It's strange but I feel like with audiobooks the information is transferred directly into my mind. With reading text I have to convert the text into words in my mind so it can then be understood. This is a nearly instant process and almost imperceptible, but it does make listening to an audiobook an easier form of reading with a higher level of comprehension for me. I can get the same from a paper book, but it takes a little bit more mental work to achieve the same level of comprehension.
Perhaps some people can look at a word and have it directly understood without thinking about how the word sounds. I probably can do that just fine for individual words, but when it comes to painting a complex scene in my head it just doesn't work without a bit more effort.
It's unfortunate because I have a misophonia problem and sounds, especially the sounds of peoples voices annoys me greatly. It's completely out of my control. I just hear specific sounds and I can feel my body getting anxious. Some voices cause this problem and others don't. I have no idea what about someones voice annoys me, but it is a completely involuntary reaction no amount of logical reasoning can get rid of.
