Actually the sound detected by a shotgun along its length is used only for
noise canceling, thus rejecting the side noise. This characteristic is
exactly what we desire in a parabolic situation as the result is a highly
focused sound source with excellent side rejection.
Please reference the following article

- Shotgun
The Shotgun gets its name from its long, formidable-looking isolation tube.
These microphones, shaped like the barrel of a shotgun, are designed to be
highly directional and have high rejection to sounds originating from the
sides. Shotgun mics are one of the most commonly used types for on-location
work due to their ability to isolate the talent from off-camera sounds. A
common misconception is that shotgun mics somehow zoom in on a remote sound
source. This is generally not the case. To illustrate, imagine looking
through a paper-towel tube. You are not actually seeing the image more
closely, only isolating some specific portion of it. In the same way,
shotgun mics do not really "zoom" in on the remote sound source, they only
isolate it. Some shotgun microphones do include on-board amplification or
processing circuitry which helps draw in distant sounds more effectively.
Schriber Acoustic also offers a model with selectable pattern
characteristics to give the microphone increased application versatility.
