When falling and taking damage on wool, you produce vibrations which are detected by sculk sensors. In 1.19 this didn't seem to be the case.

Steps to reproduce

1. Load world in 1.19.2
2. Place wool down
3. Place sensor near the wool. Make sure they aren't on the same height so the sensor isn't occluded by the wool
4. Switch to survival mode and fall 4+ blocks on the wool
5. Notice you don't set off the sensor
6. Load the world up in 1.20.1
7. Fall on the same spot
8. Notice you do set of the sensor
