An automatic wiper control system for a vehicle window determines the presence of rainfall based on window vibrations. During a vehicle driving cycle, a controller measures the window vibrations with an accelerometer attached to the window. The controller calculates a psycho-acoustic metric based on the measured vibrations, wherein the metric can be comprised of Articulation Index, Sharpness, or Roughness. The calculated metric is compared to a threshold indicative of rain impacting the window. The wiper system is activated according to a result of the comparison.
