Quiet? realtively
Silent? no
Think about it, most commercial helicopters use gas turbine engines which by the nature of the way they work, can't be silenced without reducing the efficiency of the engines. Then theres the rotor system its like a huge fan. Theres no way of silencing this.
Helicopters are really only audible at close ranges of about half a mile away. Beyond this, they are unnoticeable. I live next to a search and rescue helicopter base, and they really don't make much noise at all.
