Horns and Acoustic Devices New Technologiesfor Urban Traffic Noise Disturbance Reduction

Usual electromechanical horn technology doesn't allow any horn noise control and leaves disturbance vs. safety management to the civic sensibility of the drivers.

Electronics, loudspeaker technology, multiplexing and psychoacoustics give the car designers as well as the public authorities new tools to control unnecessary horn noise without loosing safety or increasing costs.

These technical solutions are already available, sometimes even applied for other purposes and don't require any major vehicle modification or cost increase.

Furthermore, they can give car designers new sounding options and “Brand Management” opportunities without any public disturbance increase.
