That does work really well, did that a few years ago with an old Comtronics headset
and it did make a huge difference. You have 2 sound barriers instead of
1. Guess I got lucky, did it just like the guy in the video, it was very simple
and easy to do.
The Comtronics died of old age, am currently using a Gulf Coast Avionics noise
canceling headset, and it is doing a good job - wonder what would happen if you
attached the earbud speakers to the GCA headset speakers w/ their noise canceling
function? Better? Worse?

You got me browsing for magnetic connectors and found a web page for people who
go to cosplay events and make their own clothing with lights embedded (?!? whatever)
- it uses magnets with wires attached to them for connectors. The author
talks about embedding the magnets in acrylic. I am thinking it would be easier
to just pot them in epoxy or silicone? Maybe right on the outside of the headset,
and the wires from the earbuds potted so that the magnets on headset/wire
would attract each other and keep the polarity? Scroll down the page about

No pictures, removed it years ago, passengers kept trying to get their seat belts
hung up over their throttle, so I removed the potential, but here's the basic
principle: you use a pull/pull cable system. Advancing the pilot side throttle
pulls the passenger side throttle lever open, while also pulling the carburetor
cable slide up, and when you retard the throttle, it also pulls the passenger
side throttle closed and lets the carburetor cable slide down. You do that
by making the cable attach points and pivots 180 degrees out at the same pivot
and attach lengths for the two different throttle levers. Crude drawing attached,
the big loop is the cable inside the secured cable sheaths. You'll get
the idea.
You will need cable sheath attach points on your fuselage structure to anchor the
cable sheaths into, and also cable adjusters in each half of the loop to get
things adjusted. You will want the system to have no slop, yet not bind. It's
not hard, but the devil is in the details of trying to get it to work smooth.
I still had the old parts out in the hangar, it is not possible to assemble them
to show the system, but here is some of the hardware I used.

Larry,
I fly an RV-4 using a QT Halo earplug style headset, and it is quite a
bit quieter than the old Lightspeed 15's (active noise cancelling) I
used to use. The Halo actually has the speaker elements mounted on the
headband, with small tubing connecting to the ear plugs. I would have
thought that the Clarity Aloft would be even quieter. Are you sure you
had a good seal between the ear plugs and your ear canal? If they don't
seal up completely just like regular noise blocking ear plugs, then they
won't block external sound very well at all.
I've flown with earplug style in-ear phones (Sony in-ear monitors
designed for musicians) under Lightspeed active noise cancelling
headsets, and it is a bit quieter with a noise cancelling headset on
top, but at the expense of wearing the headset. One of the things I love
about the Halo is that I don't have the weight/heat of the bulky headset
on my head.
I've never tried any type of in-ear active noise cancelling headset, but
if you could rig one with a mic, that sounds like the ultimate solution
for those of us who can tolerate 'earplugs' in our ear canals.
For those who have never used any of this stuff:
There's a huge difference between 'earbuds' like what came with your
iphone and earplug style systems like the Halo and Clarity Aloft.
Regular earbuds do not seal to the ear canal, so they don't really block
much sound at all. All regular earbuds will get you is louder sound (and
quicker hearing loss).

I just finished modifying my Sig S45 headset with a set of "ear buds".
Using a "pencil solder gun" I had no problem at all with soldering the
wires? to the speaker. Perhaps it was the type of flux core solder that I
had.
I also bought the QT Halo headset, and I liked it for the most part. I had
no problem hearing the radio, in fact I had to turn it down quite a bit,
and the best part is that I could listen to my music while flying. Not very
satisfying with a normal headset. I however was not a fan of the mic. I put
an Oregon Areo mic cover on it and it helped a lot, but the "boom for the
mic was as limp as 30 day old celery. I finally taped it to some alum wire
to give it a bit of a spine. Other wise I had to hold it in front of my
mouth if I wanted to talk to some one. My cockpit is just a cover (factory
wrap around) over the area that I sit. If I turned my head it would crack
the squelch and I would get a shot of full motor noise. So it was necessary
to turn up the squelch a lot to keep it from cracking.
You asked about seal, and I did have a good seal, but you also pick up
ambient noise through the bones that surround your ear as well. While I
could hear great, I felt that the noise of that HKS was still too loud. I
was considering using a set of ear muffs to help with the noise. To be
clear- I never had any problem with hearing the radio or my music. My wife
however often mentioned the motor noise was quite loud, and there was
occasional static. ( I think that there are better mic's out there than the
one that they use.)
I have a base station here at the house so I can talk with the wife to get
her input on clarity on her end of the conversation.
I decided to try adding the ear buds to my Sig S45's. I have found them to
be the best option for me even over ANR headsets. ( The ANR is set for GA
and works best on the 2400 RPM's of those engines. Ours turning 6000 RPM,
are out of the range that they generally work best at.)
However wearing glasses I was not happy with the noise even with gel ear
seals on the S 45's. I felt that I had to turn the sounds that I wanted to
hear up to the point that my old experienced ears would be still getting
damaging noise levels. I could not hear my music very well and if I played
it as loud as I needed to hear it at all in the plane, it would cause me to
wince at that level out of the plane.
After completing the modification I rolled the plane out for some touch and
go's. I plugged the ear buds in, covered my ears with the headset, and
found that I had to turn the volume down on both the headset and the music
radio for the first time. The noise level was substantially reduced from
both the Halo set and the S45 before modification, with the ear buds. Upon
landing my wife also confirmed that on her end the transmissions were a lot
clearer, louder and without static.
I will be using my Halo set as a backup. There was that much improvement.
Thanks Malcom.

