Hello Jos



I have used three types of anr.  My experience is that you get what  

you pay for. I used a cheapo "Pilot" set for several years. They were  

OK, they worked reasonably well but they were not robust: the strain  

relief on the cable was inadequate and a solder joint failed at an  

"inconvenient" time; also, one of the jack plugs fractured when it  

took a small knock. I also used an ebay bargain second hand Peltor  

set which I believe was only marketed in the US. That was rubbish on  

active noise reduction although like all Peltors it has good passive  

noise reduction and is very tough. I decided to stop messing around,  

and so I bought a Bose set 2 years ago. Astonishingly expensive but  

the best of the three I've used. The passive nr on it is minimal but  

the active nr is terrific. Fortunately, my wife never saw the invoice...



One other thought. I have some special earphones for use on a  

motorbike (iPod, satnav etc). These are moulded to the shape of the  

individual customer's ear so they allow almost zero ambient noise in  

and therefore enable you to hear with the sound volume at quite a low  

level. The supplier (Ultimate Hearing) told me they could make a set  

if I wanted with the right impedence and the right jack plug to work  

in an aircraft - it might make a useful experiment although it would  

need an additional mike, of course.



Best wishes



Willie

Second attempt - one picture in each mail !



Dear Jos and all Europaphiles



Wow an opportunity to push what I do ! Sometimes.



So long as you don't have H20-10 (H10-20 is OK)



I convert headsets to ANR using a kit from Headsets Inc in

the US. I have done quite a few.



Two ways of doing it (actually also others) as per the

pictures

attached.



I don't do it quite the way they suggest but my method is

an improvement !



In my Europa I do not have jack sockets. I have 5 pin XLR

sockets and my headsets are converted with the ANR modules

and they take their power from the XLR socket. I have an

adapter if someone wants to use their own non-ANR-non-XLR

headset.



I could take pictures.



If you want to retain the jacks then I could provide two

sockets-with-9v-regulator-chip for installation in your

plane. This is shown with the new lead in the "AMP_2"

image, and you would get battery boxes to go with the

headset if you took it to another plane.



Or I could sell you the kit(s) and cables, it isn't rocket

science !



eMail me direct for further details



The ANR effect is not as good as Bose but it is 1/4 of the

price, and avoids having yet another headset or two

stuffed in a drawer. It is, however, as good as, or even

better than the DC ANR set.

Jos-

  

 There was an excellent article in Kitplanes about a year ago comparing them all.  They rated one of the Telex sets as best bang for the buck.  I tried the set on at Lakelnad last year and liked if very much.  I don't remember the model, but I'm sure someone at Telex could help.  Also, Kitplanes will reprint an article for a fee.  You may want to e-mail them and see if you can get a reprint.  My magazine is gone.

ANR Headsets



A word of warning on the use of ANR headsets. If your intercom setup dosent 

include squelch on the mic circuit it can make the best headsets appear 

worse than useless. Our intercom was built into the ICOM A2000 radio and 

these do not have any microphone squelch.



We initially used a set of cheapo "Skyforce" ANR headsets and to be honest 

they werent up to much (or so we thought).



So we upgraded to a middle of the range Sennheiser HMEC300 and there was 

little or no improvement - that is till we realised the mics were picking up 

the cockpit noise and feeding it back through the intercom. We have now 

fitted a separate (portable) intercom with separate squelch control and the 

reduction in noise levels is considerable.



If you arent sure if the mics are feeding excessive noise into the amplifier 

circuit try muffling them with a towel and seeing what difference this makes 

to incoming transmissions (or simply to the ambient noise in the headsets) - 

in flight of course.



Im not saying dont buy ANR as I would opt for them every time. Given the 

choice I would have opted for the BOSE ones it was a hell of a job 

persuading Mrs P that £350 (each) was worth spending never mind £600 !!!

BTW - IMHO noise cancelling microphones dont seem to cancel out very much 

noise - maybe someone with a superior technical understanding might 

volunteer an explanation.

Any intercom within a radio with only one microphone

circuit (rather than one per headset) is not a proper

intercom. Any paralleling of mikes will cause problems if

you parallel a DC set (low impedance) with almost anything

else (high impedance).



And as Carl says a lack of squelch also makes it not much

use as an intercom.



So always use a separate intercom.



Richard Holder who hasn't done any fibreglassing but

certainly knows about radios, headsets. electrics and ANR

Hi Richard,



If it's possible to equip my DC's 20-10 with ANR, i will be very happy. But please explain a bit how it's working, is there a mike on the box or on the headphone(s) to pick up the sound to be neutralized? How much work is involved in the change-over? Btw, i have an Xcom radio, with a built in proper intercom, with good intercom squelch. 



Did a spectrum analysis on a pair of great sounding Bose speakers once, to discover that the frequency response was not even close. This was after complaints from a customer, a violin builder. But that was 20 years ago.

I have a couple of Lightspeed 15xc's which work just fine.  At $350 USD, 

the price wasn't bad, either. Don't know if they are still available, 

though...

Jeremy,



To your question:

 	  Quote: 	
		   I have heard it said that the Bose ANR headsets (Aviation X) aren't

 brilliant with a Rotax - due to the frequencies being so much higher than

 with a Lycosaurus. Can anyone out their comment?




	


I have used this headset for about two years, but have no experience with

other ANR sets.  To my ears they are as effective (and very noticeably

effective) in my Europa with Rotax as in Cessna 172s and Piper Cherokees

with Lycomings.



Apart from the comfort of much less noise in the ears, a side effect is that

you speak in a more normal voice on the radio - no need to "shout" to

overcome noise.  Also, using the cell phone via an adapter (I have

SafetyCell's) for the headset's mike and headphones works fine.



I have padded the metal going over the top of my head to avoid scratches in

the window in bumpy air.



Regards,

Svein

 Hey Jeff,

  

 I will echo what you've said about Lightspeed. I have a set of 20XL's and  I've been using them almost daily for about 5 years now. They were under  $400/ea from Spruce. I've used them both with the Europa/Jabiru and the  Ximango/Rotax and they work equally well. I've also used them in a Pawnee,  Citabria, C-210, Navion and a T-6 excellent results. Battery life  for the ANR seems to be in excess of 40 hours on two AA batteries. I  once broke part of the earpiece after sitting on it and Lightspeed sent  replacement parts at no charge. 

  

 My only gripe is the audio quality from my XM radio isn't the best,  IOW, not enough bass response. However, after looking at the schematic  for my Flightcom intercom, the lack of bass in the audio probably has  more to do with the size of the capacitors they used in the intercom as opposed  to a problem with bass response in the the 20XL's. I would highly recommend  Lightspeed headsets.

I borrowed a friends Bose headset, and was not that impressed due to the lack of passive noise reduction. 

I did not realise how much high frequency clatter the 912S generates. 

Checking the ANR headsets at Oshkosh last year, I liked the Sennheiser, had excellent passive reduction, but priced  

high enough to make me stay with my old Sigtronics set for the time being.
