A peel turns tiny releases into one loud rip
A hook-and-loop fastener does not come apart in a single motion. As you peel the strips apart, hooks bend against loops until they slip free. Each release is small, but many happen in quick succession, producing a rapid series of vibrations that blend into the familiar ripping sound.
Why pulling it apart sharply sounds louder
Peeling concentrates the separation along a moving edge: hooks release one after another as that edge travels across the fastener. A quick pull makes releases happen faster and can set the flexible strips vibrating more strongly. Those vibrations push on the surrounding air, creating the sound you hear.
Pulling slowly tends to make the separation quieter because the releases are spread out and the strips vibrate less abruptly. So the noise is not just the hooks coming loose; it is also the speed and force of the peel turning countless tiny motions into a sharp burst of sound.
