DC claims additional 17-22dB noise attenuation with ENC turned on;
regular foam earplugs are said to do around 32dB of attenuation. Seems
even better than ENC, and hell of a lot cheaper, too... Does anybody
have any opinion on that?

Query: I haven't flown a light plane since 1981, so I've never had
the occasion to use ANR. When in use in a typical light single like
a 172, etc., can you hear the engine, or the airflow, or even your
passenger speaking (without benefit of an intercom)?

I can hear the crinkle of un/folding my charts while in flight. I've also
heard fingers snapping.
