After reading about the CI 611 CVR initial findings I am curious as to whether CVRs pick up noise via the structure as well as air borne noise?
If they are fairly rigidly mounted to the structure this would enable them to pick up noise which is normally inaudible due to the background ambient noise ie skin creeping prior to failure.
It would also be interesting to know if the Aloha "convertible"
737 CVR recorded similiar noises as the skin failed.
Thanks in advance
