Quite. Look at their hapless T&T straps department. Just hopeless. Around 30 years working on the problem and no solution. I thought us Americans were supposed to be great engineers. The identical part number is OK to fly "on condition" on Kiowas but just 2 years on civilian machines. Love flying the 412's but it must surely be the most efficient converter of JetA-1 to noise in its weight category. There are straighforward engineering considerations that can be done to reduce noise.
Maybe Bell is like the Harley of the rotary world. Lovable and iconic but no point comparing it to Jap, Italian or British bikes.
