The whole idea of background sound while reading used to distract me. I'd put on classical music or lofi beats, but found my brain kept latching onto the melodies. Then I tried some 'coffee shop ambiance' from an app, and something clicked. It wasn't music, just a low hum of indistinct chatter and clinking cups. My mind stopped trying to follow a tune and just settled into the page.
Infinite flow stuff—rain on a window, a crackling fireplace, library sounds—works similarly for me. It creates a gentle, predictable sound barrier that muffles the real-world distractions like a neighbor's TV or street noise. It's not about the sounds themselves being interesting; it's the opposite. They're just boring enough to tell my brain, 'Nothing important is happening here, you can focus on the book now.' I finished 'The Silent Patient' in one sitting with a thunderstorm loop playing. The fictional storm outside my window somehow matched the book's tension without ever pulling focus.
