I agree with Joe, remove the flex duct and install hard duct. You may
also want to install a speed control for the motor, why have this fan
running at maximun RPM when you are just boiling water, or frying eggs.
Why are you complaining? I thought everyone wants an industrial grade -
super duper, "commercial cooking" set up in their home. Enjoy the
sounds of a commercial kitchen, since in your case you can reduce the
sound of moving air a little BUT it will never be what you were used to
on your "basic no-frills" kitchen hood.
