 |
|
Flew the MKIII for while this morning, tried out the noise canceling earbuds, and there was a plus and a minus.
The plus was that they really do cancel out the noise. Turning the ANR switch off and on shows that the ANR function removes the deeper rumble of the prop, and part of the engine noise. It makes the engine noise seem smaller and further away, if that makes any sense.
For comparison, tried various combinations, just the Flightcoms without the earbuds, the earbuds without the Flightcoms, the earbuds with the ANR turned off, etc., the earbuds knock out about as much noise as the Flightcom headset, but each has a different quality. Once you put the headsets over the ears with the earbuds in, it cuts down the total noise a lot more, as you would expect. I think it is about the same effect you would get if you put in a pair of tapered soft foam hearing protectors, and then put on your headsets. Once you have both the earbuds and the headsets on, turning on the ANR cuts the prop noise out of the mix, and also makes the engine a bit quieter. And since I had my .mp3 player along, plugging it in and adding some Moody Blues to the mix was also a plus... The total amount of aircraft noise making it to my ears was low enough that you could listen to music without having to turn it up much.
The minus was that I could not hear the tower, approach or ATIS. Didn't have any friends to yak at, but I suspect that 122.75 wouldn't work either. The earbuds did not allow what was coming out of the Flightcom speakers to make it into my ears. So I think what I will do next is make an adapter plug and jack so that I can unplug the headset/speaker side of the Flightcoms, leave the mic plugged in, and plug the earbuds into the aircraft jack where the Flightcoms normally go and try that. Use the earbuds for aircraft radio audio and see what happens. If I can figure out how to make it work at all, it ought to be quite good.
Whoops, better make that adapter with a Y-setup, or the mp3 player will get left out. Can't be having that, ya know...

I have been flying for about a year with Sony ear buds under my active noise canceling headphones. I have a matched pair for my passenger who doesn't get active noise canceling. I connect them to my intercom and disconnect the headphone ear peices. That way I can hear music but the intercom cuts the music when there is radio traffic and it adds a welcome additional level of noise reduction. The ear buds have sound quality superior to the headphone speakers. Your active ear buds may do a even better job at about the same price.
