The reason why it takes time to warm up your voice

Does it take you a lot of time to warm-up your voice? Ten to twenty minutes is the average length of time it takes most people. The voice needs to warm-up. A warm-up is commonly done before singers sing in a performance, or in advance for public speakers who use their voices for long periods of time. If you take too long to warm-up your voice prior to a vocal performance, the reason is probably because you are doing too many exercises or the exercise are too long in length. Breathing, stretching, drinking, and a run through of the scales from low to high are just some examples. If you take a lot of time to warm-up your voice before singing, your muscles may become too hard around the throat area. Specifically if you warm-up your voice for more than one hour, the throat will definitely be tired before you even start singing or speaking.
Vocalization is operated by the movements of the musculus extrinsic laryngis. You don’t need extreme muscle strength to produce a loud voice, because the volume of the voice is not proportional to the momentum of the musculus extrinsic laryngis.
The 5 factors of Creating Voice

Note1:If you get tired to sing a song really early after starting, your musculus extrinsic laryngis might be hard. The reason why is low or poor blood circulation due to the stiffened muscles. If you have poor blood flow to the muscles relevant to vocalizing, then enough oxygen and nutrition will not be carried or delivered to those muscles.
The lesser horn of the cartilage is more than likely pressured due to LDP (larynx deep position) when opening the glottis, causing air to leak and making it hard to control the voice. Dry vocal mucosa also contributes to this status, resulting in having a problem with falsettos. Proper density and moisture of the throat from the vocal mucosa is necessary, so always be aware if your throat is dry when you are singing. Muscle power is being used every time the glottis opens and closes, and excessively doing this action too much during a warm-up will cause the muscles to tire around throat easily. When you warm-up, warm-up slowly and in moderation. Even the slightest form of excessiveness when warming up can result in negative changes to your sound and throat muscles.


Bone Conduction Headphones

The following picture is of bone conduction headphones, the brand name is : AUDIOBONE FIT


This headphone does not use the longitudinal waves in the air. The electrical signal is converted to vibrations which conduct around the cochlea, via the temporal bone.
You can really feel the sound conducting through your bones when using these headphones.
However, in my opinion … there is not enough sound pressure, and the bass sound is not so strong. Also, the richness of sound is limited when using bone conduction headphones.
I did put high-end headphones over the bone conduction headphones to listen to the music. I felt a sense of depth in sound. I could even imagine the size of the stage, the position of the singer, and was able to feel like the music was just like a real concert through the headphones.
However, the sound was accurate in overlapping with the vibrations.

Note1:If the bone conduction headphones were to be made for vocalization, it would have to conduct around the styloid process.
The stylopharyngeus muscle and the stylohyoid muscle attach to the styloid process to suspend the larynx.
The direct conduction would make these muscle move easily, and I believe it would result in a positive effect for the voice.

Skull 50

I used FOSTEX TH-900 for test,and this headphone is really able to duplicate the natural sounds.
