paris, Amsterdam and Madrid are among the 20 airports with the highest passenger volume and air traffic, which is expected to continue to grow. Eurocontrol, the organization for the safety and management of civil and military air traffic, provides for an annual increase of 3% in the number of flights. It is expected to reach 11.2 million by 2019 in the 28 EU Member States.
By 2036, about 6 million Europeans are expected to be exposed to noise levels of at least 55 decibels day and night, according to the European Commission. This noise is comparable to the noise of a highway.
The extension of Paris-Orly airport this year (commissioning of the terminal known as Junction) and the passage in 4 years of 27 million to 33 million travellers come to increase these concerns. Noise is a recognized public health issue. So how do you manage an airport to reduce noise when airlines replace their fleet by larger aircrafts, certainly with increased capacity but much louder? Groupe ADP has put in place several measures that promote a serene coexistence between its airports and their neighbours.

Modified take-off and landing phases

Groupe ADP is focusing its work on noise reduction through changes in landing and take-off procedures to help aircrafts spend less time flying at lower altitudes. A directive from the DGAC aims to increase the initial altitude to 5000 feet and then, once this altitude has been reached, to encourage pilots to continue up to 10,000 feet. This procedure has already been set up in Basel-Mulhouse but also in Los Angeles, New York or Tokyo with great success.

Sound proofing assistance for local residents

Another measure put in place: a system managed by the Groupe ADP, and financed by the air noise pollution tax (TNSA) paid by the airlines, makes it possible to carry out acoustic diagnostics as well as the soundproofing of their housing near the airport area. In 2018, 860 housing units benefited from this aid worth € 6.4 million compared to € 7.6 million in 2017 for minus170 homes. Limeil, followed by Villeneuve-Saint-Georges and Boissy, arrive at the top of the cities of the department where help is the most requested. 

Considerable technological improvements

Today's engines are on average 75% quieter than those produced at the birth of jet engine aircrafts thanks to constant improvements in technology and aero dynamism that have reduced the nuisances.
Lighter composite metals have increased aircraft's flexibility and wind resistance, making them quieter in flight. The reactors themselves are more refined, resulting in a reduction in noise and greater energy efficiency.
Actions coupled with technological progress, which have never ceased to improve thanks to the involvement of key industry players in innovation, therefore allowing airport infrastructures and their nearby residents to live together and make cohabitation easy. Many of these approaches are already well under way, who sole purposes are to improve the people's health and quality of life.
