After the Huey....how can anyone describe a helicopter as being "noisey"!
I loved flying the Huey....despite some its shortcomings...it was and still is...a wonderful machiine especially for its time. Its younger sibling....the 212 is also a great machine...but noisy.
The Chinook, 53, and other big machines are "noisy" but then so is the Osprey in certain aspects. When you get to moving all sorts of air around by means of Rotors Blades and Prop Rotors....there is going to be noise created....and until someone figures out an easy way to quieten Tail Rotors and Turbine engines...."noise" is a relative concept when comparing the various aircraft.
