My son, who flies helicopters for the Coast Guard, called me last night and told me that they "immediately" told
them they would not be allowed to use ANR headsets. Said that a study has been done and ANR's have been
shown to cause irreversible hearing damage. I have not heard anything about this at all.
He was concerned enough about it to tell me to stop using my Lightspeeds. I find this hard to believe,
but he was adament. Anybody else hear anything?

Dave:

This information is over a decade out of date, so take that into consideration.
However, when the Canadian air force evaluated ANR headsets in the early 90s
they found that the systems available, which were designed for fixed-wing
aircraft, were not suitable for helicopter crews due to the very different
frequency distribution of helicopter noise. It's possible that the information
your son was given is valid for turbine-powered choppers but not for
piston-powered airplanes.

This is an almost verbatim quote as it appeared on the Cessna Pilot's association website a year ago??????????????????????????

Must be some brand new safety officer at a new duty station dusting off some old info
