Patent ID: 8606547

Claim:
A method for measuring the aerodynamic noise of a vehicle, the method comprising: arranging the vehicle in a measuring station provided with a supporting element which carries at least one blower adapted to generate an air jet towards the vehicle; generating the air jet towards the vehicle by means of the blower carried by the supporting element; displacing, by means of an actuating device, the supporting element with respect to the vehicle from an initial position to a final position; measuring, by means of at least one phonometer, the aerodynamic noise produced by the vehicle struck by the air jet generated by the blower; communicating the measurements of the aerodynamic noise to a processing unit; detecting, with a position sensor the position of the supporting element with respect to the vehicle; communicating the measurements of the position to the processing unit; correlating, with the processing unit, the aerodynamic noise measurements supplied by the phonometer with the position of the supporting element with respect to the vehicle so that each aerodynamic noise measurement is associated to the position of the supporting element with respect to the vehicle at the time when the aerodynamic noise itself was measured; setting a maximum aerodynamic noise acceptability threshold for validating the vehicle and a minimum aerodynamic noise acceptability threshold for validating the correct operation of the system for measuring the aerodynamic noise; comparing the aerodynamic noise measurements supplied by the phonometer with the acceptability thresholds; and indicating as anomalies in the vehicle all of the aerodynamic noise measurements which exceed the maximum acceptability threshold and indicating as anomalies in the system for measuring the aerodynamic noise all of the aerodynamic noise measurements which are below the minimum acceptability threshold.
