Jonathan,

The Archer isn't all that loud.


It's ok that you like your plane, but that's just, uhm, ridiculous.


I didn't comment on whether I do or do not like my airplane.

The layman's litmus test for whether ambient noise may be damaging is
whether or not you can carry on a normal conversation without raising
your voice to do so. If you can, the ambient noise level is no more
damaging than the normal speaking voice. I suspect that many folks play
their automobile radios at a higher volume than that required to carry
on a conversation in an Archer during cruise. In my particular case, my
airplane was equipped with the "super soundproofing," so such insulation
and thicker windshield undoubtedly contribute to reducing the noise
level in my airplane.

Thomas, you seem to be a perpetual presence in every thread having to do
with headsets or hearing protection while flying. Not only do you
appear to have some undisclosed personal interest in promoting
LIghtSpeed headsets, but you continue to lead folks to believe that ANR
headsets somehow contribute to "preserving" their hearing over passive
attenuation sets. Yet, you have never cited any data to support your
claim. You are not alone. I have never witnessed anyone else cite any
applicable, peer-reviewed, clinical studies that show any benefit to ANR
for hearing protection.

There may be a benefit to ANR for comfort, or for fatigue, etc, but all
of those evaluations are quite subjective. There's a big difference
between an opinion on comfort and using fear of permanent hearing loss
to promote a product.

Jonathan,

Thomas, you seem to be a perpetual presence in every thread having to do
with headsets or hearing protection while flying.

Yep. I'm simply interested in the topic.

Not only do you
appear to have some undisclosed personal interest in promoting
LIghtSpeed headsets,

Nope. I simply like mine. I also like what the company brought to the
market - innovation at a low price. That's a fact I'd like to see disputed.
My wife has a pilot shop selling several brands of headsets. Lightspeeds
are currently not sold in Germany. They were, though.

but you continue to lead folks to believe that ANR
headsets somehow contribute to "preserving" their hearing over passive
attenuation sets.

Nope. I just point to the facts as known, including the well known and
supported fact that ANR for many frequencies will lower the audio pressure
a microphone positioned at the point where your ear would be while wearing
the headset is subjected to. Whether or not that preserves your hearing I
have not said. You may quote any statement you have seen me make saying
anything remotely like you claim above.

I have never witnessed anyone else cite any
applicable, peer-reviewed, clinical studies that show any benefit to ANR
for hearing protection.

So what? I have not seen you cite evidence to the contrary.

What I have seen is your being a perpetual presence in every thread having
to do with headsets or hearing protection while flying. You appear to have
some undisclosed axe to grind against ANR. You continue to lead folks to
believe that ANR headsets somehow do NOT contribute to lowering noise for
the wearer of the headset.

Thomas,

I need to be more precise:

My wife has a pilot shop selling several brands of headsets.

That shop is in Germany.

Lightspeeds
are currently not sold in Germany.

And that would exclude the Mach 1, which is sold here.