Sounds great. Got to get me some "cheap" ear buds and go to work. I
have several DC and Sigtronic headsets to play with.
My hearing has gotten so bad and the noise level is so great in the
MKIII it takes the fun out of flying. Biggest complaint I have trying
to knock out 8 hour flight days. Noise is extremely fatiguing.
BTW: No cockpit noise comparison between a Kolb and an RV4. Kolb is
much, much louder and of a much higher frequency, engine and prop.
Pushers are normally much louder inside as well as outside the cockpit.
Irritates me how quiet my friends RANS S7 is with the same engine and
prop I am flying. ;-)

Subject: | Re: Headset Modification |
Larry,
Might be worth a call to QT. He's 'local' for me, and I bought mine by
walking into his office. Nice guy & would probably work with you on the
issues. I haven't used mine in an open cockpit, so don't know about
whether wind would affect boom position (but suspect that it should
remove it from your head before it actually bends the boom, assuming
that it isn't defective). No experience with open cockpit wind noise on
the mic either (except getting it in the flow of the cockpit vent, which
triggers *any* mic), but I have heard of some people getting the boom on
backward & talking into the noise cancelling port instead of the front
of the mic. Might be worth a check. Also, if the port gets clogged with
debris it will kill the noise cancelling function of the mic.
Agree that active noise cancelling doesn't do that much in open cockpit;
most of the problem is wind noise, which is *much* higher frequency than
even a 2 stroke. That's where good physical seal and a bit of mass
really help.
John,
Are you talking about iphone/mp3 player type buds that basically hang in
your ear? If so, be aware that using those inside a set of regular
headphones will not reduce noise much if any over the headphones alone.
Yes, you will likely be able to hear better than with headphones alone
(for a short time), but all you're doing is making the volume of the
radio reception louder, which is *adding* to the ear's total noise
exposure. Any of us who have flown for a number of years, and/or abused
our ears in other ways (I did concert sound work in one of my previous
lives) need to not just hear today's radio comm, but keep whatever
hearing we have left. :-) There are in-ear models that actually 'plug'
your ear just like industrial earplugs (not as cheap), or you can have
custom molded inserts made, (not cheap at all). What's your remaining
hearing worth?
As to noise levels in RVs vs Kolbs, I can't compare. But I have flown in
the back seat of an Aircam with two 912s. Didn't seem that bad at the
time, but maybe the 912s were cancelling each other. Or I was having too
much fun to notice the noise...

e. The Halo actually has the speaker elements mounted on the headband, with
small tubing connecting to the ear plugs. I would have thought that the Cl
arity Aloft would be even quieter. Are you sure you had a good seal between
the ear plugs and your ear canal?=C2-

I just finished modifying my Sig S45 headset with a set of "ear buds". Usin
g a "pencil solder gun" I had no problem at all with soldering the wires? t
o the speaker. Perhaps it was the type of flux core solder that I had.

