|The Technology Behind GN Netcom SoundTube Headsets

Making the best of a better situation.
Maybe you're familiar with the "good, better, best" hierarchy that
most companies use to position their products, solutions, or technologies. In
the headset world, the same rating system applies when talking about professional-quality
headset tops. Typically, the no-frills basic models make up the "good"
tier. High-end, noise-canceling tops rank as the "best." In the "better"
range, you'll find many styles, including tube-style headsets.
The technology behind these headsets has been around for 3 decades and not
much has changedtill now. With the introduction of GN Netcom's SoundTube
headset technology, "better" just got
Just what is "voice tube technology"?
A tube-style headset top is comprised of a headband, speaker, and a clear plastic
tube. Sound waves travel up the tube and are absorbed by dampening material
affixed to the omni-directional mic located within the earpiece. As simple as
it sounds, it actually works rather well. The trade-off has typically been
a price tag lower than that of noise-canceling units.
The unique design of the GN Netcom SoundTube delivers strong and
consistent sound waves through the metal alloy tube to the mic where they terminate
precisely at the microphone every time.
The SoundTube's thin, alloy tube is engineered to eliminate standing waves,
non-traveling vibrations of certain wavelength and frequency which occur on
a medium of certain size. Standing waves simply resonate inside old-fashioned
plastic tubes creating a murky acoustic environment through which your voice
must travel to the mic. Not with
SoundTube, though. Thanks to the design of its
unique alloy tube, your calls are clear and crisp.
Is the GN Netcom SoundTube noise-canceling?
No. A noise-canceling headset uses enhanced mic design and electronics as well
as precise microphone positioning to eliminate background noise. Tube-style
headsets (SoundTube included) can pick up the din of a busy office and transmit
that to your caller. That's why these sets are not recommended for noisy environments.
However, in a quiet setting, a SoundTube headset offers excellent sound and durability.
