Indian police officers tackle noise pollution

The new development will primarily affect Indian motorists. 

As the second most populated country in the world, India has some serious issues with traffic. When a large number of motorists gather in one place, they start expressing their feelings with their car horns. As a result, the high noise levels irritate passersby and create even greater issues on the road. 

Police officers in Mumbai have discovered an interesting method of combatting excessive use of car horns. They proposed to equip traffic lights with acoustic sensors. When noise levels surpass the 85 dB level, the green light will be deactivated, which will prevent drivers from moving forward until they calm down.

This idea has already been tested on several key intersections in the city. The experiment will be continued during the following month. If this measure of combatting noise pollution is proved to be effective, the system will be rolled out in the entire city.