I also bought the QT Halo headset, and I liked it for the most part. I had
no problem hearing the radio, in fact I had to turn it down quite a bit, an
d the best part is that I could listen to my music while flying. Not very s
atisfying with a normal headset. I however was not a fan of the mic. I put
an Oregon Areo mic cover on it and it helped a lot, but the "boom for the m
ic was as limp as 30 day old celery. I finally taped it to some alum wire t
o give it a bit of a spine. Other wise I had to hold it in front of my mout
h if I wanted to talk to some one. My cockpit is just a cover (factory wrap
around) over the area that I sit. If I turned my head it would crack the s
quelch and I would get a shot of full motor noise. So it was necessary to t
urn up the squelch a lot to keep it from cracking.
=C2-
You asked about seal, and I did have a good seal, but you also pick up ambi
ent noise through the bones that surround your ear as well. While I could h
ear great, I felt that the noise of that HKS was still too loud. I was cons
idering =C2-using a set of ear muffs to help with the noise. To be clear-
I never had any problem with hearing the radio or my music. My wife howeve
r often mentioned the motor noise was quite loud, and there was occasional
static. ( I think that there are better mic's out there than the one that t
hey use.)
=C2-
I have a base station here at the house so I can talk with the wife to get
her input on clarity on her end of the conversation. =C2-
=C2-
I decided to try adding the ear buds to my Sig S45's. I have found them to
be the best option for me even over ANR headsets. ( The ANR is set for GA a
nd works best on the 2400 RPM's of those engines. Ours turning 6000 RPM, ar
e out of the range that they generally work best at.)
=C2-
However wearing glasses I was not happy with the noise even with gel ear se
als on the S 45's. I felt that I had to turn the sounds that I wanted to he
ar up to the point that my old experienced ears would be still getting dama
ging noise levels. I could not hear my music very well and if I played it a
s loud as I needed to hear it at all in the plane, it would cause me to win
ce at that level out of the plane.=C2-
=C2-
After completing the modification I rolled the plane out for some touch and
go's. I plugged the ear buds in, covered my ears with the headset, and fou
nd that I had to turn the volume down on both the headset and the music rad
io for the first time. The noise level was substantially reduced from both
the Halo set and the S45 before modification, with the ear buds. Upon landi
ng my wife also confirmed that on her end the transmissions were a lot clea
rer, louder and without static.=C2-
=C2-
I will be using my Halo set as a backup. There was that much improvement.

Thanks Malcom.

Subject: | Headset Modification |
The MKIII suffers from the drum effect. Prop and engine noise is magnified
and confined to the enclosed cockpit. Open cockpit is not as loud.
Wouldn't do me much good to hand an ear bud on my ear. I've been wearing
hearing aids since 1978, while still on active duty and drawing flight pay.
Larry shot me a bc to get good ear buds that actually seal the ear canal.
The DC H-13.4 do about as good a job as any passively. The additional
passive noise reduction of the ear buds should allow for me to hear with
lower radio/intercom volume.

Larry,
Might be worth a call to QT. He's 'local' for me, and I bought mine by
walking into his office. Nice guy & would probably work with you on the
issues. I haven't used mine in an open cockpit, so don't know about whether
wind would affect boom position (but suspect that it should remove it from
your head before it actually bends the boom, assuming that it isn't
defective). No experience with open cockpit wind noise on the mic either
(except getting it in the flow of the cockpit vent, which triggers *any*
mic), but I have heard of some people getting the boom on backward & talking
into the noise cancelling port instead of the front of the mic. Might be
worth a check. Also, if the port gets clogged with debris it will kill the
noise cancelling function of the mic.
Agree that active noise cancelling doesn't do that much in open cockpit;
most of the problem is wind noise, which is *much* higher frequency than
even a 2 stroke. That's where good physical seal and a bit of mass really
help.
John,
Are you talking about iphone/mp3 player type buds that basically hang in
your ear? If so, be aware that using those inside a set of regular
headphones will not reduce noise much if any over the headphones alone. Yes,
you will likely be able to hear better than with headphones alone (for a
short time), but all you're doing is making the volume of the radio
reception louder, which is *adding* to the ear's total noise exposure. Any
of us who have flown for a number of years, and/or abused our ears in other
ways (I did concert sound work in one of my previous lives) need to not just
hear today's radio comm, but keep whatever hearing we have left. :-) There
are in-ear models that actually 'plug' your ear just like industrial
earplugs (not as cheap), or you can have custom molded inserts made, (not
cheap at all). What's your remaining hearing worth?
As to noise levels in RVs vs Kolbs, I can't compare. But I have flown in the
back seat of an Aircam with two 912s. Didn't seem that bad at the time, but
maybe the 912s were cancelling each other. Or I was having too much fun to
notice the noise...

My hearing has gotten so bad and the noise level is so great in the MKIII it
takes the fun out of flying. Biggest complaint I have trying to knock out 8
hour flight days. Noise is extremely fatiguing.
BTW: No cockpit noise comparison between a Kolb and an RV4. Kolb is much,
much louder and of a much higher frequency, engine and prop. Pushers are
normally much louder inside as well as outside the cockpit. Irritates me
how quiet my friends RANS S7 is with the same engine and prop I am flying.

Charlie,
I really do not have any substantial complaint about the Halo headset.
Yeah the wimpy mike boom is a bother, but not a real complaint. I feel that
in the normal course of things it is something that the manufacturer would
clean up in due time, but not enough of a problem to be a deal breaker. The
reason that I am using the S45 with ear buds is just that it is better, and
quieter. If I was flying a C150, I would use the Halo. In my operation
however, it just isn't the best one.
