After years of flying the Gazelle and moaning about the noise of the fenEStron, I was gobsmacked in the early 2000's when the Cornwall Air Ambulance 135 landed near our hangar at St Mawgan - it was so quiet by comparison!
So if they have made it quieter still then well done Airbus.
Interesting too that the Puma, at 7 tons was deemed to big for early fenEStron tech yet now the H160 at (I think) 6 tons is suitable so the performance/efficiency increase has been marked as well.
