Loud Cockpit

I understand manu's have to draw the line, but $100 upgrade rebate on only 1 headset and nothing for the other? F U customer is what I heard. I can almost completely guarantee you that Bose would not treat a (to that point) happy customer the same way. Now I will simply never buy, nor recommend, Lightspeed to anyone. I mean there ARE other headset companies. And I also guarantee you that on a $1,100 headset there is some margin.

No problem at all.

The mono inputs on the iCom's is the reason I went with them rather than some other brand.

The audio from the SkyView is very clear and I really like the AoA beeping.

These work very well, I had a problem with noise when the fresh air vents were open, but the mic muffs solved that nicely.

Actually around here (Phoenix) I want Betty to warn me about traffic (have Skyview Transponder so TIS traffic currently). Falcon has gotten very busy with over 100 trainers on the field, and the nearby airspace is just as busy. It would have to be some kind of multi-national holiday for the Standfield Stack (unicom Casa Grande has a ILS) to be empty. You'd be absolutely nuts to try and fly or land at the unicom airports south of Phoenix without a radio, let alone without some kind of traffic warning. My next big buy will be the ADS-B module for the skyview.

As for AOA, the beautiful thing about the Van's is it's pussycat flying - I mean you have lots of warning many different ways before you stall. Compared to other aircraft, even production aircraft it is a "gentler" stall and easy to recover. I do have the AOA system, that's on the list for calibration.

Classic Aero makes beautiful carpet pkg. for the cockpit that has noise insulation under the carpet in front of the seats. A great product. I have the Icom A-210 but decided to install the new PS Engineering audio panel (LSA version). The Com is wonderful and provides lots of options to input music, phone etc, more radios in the future - not sure if that fits budget or mission.

I also have found lately a noise problem with the "Bitchen Betty" output from Skyview. There is a fix to put a resister in line to limit noise - the process is detailed on the Dynon Forum if that becomes a problem with your setup. I have yet to do it but will get it done soon.

Good Luck

Want to thank everyone for their input! Dialing back the gain on both headset mic's helped alot.

I am also trying to quiet the engine noise that radiates into the mic when I PTT. I already adjusted sidetone and that helped. Cutting a finger off a pair of leather gloves is a good idea but why would u cut a hole on the side of the mic NOT facing the pilot? If I'm not reversing the headset, why cut two holes?

My Lightspeed is back at the factory for its second repair in 7 months. Not pleased with its noise cancellation or the quality of any product that requires two repairs in such a short period of time. Thankfully, it's still under warranty.

Thx.

Passive microphone noise reduction is mechanical. They allow ambient noise in both ports, front and back.
Then, when you speak... the pressure waves only enter the front. The mic element responds to your voice... but less so to the ambient noise hitting both sides. Keep the mic touching your lips... or it works very poorly.
Hope this explanation makes sense.
BTW I have met the Lightspeed folks for over a decade now at the shows. Also sent many units in for repair under warranty. They are a great company.
The extreme reaction of one customer posting... and using simple abbreviations for foul language is pretty border line behavior on this forum... I am pretty sure. Now if I could only get my headset to decipher the accents on the radio around PHX... I would love that technology.

Edit: see above post. Some work as described, others like this (same principle):
Noise cancelling mikes (you do not want anything less) work by having two mikes, back to back. The signal is differenced (subtracted). Noise from sources more than a foot or two away tend to be about equal on both sides, so after subtraction you get zero. Speech from your lips (0.1" away) is much louder in the mike facing your lips than the other, so after subtraction there remains a strong net signal. To keep the cancelation working correctly, both sides need the same size hole. If the mike is not very close to your lips, it will tend to cancel your speech!

Bob, can you send me a reference for a microphone manufacturer that uses that technique? It sounds promising. I have customers who are trying to quiet an OV-10 Bronco for fire season. All the microphones I have taken apart have only one element. I know the earcups have microphones for cancellation though...
