Eight cities in France, including Paris, will install devices that detect the decibels produced by vehicles during circulation and will fine those who exceed the limit, with the aim of reducing noise pollution.
These sound radars were officially baptized as “Jellyfish” by the similarity in its form with the marine animal. Are composed of four microphones and a 360-degree camera which photographs the infringing vehicle’s patent, whenever it detects it.
Jellyfish are prepared to detect loud noises, assign them to a particular direction, and establish their origin, and then take a photo.
The system it was already tested during June on a circuit in Nantes. Due to the good results, the French authorities decided to make use of this technology and will gradually install it in towns such as Nice, Toulouse and Paris.
According to the National Noise Council and the French Ecological Transition Agency, they estimated that the annual cost of noise in terms of health and economy reaches the 156 billion euros.
The specialists assure that the sound begins to be harmful to people’s health from 75 decibels
and painful from 120, although from 55 it can become dangerous. And that is precisely the limit (55 db) that the cars will not be able to exceed.
Those drivers whose vehicles cross the 55 decibel barrier must pay a fine of between 60 and 60,000 euros, according to the seriousness of the offense.
Based on a study published in the British Medical Journal (BMJ), being exposed to traffic noise from vehicles and trains is related to a higher risk of dementia, especially the disease of Alzheimer, one that causes problems with memory, thinking and behaviors.
Paris lowered the speed limit
In order to reduce noise and environmental pollution, as well as to reduce traffic accidents with fatalities, Paris also lowered the maximum speed limit on urban streets at 30 km / h and on avenues at 50 km / h.
According to the polls, the majority of the citizens of Paris agree with the lowering of the limit from 40 to 30 km / h on urban streets, although the decision also found detractors. Among them, taxi drivers, who adthey pour a considerable increase in the fare as a consequence of – it is assumed – the rise in travel times. In any case, a survey found that the average speed in the center of the French capital is 11 km / h.
Since lowering the maximum speed limit appears to be a global trend, the ANSV recommended that governments implement it in Argentina.
