An important meeting is underway .
When a speaker faces the microphone directly, their voice is clear and strong; however, if they turn their head slightly, the voice becomes noticeably softer. Someone flipping through documents nearby can be heard clearly by the microphone; however, when a colleague sitting in another direction speaks, their voice is not fully picked up.
The microphone is right on the table, so why does it "hear" from one direction but "ignore" the other? The answer lies in the microphone's directionality.
