  • The Bruitparif control center is exported to Toulouse where it has just deployed six new noise sensors to measure airport pollution.

  • Funded by the Region and the Department, this new device is a delight for residents.

  • Until now, they only had data from the six sensors of the Sentinel device, managed by the airport itself.

The debate on noise pollution at the very urban Toulouse-Blagnac airport has been part of the background noise of the Pink City for twenty years.

Until now, it was only supplied with technical data by the six sensors of the Sentinel network, managed by the platform itself.

"I do not want to cast suspicion on this system, but we are only given the figures that we are willing to give us, the airport is judge and party", recalls Chantal Request, president of the Collective against air pollution of the Toulouse metropolitan area (CCNAT).

To discuss "cohabitation", the noise slayer will soon be able to put an end to this "anomaly" and put on the table other objective data, other decibel curves.

Those of the six sensors deployed on December 18, in Daux, Aussonne, Ramonville, Croix-de-Pierre, or on the side of Jean-Jaurès University and Purpan University Hospital.

An "independent" device, financed by the regional council and the departmental council, and entrusted to Bruitparif, an autonomous assessment center whose seriousness is recognized.

"It was a plane, I'm not crazy"

The data from the new Toulouse sensors are already available, in open source and in real time, on a platform.

So of course, you have to be a long-time noise activist or a particularly traumatized local resident, to master the Autan wind too, to understand the finesse of the data, to sort it out.

"People will get used to and understand little by little and we will try to publish an explanatory video, but first the platform allows us to verify, to say 'it was indeed a plane, I am not crazy'" , underlines Jérôme Favrel, engineer of the CCNAAT.

Passages and timetables are in fact easy to identify, as are their noise levels in relation to the various recommended thresholds, in particular that of the World Health Organization.

The boomerang effect of confinement

"We can already see that old, very noisy Boeings fly at night," notes Chantal Ask.

It also notes that the relative calm caused by the health crisis in the Toulouse sky is a good period for breaking in and adjusting the Bruitparif sensors.

Moreover, the forced apathy of air transport has not reduced the number of complaints from residents.

"They got so used to silence during the first confinement that, for some, the slightest passage becomes unbearable," explains the president of the CCNAT.
