the passive ones for about 10 years. Just replaced the padding and mic

Thanks Travis,
Your comments on the passive headsets are interesting, I've noted that the
Avweb article on LightSPEED talks about the QFR series being great value
for
a passive headset.

I hope that you did not take my passing comment about having passive
headsets as a point in a direction other than ANR. Do not, and I repeat, DO
NOT buy passive headsets for yourself as the pilot. I bought passive
headsets a long time ago and I will never buy another pair.

I have ANR for myself and my frequent co-pilot - both sigtronics S-AR. I
have two passive headsets (also sigtronics) that I use for the backseat
passengers only because that is a fairly infrequent event. I would have ANR
headsets for as many people as you regularly go flying with.

As my headsets fail (if they ever do!), I will replace them with a
reasonably priced ANR set and sequence them in the plane as appropriate. In
other words, I will buy the best damn pair of ANR that I can afford and it
will become mine, mine, MINE, ALL MINE, I tell you!

Thanks Travis, I think I get your point :-)

I own a Piper ArcherII PA28-181.
In all the years I have flown this aircraft I haven't used a headset, mainly
because when I have tried it I find it strange not hearing the same engine
sound I have always been used to.

Hi Steve,

I hope you are using some kind of ear protection, if not a headset. This
is a great hobby, but it's not worth losing your hearing.

The Archer isn't all that loud. I can carry on a conversation in a
normal speaking volume in my Archer while in cruise. Apart from that,
the low frequency noise poses much less of a short-term risk for
noise-induced hearing loss.

That being said, I use a headset in my airplane, and can't imagine
flying for very long without one, especially when radio work is required.

While ANR headsets may be the way to go, it is important to understand
that there is _NO_ clinical evidence that ANR does anything to preserve
a person's hearing over passive attenuation.

Jonathan,

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

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.
