If you want to get scientific about it, one could argue that the sense of sight has four cranial nerves devoted to it, whereas the sense of hearing has only 1. While it's true that only one of the four craninal nerves devoted to vision actually transmits visual information to the occipital lobe of the brain, (the others innervate the small muscles of the eye) vision is arguably the most important sense. Does all this really matter? Not really becuase it all boils down to the emotional experience.
