Understanding sound waves and the relevance of a good microphone

Most people try to let out a loud voice immediately after they grab the microphone when performing Karaoke.
However, even if you exhale a lot of breath, the microphone only catches some of that sound.
The point is that the wave of air, meaning the vibration of air, transmits to the diaphragm then the microphone. The exhaled air carrying the sound is not projected directly to microphone, it is spread over a varied range of area.
Voice cannot be generated without airflow. The vocal folds vibrate by means of airflow.
When singing the generated voice (fundamental voice) is edited while passed through five resonance chambers. The sound wave then goes to the diaphragm, after that travels to the microphone. Some microphones and are superior to others and specialize in capturing the sound waves carried in exhaled air.

The condenser microphone was known as the best microphone for singing in the past, because it could capture an exhaled sound wave precisely. It is very expensive.
A dynamic microphone is also good in comparison. You do not need to sing so loud because it can capture your voice well.
In order to get the most out of a microphone its best to understand the mechanics and process of exactly how the voice is transmitted to the microphone by vibrating air. Familiarize yourself with the abilities the microphone offers to compliment your type of singing and vocal style.

Note1:I personally like the AKG C12VR which is a tube condenser microphone. Mainly because the tube can duplicate voice quality faithfully. In conjunction I usually use Sinfonia 25th Anniversary model as a tube amplifier.
