sound levels and hearing loss

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
level can lead to hearing loss. I stuff a couple of thousand bucks
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?)

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.

Cite:
Minnesota Statutes 2006
169.471 TELEVISION; HEADPHONES.

Subdivision 1. [snipped - pertains to television]

Subd. 2. Use of headphones in vehicle. (a) No person, while operating
a motor vehicle, shall
wear headphones or earphones that are used in both ears simultaneously
for purposes of receiving
or listening to broadcasts or reproductions from radios, tape decks,
or other sound-producing or
transmitting devices.
(b) Paragraph (a) does not prohibit:
(1) the use of a hearing aid device by a person who needs the device;
or
(2) the use of a communication headset by a firefighter while
operating a fire department
emergency vehicle in response to an emergency.

...for purposes of receiving
or listening to broadcasts or reproductions from radios, tape decks,
or other sound-producing or
transmitting devices.

That's a key section. If you wear a noise cancelling headset which
covers both ears, but not for the purpose of listending to radio (etc),
then you're ok by that law.

I took a Radio Shack sound meter aloft with me one day. 109 dB at chest level.

I wear an ANR, now....

Lower levels can also damage hearing over long periods. From what I've seen
of measured sound levels in GA aircraft (and some larger aircraft), many
pilots are risking significant hearing loss over the long term unless they
wear effective protection against cockpit noise.

In small aircraft, passengers should also wear ear protection.

Mow here's a thought -- under MN law, is an airplane a 'motor
vechicle'? Maybe even if it is, runways are not highways and the state
police do not patrol them so you can get away with your DCs. Now, some
states (for personal safety reasons I am not listing my candidate
states) very will might have a cop with a radar gun along a runway.
Touch down hot and get a ticket (that of course would be a good idea
anyhow). Get another one for wearing a headset.

I think it's time for my meds.

What is the posted speed limit on the runway?
