I’m vacuuming right now and I just bend down on my knees and I hear a crack. Didn’t feel like a bone crack, but more like maybe I put pressure down on a ligament or something? But it didn’t hurt?
How can it be so loud sometimes when it’s incased in liquids & barriers and such of the human body?
In: Biology
Nearly all of your bones are open to the air, not hidden behind some barriers. Your bones *are* the barriers. So when a joint between two bones creates a sound, it’s basically as open to the air as your fingers are when you snap.
A lot of the sounds your body makes are mechanically very similar to snapping your fingers as well.
