Question Most survivors couldn't hear or feel the collision with iceberg. Why is that?

I've read a few accounts, and each one of them stated that there was "no sound" or "just a light sound". Honestly, I'm confused. Why would the ripping of the hull by massive knives of ice not be heard or felt?
The damage to the ship happened on the lowest possible level. First class and second class were higher that third class that probably heard the impact and went onto the poop deck.
