Can the volume of the car horn be controlled? BMW applied for patent of adaptive horn.

When I was a child, I liked to imitate the sound of the car horn "Didi" and "Dad" for fun. Nowadays, in a busy adult world, noisy horns are easily offensive, and some people even quarrel in the street because of honking their horns. I believe many people have encountered such a thing, which is very annoying. Recently, we got news from China National Intellectual Property Administration that BMW applied for a patent of adaptive speaker volume control, which can effectively reduce noise pollution sources. As we know, in many cities all over the country, there are sections where horns are forbidden, in order to reduce the impact of noise pollution on surrounding residents and units.

BMW's adaptive horn volume control system can dynamically control the horn volume according to the driving environment of the vehicle. For example, when driving at 120km/h on an expressway that does not affect pedestrians, the volume of the driver's horn will increase. When driving at 15km/h in cities or internal roads, the volume of the driver's horn will decrease.

It is reported that BMW's adaptive horn volume control system can also be integrated into the automobile system. We guess this may mean that the system can link high-precision maps and road traffic identification functions, and * * * can enjoy the active identification of road signs and online data of maps in other systems, thus achieving real intelligent adaptive speaker volume control ability, not simple speed control.

Of course, whether we can do all this will be determined after mass production and when BMW finally officially announces the functions of this system.
