ABSTRACT:
The present invention provides a method for evaluating the presence and performance of a vehicle's audio system drivers without the need for having to manually or remotely control the audio system parameters during the testing period. After establishing baseline characteristics for a driver group to be evaluated, a predetermined broadcast signal is used to excite a particular subgroup of drivers within the driver group. The output from the subgroup of driver drivers is detected by microphones strategically disposed within the vehicle amongst the group of drivers. The detected output from the driver drivers is thereafter decoded and analyzed with respect to the baseline performance to determine if the drivers are performing within expected specifications.
