Blankets make a rustling sound when you move them because of the way their fabric rubs together. Imagine wearing a sweater and moving your arms, it makes that soft shush-shush noise, right? That’s kind of like what happens with blankets: the fibers in the fabric slide over each other, creating tiny vibrations in the air, which we hear as rustling. The more layers or texture there are on the blanket, the louder and more interesting the sound can be.
Examples
- When you shake your blanket to get rid of wrinkles, it makes that shush-shush noise.
- Putting a soft blanket over your head feels like it's whispering to you as it moves.
- Your pet dog might be making the same kind of rustling sound when they snuggle into their bed.
