Just a question.....
Some time ago light aircraft crashed due to an engine failure. In the report the AAIB mentioned that the the four occupants were wearing ANR headsets and queried the possible masking of unusual noises by the headsets.
What are the thoughts of people with regard to the noises that are effectively suppressed by an ANR headset which might give rise to a quicker recognition of trouble brewing.
I know I have traditionally been a critic of ANR, but that's not to say I am not open minded and I am not having a dig.
