Boom (gooseneck) Vs ambiance microphone
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 |

Do you have to shout or speak normally ? 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 -- Mike Lindsay |

What brand names are the panel mount microphones so I can
check if they are available near me. gary "Flavio Formosa" wrote in message ... Bonjour Ludovic: I have always been using panel mount microphones on my gliders, and they perform just perfectly.

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

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 |

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. |

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... Try this: http://www.md-flugzeugbau.de/flymic.html |
