How does chest vibrate exactly? Please point with your fingers high

Thoracic resonance is often used more in the lower parts of the voice, and it is often used more in the lower vocal areas of each voice. In fact, in all vocal areas of each of our voices, there needs to be a thoracic resonance component, it is just a matter of proportion. Here's how to get thoracic resonance:

When vocalization, the throat is in a state of yawning, and the lower palate naturally droops, moving the reflection point of the sound wave from the hard palate to the back of the lower teeth, so that the sound wave causes more vibrations near the larynx and trachea, and continues to be transmitted to the chest farmer to cause resonance. In the practice of thoracic resonance, we must pay attention to relaxation, and do not overly pursue thoracic resonance and press the larynx, mistaking the thick guttural sound for thoracic resonance.

4. The best resonance practice is to use humming, that is, the often said "humming" to practice "humming", such as closing the mouth and yawning, the lips are slightly closed, the emptiness in the mouth is as empty as possible, the nasal and pharyngeal cavity is opened, leaving the passage of the breath as wide as possible, and then let the breath pass through these channels smoothly, along the pharyngeal wall of the oral cavity, the nasal cavity wall into the sphenoid sinus of the head peasant association, the feeling of the sphenoid sinus is the center of the eyebrows of our forehead. Feel the sound forward and upward, and feel the center of the eyebrows vibrate, resulting in a brighter and more concentrated "humming" sound. This "humming" eyebrow is the head cavity resonance we are looking for.

In order to organically combine the three resonance cavities and form the integrity of the singing resonance, three related vowel groups can also be selected for practice during training. The biggest advantage of this method is that the space is larger, and the sound can enter the various resonance cavities more smoothly.

When I speak, my chest doesn't vibrate, but my stomach moves...Why does the ribcage vibrate....Big gasp.

Count the numbers: Take a deep breath, use the strength of the waist and abdomen to hold, count from 1, count to 60. Counting should be even, rhythmic, and not stealing.

Soot blowing: Take a deep breath and blow forward like blowing dust off the table, at a slow and fast pace, to feel the power of the diaphragm.

Do more sit-ups to strengthen your waist and abdomen.

Skill. 1.Feel the resonance of the chest: open your mouth slightly, relax your larynx, close the glottis (vocal cords), and make a soft voice like a goldfish spitting bubbles, or hum low to feel the vibration of the chest.

2.Lower the position of the larynx: (ibid.); Relax the larynx.

3.Teething: The so-called teething is to open the upper and lower large teeth (molars).

Leave room for oral resonance and touch the position of the big tooth in front of the base of the ear with your hand to see if it is open. Then some vowel sounds like "a" are pronounced. Feel the change in your voice.

4.Raise your cheekbones: Smile and speak, the corners of your mouth tilt slightly upwards while you feel the wings of your nose open.

5.Very soft palate: yawn, by the way, a long whistle.

Thoracic resonance: refers to our entire lungs, also called basic resonance, that is, every note we make when we sing has its participation, we try to sing a note, put our hands on the chest, we will feel the vibration.

Singing Andy Lau's songs has a strong sense of resonance, try to sing it, you will feel the vibration of your chest, remember this feeling, practice more, and you will get used to using this kind of resonance.

It may be a resonance phenomenon caused by the same frequency.

It's like a washing machine that shakes violently at a certain frequency when it first turns up.

You can use the triode file of the multimeter to measure the magnification of the SMD triode, and then find the corresponding magnification of 9013 (triode) instead, and the magnification requirements are greater than or equal to the SMD triode.

It should be a resonance phenomenon, because the vibration source frequency is the same as the vibration frequency of the small square bar said by the landlord, resulting in the original small vibration energy is accumulated and increased.

Moreover, it is likely to be caused by **, in fact, we often encounter **, but most of the time**frequency is not within our perception range, and the amplitude is very small, so few people pay attention to it.

I myself once found at home that the glass on the coffee table suddenly and spontaneously whined and vibrate.

The occurrence of resonance phenomena has nothing to do with the distance of the hypocenter. It is only related to the frequency of the hypocenter. When the frequency of the source is the same as the natural frequency of the resonant object, a violent vibration phenomenon occurs.

The resonance can be a break in the cement bridge, and of course it can make the strip vibrate.

The number of degrees of freedom is calculated by looking at the number of nodes a, then the number of degrees of freedom b of each node, and finally the total number of degrees of freedom is a multiplied by b. The order and the total number of degrees of freedom of the structure are equal, and the first-order vibration refers to the order corresponding to the minimum frequency. Now let's take a closer look at the number of degrees of freedom for each node, and only the number of displacements that need to be considered for that node:

For example, if we consider five nodes in a building, if we consider the lateral and vertical displacements and add one rotational displacement to each node, that is, one node has three degrees of freedom, and the whole structure is 5 times 3 equals 15 degrees of freedom. These 15 degrees of freedom correspond to 15 mode shapes, and there are 15 order frequencies, which can be calculated, and these 15 frequencies are arranged from small to large, and the smallest one is called the first-order frequency, which corresponds to the first-order mode shapes, and so on.

The phenomenon of resonance is the phenomenon of resonance when one active vibrating body (the source of vibration) causes another object (passive vibrating body) to produce the same form of vibration. If the natural frequency of the vibrated body is very different from the existing frequency, it is a general resonance phenomenon, and if it is close, it is a special phenomenon called "resonance". There are resonance phenomena that we need, and there are resonance phenomena that we want to avoid.

Resonance phenomena aren't all bad.

This mainly depends on what your company's purpose is to do this vibration test, what is it to verify, and then choose the test conditions.

The so-called vibration measurement method should be based on the nature of the specific object to be measured, whether it is a rotating machine, a building, or even the human body, and the vibration test method should be selected according to the various types of objects to be measured.

Resonance is a term used in physics with a very high frequency, which refers to the situation in which a physical system vibrates at a greater amplitude than other frequencies at a specific frequency; These specific frequencies are called resonant frequencies. At resonant frequencies, small periodic vibrations can produce large vibrations because the system stores kinetic energy.

When the resistance is small, the resonant frequency is approximately equal to the natural frequency of the system, or the natural frequency, which is the frequency at which it oscillates freely. There are many places in nature that have resonance phenomena, such as: the acoustic resonance of musical instruments, the orbital resonance between some Jupiter-like moons of the solar system, the resonance of the basement membrane in the animal ear, the resonance of electrical circuits, etc.

Humans are also using or trying to avoid resonance phenomena in their technology.

Simple example: a person shakes a small tree, the effect is not obvious, more people shake it together, the principle is: most things are composed of molecules, each molecule has a natural frequency When a certain energy is close to their natural frequency, they will be easier to release energy, The effect is the amplification of the vibration effect, for example, it should be shaken 3cm, it may shake 30cm (may be a bit exaggerated) That's what it means.

Resonance refers to the situation in which a physical system vibrates at a greater amplitude than other frequencies at a specific frequency; These specific frequencies are called resonant frequencies. Simply put, the vibration of one object causes the vibration of other objects, and at the resonance frequency, a small periodic vibration can produce a large vibration, because the system stores kinetic energy. When the damping is small, the resonant frequency is approximately equal to the natural frequency of the system, or the natural frequency, which is the frequency at which it oscillates freely.
