It's an interesting thought, Zeez. But maybe I can persuade you that the most important aspect of sensory input is perception rather than the act of receiving the data itself?
Let's take sight. As a child, many of us were probably taught about the mechanics of the eye and how the lense of the eye first takes the image which is actual upside down but then this upside-down image is reprojected as right-side up when viewed by the mind. Yet what would we really mean by the idea the mind is viewing the image seen using the eyes? That there is a little man in our heads "watching" the movie captured by our eyes? Then how does the mind perceive the data without having a similar problem? At some point, the data has to become something other than mere object - it has to be converted to something that can be internalized - perceived.
If you watch the video I linked to for Quasimodo, Ramachandran actually does a very good job explaining this, using the example of optical illusions. For example, he shows us a skeleton drawing of a cube and then asks how many people can make the image project outward, inward, up, down, depending on how they choose to perceive it? This wouldn't be possible if there wasn't some interaction with the raw data by the brain, creating mind. He shows other famous illusions such as the young lady/old lady painting, below, and asks if the operation doesn't involve the mind why can many of us see both images, though some of us may need it pointed out to us?

I think the same can be said for sounds. Have you ever had a strange sound startle you and you swear it was a dog bark or growl, only to hear it again and realize it was something else entirely? I think this is our evolutionary roots showing - the brain that quickly identified a threat and acted to remove itself from the threat survived while those who failed to do so didn't. So we have this vestigial tendancy to quickly interpret input as something threatening. I think this plays into haunted house phenomena for example.
Anyway, what do you think? Is perception so critical to the senses that to separate it would be to do damage to the discussion? Or am I forgetting something?
