If you have some sort of echantment granting you protectection from falling (Protection IV +Feather falling on boots works well) and you fall from a height that if you did not have the echantments would cause fall damage (not counting landing in water - but it might play there and get lost in the splash sound...), you do not take the damage but the sound of hitting the ground hard and the camera jerk animation plays.
Expected: No damage?, Then No sound or camera jerk.

This is working as intended per MC-161149.
sometimes if you take less than 1 point of damage (but still enough to cause you to take damage) the damage animation and sound will still play. take, for example, a zombie punching you while you are in protection 4 netherite armor. you don't take any visible damage to the health bar, but you still take some damage.
