Literary sociologist Karl Berglund, together with pharmacologist Christian Benedict, will investigate how Swedes use audiobooks to fall asleep.
"We want to find out what these practices look like in more detail and how audiobooks relate to other forms of sound, and how people experience that listening to audiobooks affects their sleep," Berglund writes to Svensk Bokhandel.
Data collection is carried out via a survey for adults over the age of 18 who have ever used audiobooks in relation to sleep.
