How long does it take to listen to an audiobook?

Audiobook listening time depends on the book's length and playback speed. A 10-hour book takes 10 hours at normal speed, 8 hours at 1.25x speed, or 6.7 hours at 1.5x speed.

What is the best speed for listening to audiobooks?

Most listeners find 1.25x to 1.5x optimal for fiction and 1.0x to 1.25x for non-fiction. Start at normal speed and gradually increase based on comfort and comprehension.

Does listening to audiobooks at faster speeds affect comprehension?

Speeds up to 1.5x typically maintain 90-95% comprehension for most listeners. Speeds above 2.0x may reduce retention significantly, varying by individual and content type.

How can I calculate my audiobook completion time?

Divide the book's duration by your playback speed, then add break time. For example: 12 hours ÷ 1.5x speed = 8 hours + breaks.

How much time can I save by increasing audiobook speed?

At 1.25x speed, save 20% time. At 1.5x speed, save 33% time. At 2.0x speed, save 50% time. However, consider comprehension impact at higher speeds.

What factors should I consider when choosing audiobook speed?

Consider content complexity, narrator clarity, listening environment, personal comprehension rate, and purpose (entertainment vs. learning). Adjust speed accordingly.
