As a device which works by allowing audio to pass through an amplifier once
it has reached a particular threshold.  Commonly used in the process of
recording audio in all it's forms and in all it's associated industries.

the precision of the question is purposefully loose - one would assume that
the modern side chain-based noise gate (e.g. Drawmer DS201) has been
developed from a variety of technologies over the decades, in much the same
way that the Phonograph itself was merely a new way of using existing
technologies.  However, I would be looking at specific audio applications,
taking into account those devices which bear a similarity to what we see in
recording studios today, and those devices from which these are derived,
including devices that we now regard as noise reducers as opposed to gates.

Hope that clears it up!!
