Although I listen to a lot of podcasts (here’s my OPML file) I don’t listen to many audiobooks. That’s partly because I never feel up-to-date with my podcast listening, but also because I often read before going to sleep. It’s much more difficult to find your place again if you drift off while listening than while reading!

This article in TIME magazine (is it still a ‘magazine’?) looks at the research into whether listening to an audiobook is like reading using your eyes. Well, first off, it would seem that there’s no difference in recall of facts given a non-fiction text:

For a 2016 study, Rogowsky put her assumptions to the test. One group in her study listened to sections of Unbroken, a nonfiction book about World War II by Laura Hillenbrand, while a second group read the same parts on an e-reader. She included a third group that both read and listened at the same time. Afterward, everyone took a quiz designed to measure how well they had absorbed the material. “We found no significant differences in comprehension between reading, listening, or reading and listening simultaneously,” Rogowsky says.
However, the difficulty here is that there's already an observed discrepancy in recall between dead-tree books and e-books. So perhaps audiobooks are as good as e-books, but both aren't as good as printed matter?

There’s a really interesting point made in the article about how dead-tree books allow for a slight ‘rest’ while you’re reading:

If you’re reading, it’s pretty easy to go back and find the point at which you zoned out. It’s not so easy if you’re listening to a recording, Daniel says. Especially if you’re grappling with a complicated text, the ability to quickly backtrack and re-examine the material may aid learning, and this is likely easier to do while reading than while listening. “Turning the page of a book also gives you a slight break,” he says. This brief pause may create space for your brain to store or savor the information you’re absorbing.
This reminds me of an article on Lifehacker a few years ago that quoted a YouTuber who swears by reading a book while also listening to it:
First of all, it combines two senses…so you end up with really good comprehension while being really efficient at the same time. ...Another possibly even more important benefit is…it keeps you going. So you’re not going back and rereading things, you’re not taking all kinds of unnecessary breaks and pauses, your eyes aren’t running around all the time, and you’re not getting distracted every two minutes.
Since switching to an open source e-reader, I'm no longer using the Amazon Kindle ecosystem so much these days. If I were, I'd be experimenting with their WhisperSync technology that allows you to either pick up where you left up with one medium — or, indeed, use both at the same time.
