[CQ-Contest] Noise canceling headphones

[Eric Scace]

I don't think noise canceling headphones do much to shut out the
loud-mouthed operator sitting next to you.  That does not meet the profile
of "noise".  They will cancel white- and pink-noise sounds such as the fans
on amplifiers.

The noise cancellers work great in VERY noisy environments with lots of low
frequency noise. Most are made to attenuate noise by 15-20 dB in the 60-150
Hz region that are generated by propeller driven airplanes. I couldn't live
without mine in the plane, but I don't think they are worth the money or
effort for radio use, unless you have some really loud operators in a M/M...

 I just tried a pair of Sony MDNR5's and they look promising.
 I am getting ready for a multi multi operation next year, and
 need a set of headphones for a noisey environment. I usually
 use one of a couple of pairs of Sennheiser phones that I have,
 and they are fine for a relatively quiet environment. I
 should mention that these are for cw purposes, and I don't
 want to be distracted by the ssb op next to me...

 Thanks for the time.
