ELECTRONIC NOISE
CANCELLATION
DESCRIPTION & TECHNICAL INFORMATION:
How it works.
David Clark’s Electronic Noise Cancellation (ENC) headsets feature the latest
advances in electronic noise cancellation technology. They’re specially designed
for pilots of aircraft which generate noise at lower frequencies. Headsets relying
on passive noise control methods alone cannot suppress low frequencies as
effectively as mid and high range frequencies.
Opposites protect.
Unlike passive headsets, David Clark’s electronic noise cancellation headsets use
an electronically produced signal to cancel the offending noise. Low frequency
noise is sensed and an opposing signal of the same sound level is generated.
The result is cancellation of the noise before it reaches your ears.
Hear what’s important.
With low frequency noise canceled, you’ll hear essential communications clearly,
and with less strain. Sounds within the range of the human voice, such as air
traffic messages and conversations with other pilots, will be easier to verify.
Such improved audio comfort leads to alert, and safer flying.
