Shotgun microphone

The peculiarity of this kind of microphone is that any sound not coming from the pointing direction enters through the slits and, due to the tube's length, it undergoes countless reflections which pretty much nullify each other. The sounds coming from the pointing direction on the other hand, pass through the tube without any obstacles. This microphone is used to pick up a specific sound source within the space, even at great distances.
