China to Stop Excessive Car Honking with Acoustic Cameras

car horn detection cameras china

Who doesn’t hate excessive honking, the noise practically embedded into the fabric of urban life? That is why China is taking drastic steps to reduce car honking, the first being… acoustic cameras.

Police officers in forty cities will analyze a two-second movie of a honking car to determine if the drivers in question had a reason to lean on the horn in the first place. If not, they’ll get a fine.

“The acoustic camera system consists of a 32-microphone array, a high-definition camera, a display screen, a flash and a processing system.

Once a car honks, the microphones zero in on the source of the sound. The camera will then capture the image of the car’s license plate and film a two-second video,” explains Inkstone News.

This project aims to reduce the area’s increasing noise pollution. At the moment, Beijing is in top six noisiest cities in the world.

With that in mind, forty Chinese cities have installed acoustic cameras capable of catching honking drivers with an accuracy rate of 92% to 95%.

If they get combined with facial recognition like these police officers use and rolled into the dystopian social credit system, things are going to get interesting over there (though definitely quieter!).

However, at the moment, the acoustic cameras are not capable of identifying drivers on the spot. They still rely on human officers reviewing the footage.
