LDP is the condition in which the ‘Larynx has moved and is in a deep position.’ LDP has become so common, as vocalization evolves most of the general population have this condition. The types of LDP can be characterized. There are four types.
General LDP is when the hyoid bone, the thyroid cartilage and the cricoid cartilage get in a deep position.I’ve investigated, and 92% of people have general LDP. However, there are two other types of LDP, each in which only one singular part gets in a deep position. I refer to the first singular type as, “Upper LDP.” With Upper LDP only the hyoid bone gets in a deepened position. The second singular type is “Middle LDP.” In which only the cricoid cartilage gets in a deepened position.
Additionally, there is a final type of LDP, which I have only seen within an older age group. I refer to this type as, “Pituitary LDP.” With this type of LDP the larynx gets in a deepened position and is accompanied by extreme muscle weakness due to aging.
LDP is a condition not a disease and I have been successful in treating and fixing this issue in many people. Although, I have discovered that even if I cure any of the 4 LDP types, upper LDP is the most difficult/stubborn. Only in the case of upper LDP I have found that even with treatment success some small issues still remain or the condition returns later. This is because it’s easy to flex the lower part as well as the middle part of the larynx, but the upper LDP position of the hyoid bone gets in extremely deep and does not move forward and stay easily. The middle constrictor contracts toward the cervical spine and includes a lot of connective woven fibers. The larynx is suspended by the suspensory function (stylopharyngeus muscle and stylohyoid muscle) assisting in the ability to resonant the voice.
Be advised as I have mentioned in previous studies: LDP is muscle habit not a disease – Please do not get wrong idea.
The sound’s pitch is made in the vocal cords, and its tone is made in the five resonance chambers. The 5 chambers are as follows:
➀The laryngeal ventricle between the vocal fold and the vestibular fold (false vocal cord )
➁The piriform recess (the space between the vestibular fold and the epiglottis)
➂The pharyngeal cavity (at the back of the hyoid bone)
➃The oral cavity in the mouth
➄The nasal cavity in the nose (Figure1)
The pharyngeal cavity(➂) is absolutely the most important for vocalization.
The pharyngeal cavity’s space can change by moving the hyoid bone. The shape and hardness of the soft tissue can be also be changed, depending on how much or little activity/muscle training around the pharyngeal cavity.
The hyoid bone is suspended by the stylopharyngeus muscle and the stylohyoid muscle is in the air. (Figure2)
Furthermore, the muscles attaching to the hyoid bone are the : middle constrictor, the genioglossus muscle, the mylohyoid muscle, the hyoglossus muscle, the sternohyoid muscle, the thyrohyoid muscle, and the omohyoid muscle.
These muscles contract to fix the hyoid bone’s placement, and the voice is changed. This vocal change degree is determined by how smooth and precise that muscle group moves.
Note1:When comparing production of a human voice to a guitar, imagine the vocal chords are the strings and the pharyngeal cavity is the body of the instrument. The sound is made by the strings and is resonated in the body.
Note2:The words are made in the oral cavity, using mouth and tongue movements, and the sound tone is made in the nasal cavity.
Although the nasal cavity is a very small space, similar to a guitar it plays a vital part, which is to change the voice tones from vibrating air.
Vocalization is operated by the movements of the musculus extrinsic laryngis and the vocal cords.
When measuring the degree of LDP (Larynx in a Deep Position) muscles’ hardness, the meter reads between 30-80 tone. At such a high levels, the larynx, the hyoid bone, the cricoid cartilage and the thyroid cartilage are positioned deeper than normal.
LDP causes muscles to move slow and makes it hard to sing speedy or fast paced songs. This is because when trying to sing and follow speedy music, the muscles can’t react and keep up, it in turn causes hypertonic vocalization and hardened muscles.
I believe LDP should be fixed, and observed by those who have such issues.
By the way, LDP is just a condition of the throat – not a disease. Therefor treatment and improvement of LDP is always an option.
Note1:Besides the importance of having flexibility of the muscles relevant to vocalization, it’s also important move the cricothyroid articulation and the cricoarytenoid articulation smoothly to open and close the glottis.
The sternocleidomastoid muscle and the omohyoid muscle are intersecting on the side of the cervical spine.
When the sternocleidomastoid muscle is swollen or the omohyoid muscle floats, these muscles are touching each other. When this touching happens movements then become obstructed, which causes problems with vocalizing – such as:(1)Hard to let out the voice or to depress vocalizing (2)Make a boxy voice, because the resonance chamber gets narrower (3)Cannot let out a high-pitched voice because moving the cricothyroid articulation is obsrtucted.
Furthermore, some people naturally have conglutination with the fascia of the sternocleidomastoid muscle and the omohyoid muscle which obstructs vocalizing.
The sternocleidomastoid muscle is not directly relevant to vocalization but can cause poor blood flow/circulation in the superior laryngeal artery. This poor blood flow is because the larynx is pressured directly by the conglutination.
Note1:In the case of the conglutination with the fascia of sternocleidomastoid muscle and the omohyoid muscle: if you can make the space increase between the fascia and the muscles, you will improve letting out your voice. Please be careful, gentle and aware if you massage that area by yourself, because the intermediate tendon of the omohyoid muscle is located under the sternocleidomastoid muscle.
A singer or voice actor is an athlete of their throat and larynx. Professional singers are well known around the world, voice actors are often not so recognized. Although both professions share the same goal, which is to work/have a career surrounded by their vocalization. Voice acting is the art of doing voice-overs or providing voices for animated characters in various works, such as feature films, dubbed foreign language films, animated films, television programs, commercials, radio, comedy routines, video games, puppet shows, amusement rides announcers, audiobooks, podcasts and documentaries.
Both singers and voice actors need to display ultimate control with a broad range of styles and sound abilities. Understanding the mechanics of the throat, its muscles, and breathing techniques is just like a sport. This is because when involved avidly in sports people use their bodies to train their muscles. This training is in an effort to be in a good condition, suitable to excel as well as be successful in the sport focused on. Singers and voice actors are athletes, who are training in the sport of vocalization.
The kinematic performance needs of the throat for singers and voice acting professionals are as follows:
1.Flexibility of the musculus extrinsic laryngis
2.The muscular power of the muscles relevant to vocalization
3.Control in inhaling and exhaling breaths precisely
4:The specific technique/style of the vocalization or singing
Note1:We cannot control muscles relating to vocalization by ourselves. Each person has a different way of training and learning to establish control with the muscles used to vocalize. For some people it can be several movements, and for others it can even be a singular movement.
You do not need an echo effect added to a microphone, if you have a substantial size of the resonant space in your throat. This space is known as the pharyngeal cavity.
People who have their middle constrictor relaxed or less connective desmoplasia of soft tissue attaching the hyoid bone, can be classified as having natural resonant voice capabilities.
However, 99% people have their hyoid bone in that vicinity, which does not move very well.
If I massage the throat muscles and pull out (from the exterior) the hyoid bone while humming, the space of pharyngeal cavity can be made bigger.
The voice is made by vibrating air, echoing in 5 resonance chambers and then coming out from the mouth or nose. The sound and air which vibrates and travels then reaches to other people’s eardrums, thus other people being able to recognize the voice.
If you hum while pulling out the hyoid bone, even a small voice can echo very well. This is because the pharyngeal cavity has expanded. Even a slight expansion can be distinguished. This makes it possible to create a larger natural echo effect.
You can create a better echo in your voice by using this technique.
Note1:The thyroid cartilage and the stylohyoid muscle are suspended by the stylopharyngeus muscle, which are suspended in the air. If you have a problem with moving the cricothyroid articulation, you will notice it is hard to let out a high-pitched voice and that the hyoid bone will not move or shift well. The hyoid bone must shift well to make the space of the pharyngeal cavity bigger, therefor an echo effect can be produced as well as enhanced.
A vocal cord nodule refers to the vocal fold having a small calculus/mass/growth (primarily benign) which causes pain, cracking and/or a hoarse voice. Also popularly known as “singer’s” nodules.
Treatment of a vocal cord nodule is as follows 1.complete rest of the voice 2.using steroids 3.surgery, removal/extraction of the nodule. The method of treatment for each individual will depend on the degree of the nodule, which is determined by the hospital or treatment center.
The hospital mainly treats after having been diagnosed with a vocal cord nodule, but you can prevent acquiring vocal cord nodules in advance.
I’ve investigated thousands of people who have vocal cord nodules. As a result, I can attest that 99% of the people I have examined have muscle hypertonia. Which is classified as having more than 30 Tones of hardness in the musculus extrinsic laryngis.
You will never get a vocal cord nodule after singing or shouting for a long time. Preventative measures can be taken which are: getting flexibility of the musculus extrinsic laryngis, improving the blood circulation of the superior laryngeal artery and vocalizing without straining muscles.
