Steps to Reproduce:

1. Place a Sculk Sensor on the ground;
2. Use a comparator to get the correct vibration type;
3. Place a line of redstone dust to observe the signal strength;
4. Place any slab or sea turtle egg nearby;
5. Add another slab/egg on top of the already placed one.

Observed Results:
The vibration of the added block produces a level 6 "Block Change" signal.

Expected Results:
The vibration produces a level 12 "Block Place" signal.

Notes:
