I've nothing against audiobooks, but for me the experience is so different as to constitute a different thing, especially when it comes to fiction.
Firstly, an audiobook moves through the text in a straightforward linear way, but with a printed text I think a lot of readers tend to do things like:
Do an initial skim-read of a page before reading the page more slowly,
Linger and re-read striking sentences,
Read less interesting parts more quickly
Move back to an earlier paragraph, or even an earlier chapter, and re-read it in the context of the new information found in a later paragraph,
underline things and write things in the margins.
Personally, I feel like the visual appearance of the printed letters in a character's name plays a part in how I imagine them, though maybe something analogous happens there with the way a name sounds in an audiobook.
