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.


A Clinical Study: Does the voice influence how others perceive your appearance?

I ran and analyzed a clinical vocal study to determine if a person’s voice influences how others perceive their appearance. In this experiment my focus group test participants consisted of 10 people, all single men.
I split these 10 into two groups labeling them ‘Group A’ and ‘Group B.’
My testing subject is a female voice actress. I took a photo of her and edited the woman’s photo to be unattractive using Photoshop. Then I had the voice actress record two different speaking voices to use for playback in this experiment.
The first voice she recorded is a good voice, which is a clear sounding and beautiful. The second voice she recorded is a bad voice, which sounds hoarse and husky.
I let ‘Group A’ listen to the first voice (the good voice) and ‘Group B’ listen to the second voice (the bad voice). Following their observation I evaluated them by asking them this question, “This is a photo of the woman who was singing, in your opinion, do you think the woman in the photo looks attractive?”
Regarding the results of Group A (the group that heard the good voice), 2 people answered: “She looks so attractive.” 2 more people answered: “She is neither attractive nor not attractive.” The final participant from that group answered: “I don’t think she is attractive.”
On the other hand, regarding the results of Group B (the group that heard the bad voice), all 5 participants answered, “I do not think she looks attractive.”
Despite the fact that they all saw a photo of same woman, both group’s answers were different. This is because the voice significantly influences how others perceive a person’s appearance.
So the majority of both vocal study group participants were clearly influenced by the quality of the voice they heard when basing an opinion about that person’s appearance.
In conclusion, I believe that anybody can change how other people view their appearance based solely on the underlying factor of a good speaking voice.
