70 percent of Brussels residents become aviation because of too much traffic noise. The Brussels Region is therefore going to test three types of noise radars. A new study also finds that the zone 30 makes the city much quieter. Striking: modern cars still as loud as old models.
Traffic noise is an often recognized problem in cities. In the Brussels region, 70 percent of the population is thus reached at a noise threshold that is higher than the standard of the World Health Organization (53dB).
Brussels Environment therefore launched a measurement campaign on passing cars in 2020, which aims to better map the problem. The study shows that it is mainly the speed of indications how loud they are. Where the speed is brought from 50 to 30 km/h, the sound volume is immediately brought too.
For environment minister Alain Maron (Ecolo), this result shows that the generalized zone 30 is not only efficient for road safety, but also ensures a calmer and more planned city.
Below a speed of 30 km/h, the measurements show. The activities activities that it also remains important to turn on driver style.
One vehicle is not like another, the study shows. Motorcycles and trucks in particular are a lot louder than passenger cars. One motorcycle makes noise like 2.5 passenger cars. Vans are also somewhat louder than passenger cars. Remarkable: electric cars are not really quieter than cars with a combustion engine. The researchers do not yet have a unequivocal explanation for this phenomenon.
Another clear argument: new cars are not quieter than old ones. “You have seen an improvement in the emission of polluting substances over the years, but there is no such thing as noise, which surprised us,” says Benoit Fauville of Brussels Environment.
Maron says that the Region is now going to test three different types of sound radars. The devices must provide a better view of situations and vehicles that cause too much noise. The purpose of the radars is therefore primarily scientific. If the radars are useful, the Region can purchase more.
In France, the same types of radar are being tested today to fine vehicles that are too loud. A law was recently passed in the southern neighbors that makes such fines possible. Since it concerns the same technology in Brussels, it is also technically possible in Brussels. There are no concrete plans for a more framework yet.
