Just a word or two of caution, folks. Sound levels in SEL airplanes
can exceed 90 dB A at the pilot's ear, and prolonged exposure to that

worth of electronics in each ear now, partly because I didn't use a
headset in the airplane in my younger days (lots of gun fire and some
evidence of family hearing loss are also factors). Even if you're not
using the radio, protect your hearing.

clear.

Well, for me, make that C L E A R!

(Can you hear me now?)

Huh?

My wife use to work for an ENT for years and would tell of the train
personal that don't wear hearing protection and have severe hearing
loss. I see the fire truck personnel now have DC headsets. I ought to
equip my car with ANR headsets. Notice how bad road noise is now even in
good cars.

Unfortunately, while a Good Idea(tm) it may not be practical due to
the motor vehicle laws - in Minnesota, it is illegal to have
headphones in both ears while driving. It is my understanding that it
is so that the driver is not isolated from the outside world (horns
honking, sirens, general distraction) - I am sure the law came about
before active noise cancellation headphones, though as those could
actually enhance the driver's ability to hear such things.
