First, the standard gesture
1. Maintain an appropriate distance of 10 to 15 cm
It is necessary to keep the distance between mouth and microphone properly. If the distance is too close to the mouth, the sound will be too loud, and you may have issues with certain plosive (like P’s and B’s). The plosive also affected by the angle. Try to change the angle by as little 20 to 45 degrees so you can eliminate that issue. You need to practice with a mic frequently and find what works best for you.
2. Hold the upper or middle part of the microphone
3. Try to keep the microphone head facing the mouth
The old-fashioned microphone, the radio position is located at the top of the microphone, so when talking by the microphone, try to raise the microphone a bit, so that the sound is "filled" from the top of the microphone, which can make the microphone sound better.
4. Avoid the microphone facing the speaker
Second, microphone directivity
If the microphone can only receive sound in a certain direction, it is called a directional microphone. Usually the front of the microphone has the highest sensitivity and the sensitivity behind it is almost zero. This directional microphone is especially important on the stage because it only receives the sound from the front, and the sound from the side or the back is rejected, thus avoiding many unnecessary noises. When using it, you must be careful about the direction of the microphone, the direction is wrong, and the received sound is wrong.
It is a microphone that can receive sounds from all directions, such as the drums of the entire drum set. But if you want to receive a clean and simple sound source, a non-directional microphone may not be a good choice
The directivity of the microphone will also be degraded by the proximity of the two microphones. The degree of deterioration is proportional to the distance between the two microphones. Therefore, the user should avoid holding two or more working microphones at the same time to avoid deterioration in volume, frequency response, and directivity. If you want to use multiple microphones at the same time, you must pull the microphones apart by at least 30 cm.
