Can two vertical microphones hear the whole audience when reading poetry?

Of course. The microphone for poetry reading is perpendicular to the ground and has a slight angle. Put it on your chin and don't talk to your face or mouth. The two vertical microphones used for poetry reading can hear the sound in the whole audience. The directivity of the microphone is a heart-shaped area with a 45-degree angle. When speaking normally, the microphone should be parallel to your body and the tilt angle should not exceed 45 degrees.
