DUFENSE is the super directional speaker (1khz sine ±15’ -10dB) that drivers in vehicles running over 110km/h can clearly hear an audible message and warning. The sound can be herd in a car from max 600m while the car is running over 110km/h. The sound is enough strong to attract a driver when a car is within 200m from the installed speaker. At this moment, the driver has 8s to recognize a traffic pattern change or to avoid unexpected risks.
