ARE PRESENT HORNS, WHISTLES AND SIRENS NECESSARY FOR COMMUNICATIONS?

VARIOUS TYPES OF EXISTING AUDIBLE WARNING SYSTEMS AND THEIR HISTORICAL DEVELOPMENT ARE DISCUSSED IN THIS PAPER, TOGETHER WITH AN ANALYSIS OF THEIR EFFECTIVENESS IN FULFILLING THEIR PRIME FUNCTION - NAMELY, TO WARN PEOPLE OF IMMINENT DANGER. IT IS CONCLUDED THAT SUCH SYSTEMS PERFORM ADEQUATELY IN MANY SITUATIONS, BUT NOT WHEN THE RECIPIENT OF THE WARNING SIGNAL IS INSIDE ANOTHER VEHICLE. IT IS SUGGESTED THAT ALTERNATIVE MEANS BE DEVELOPED FOR WARNING THE OCCUPANTS OF VEHICLES OF IMMEDIATE DANGER SO THAT AUDIBLE WARNING SYSTEMS OF REDUCED ACOUSTIC POWER CAN BE USED TO WARN PEDESTRIANS OR OTHER PERSONS OUTSIDE VEHICLES. /DOT/
