Boom (gooseneck) Vs ambiance microphone

[Ludovic Launer]

Hi,

I saw a glider recently with a "ambiance" microphone installed in the
instrument panel (facing the pilot, it only takes a small hole in the
instrument panel).

I was wondering how this performed compared to what we're used to = goosneck
microphone on the cockpit side.
I like the idea, it's saving space, and you have one thing less in the way
when getting in/out of the glider.

Has anyone been using an ambiance microphone in the instrument panel (or
somewhere else) ?
Any etra noise ? How does it perform ? Is that acceptable ? Can others hear
you correctly ?
Do you have to shout or speak normally ?

Regards,
Ludovic

Bonjour Ludovic: I have always been using panel mount
microphones on my gliders, and they perform just perfectly.
They take up very little panel space, usually less
than 20mm diameter, they are light and unobtrusive
compared to the boom type. Radio communication is absolutely
normal, you only have to raise your voice level when
there's a lot of ambient noise (flying fast with open
ventilation, or high vario volume), otherwise you always
transmit 5/5. They are not suitable for motorgliders,
of course.
Good ones are expensive: 110-150 Euro, but I once made
one myself with the mic capsule extracted from a cheap
handheld mike, and it worked 100% ok.
I would not do without one such microphone now (by
the way, I have two brand new gooseneck microphones
for sale: interested, anyone?)
Cheers,
Flavio

We had one in a DG202 we had about 7 years ago. It worked quite well
until the glider was destroyed in an accident.

We replaced it about 6 months late, the new one now has a boon
microphone. On a trip to Feshie, I met a radio engineer who gave me a
circuit for a voice operated microphone. Unfortunately this used a chip
which is now obsolete, so I never built it.

The boom mic is sort of OK. The stalk needs a Viagra injection, and you
need the head of the mic. very close to your lips.

Hope that helps

What brand names are the panel mount microphones so I can
check if they are available near me.

This sounds excellent! Where can I buy a quality specimen?

[OscarCVox]

Does anyone know if the noise cancelling mikes used as hands free with mobile
phones would work?( impedence etc) I was thinking of mounting one just behind
the canopy frame at head level. They seem to work ok in a car with highish
background noise levels

[Tom Hollings]

I use the built in microphone in the Icom radio, which is mounted on the
right side of the cockpit about 300mm from my mouth. The only problems occur on
aerotow, when I have to raise my voice.

All the best,

Tom Hollings.

(I don't take any money from them...)

[Ludovic Launer]

Yes, thanks, that's just the one I had in mind.
I was wondering if anyone was using a more "off the shelf" component
though...

This is what I like to use. It's a cheap single over-ear headset with boom mike.
It uses a PTT "box" (about the size of a matchbox). I bought it from Radio Shack
for about $20.

[Flavio Formosa]

I once self-made one by extracting the mic capsule
from a 25€ hand-held PTT-mike (the type used with ground
VHF units) and wiring it to the mic harness of the
radio (Becker AR3201). It was cheap and perfectly functional.
You need some soldering skills though, and you may
want to insert it in the panel in a presentable fashion.
I had glued the capsule behind a hole on the back of
the panel, and glued a black round metal grille on
the front (this latter taken from a discarded walkman
headset's earpiece!). If you want to see the effect,
go to www.segelflug.de on the segelflugzeug-testberichte
page, find the LS7WL test report and check the picture
where my instrument panel is (the one with a Filser
DX50 on the top row): the home made mic is on the right
hand of the panel at mid height. Good luck!

Hi,
Were you able to buy that microphone?
Does it work as well as a gooseneck?
Is there a retailer in the USA?
Thanks
