The pointing of the gun is that the microphone picks up sound from different directions. In the field settings, the most important thing is to confirm the type of microphone you are using to reduce sound feedback and where the monitor is best placed depending on the directional use. In the work room, you can use sensors with different characteristics to make changes. It's like laying out a certain decoration during recording, or an proximity effect.
Pointing microphone: Classified according to polar form, it is much more sensitive to sounds coming from the front than to sounds coming from behind. The pointing microphone has two openings at both ends of the diaphragm, one on one side. The vibration of the diaphragm depends on the phase relationship, depending on the pressure difference at both ends. A fine acoustic filter at the front of the rear sound hole is delayed so that sound coming from behind can reach the diaphragm and cancel out from both the front and rear sound holes at the same time, so that the polarity of the pointing microphone is centered.
Noun explanation: proximity effect
Each pointing microphone (heart-shaped, super-heart-shaped) has a so-called proximity effect, and as the microphone approaches the source, the low audio rate response increases, so the sound is fuller, resulting in a proximity effect. Professional singers often take advantage of this effect. To test the effect, try to move the microphone closer to your lips as you sing, and then listen to changes in sound.
