More equals less
Where aviation headsets are concerned, the
prospective buyer should focus on performance, as well
as comfort and costs. And noise or sound attenuation
is certainly an area in which more is less: The greater
the drop in decibel levels, the lower the noise coming
through the headset's barrier action.
Sound, as measured in decibels, doubles with every
3-decibel increase - or, conversely, falls in half for every
3 decibels of attenuation.
So a headset with a 29-decibel noise-reduction level
is letting past one-ninth the sound pressure present. A
44-decibel reduction blocks all but 1/15th of the sound
pressure present.
Here, the higher the measured decibel reduction, the
lower the amount of noise that gets through.
Consider some of these options in headsets, or
headphones, as some call them.

A sampling of modern headset technology
A lengthy review of the options available in headsets
drove home that the list runs long - too long for this
article - and absent an opportunity to try most of them,
we'll leave the reviewing to another time.
So, we look at options in various price ranges: up to
about $200; from $201 to $500; $501 and more.
Up to $200
A good selection exists here, ranging from about $80
to $200, with noise reduction levels of about 24 decibels
nominal. Otherwise, these are generally passive sets,
many of them with stereo capability when connected to a
source capable of producing stereo output.
One particular surprise was a passive-reduction
model priced under $125 - with Bluetooth.
$200 to $500
As prices rise into the $200 to $500 range, more and
