Raindrops against leaves, pages turning, or a soft tap(轻敲) on wood—if you search for “sleep-aid audio（助眠音频）” online, you’ll find many quiet and creative sounds. Made by hand, created by AI, or recorded from nature, they help listeners fall asleep more easily. Thus, these videos have become popular among young people in recent years.
Yan, known as @1649 C, is a sleep-aid video creator. She has been creating sleep-aid works for more than three years and has over one million fans online. Although she makes videos, Yan mainly focuses on audio materials. “The sound of wood brings a natural sense of calm and warmth. Because of that, wooden objects—like blocks, spoons, and bowls—have become some of my favourite sound materials,” she said.
The fun of making such vlogs is similar to being a musician, according to Yan. “Many sleep-aid vloggers have developed a habit of tapping on everything they can see,” she laughed. “It’s like looking for every possible ‘instrument’ to make the exact sound you want.”
Yan only records at midnight. “There are too many
interruptions in the daytime,” she said. “Even the sound of footsteps from upstairs would be too loud.” She herself also has to be completely relaxed. “You have to be calm to create a calm sound,” she said. The quiet midnight environment lets her capture pure and gentle sounds.
Many of her fans watch her videos at night before going to bed. “Some of them face pressure from school or work. My videos are what they turn to at night. The sounds offer them comfort, like a friend is there,” said Yan. “I’m glad that my videos can make a difference.”
