I had ment to post this earlier, but this YouTube channel is a gentleman that is blind from birth and he essentially talks about his experiences, but also has a open forum where people can submit honest questions about what it is like to lack a sense from birth. He does a really good job of describing his experiences, and even though he is blind not deaf I think that the way he processes things and how his brain is wired might be valuable insight
In particular there is an episode where someone asks him to draw a cat. The result will surprise you. It worth a watch.
This particular video from his channel is also very interesting and might be useful
