In Chinese tradition, the palace merchant corner emblem feather has the theory of corresponding to the five organs. Each sound has a corresponding viscera, and the corresponding viscera can be adjusted through ** to regulate the health of the body. The uterine tone corresponds to the lungs, the Shang tone corresponds to the liver, the horn tone corresponds to the kidney, the Hui tone corresponds to the heart, and the feather tone corresponds to the spleen.
At first glance, it sounds a bit mysterious, but this can be preliminarily understood from the perspective of modern science.
The spring breeze is sultry, and the pneumatic mountain is cute.
The wind is big and small, the big one has twelve levels, the wind is fierce, and the sultry effect is different. **The wind generated is too strong, and it is not enjoyable to call it wind, so it is called a shock wave. The bullet pierces through the glass, and by shooting it slowly, the air flow in front of the bullet has broken the glass before it touches the glass.
The air is not empty, the air can flow, and the flow can be sultry and provocative, pushing the clouds and rolling the sand table.
Sound is the high-frequency back and forth movement of the air, and the person who hears the sound is the back and forth movement of the air on the eardrum. Knocking on a shrapnel will buzz, that is, the shrapnel vibrates back and forth, causing the air to flow back and forth at a high frequency, which is also called a sound wave, and the back and forth is a wave, and this wave has a chain reaction in the air and can spread out, just like throwing a stone in the water, causing a water wave, and the water wave will be transmitted, and the reason for sound propagation is almost the same.
The speed of the air coming and going in the sound wave is called audio, taking shrapnel as an example, the shrapnel shakes fast and the sound is sharper, and the pitch is higher in ** terms, such as C tone, which shakes 260 times per second, and D tone 293.
Audio is fast and slow, and sound waves also have a characteristic called wavelength, which can be interpreted as high and low as water waves, and the horizontal distance between the tip of the wave and the bottom of the wave is called wavelength.
People who play ** are generally aware of the fact that the sound resonance, such as the cabinet of the guitar, the drum body of the African drum, will amplify the sound effect. Resonance is the amplification of sound, and the amplification of sound is the superposition of sound.
Striking a drum produces air flow, and this flowing air acts on the drum body, causing the drum body to vibrate, and the vibration of the drum body has an effect on the air, and another sound comes out, and this sound is superimposed with the original sound of the drum surface, which is probably resonance.
The sound coming out of the drum surface has the main tone, and it will also mix the tones of various pitches, and the sound superposition and resonance effect will be produced in the drum body, but the resonance effect of different tones is different, some superposition is strengthening, and some are messy offset.
Let's take an example of swinging. A person is swinging, and the person pushing has a rhythm, find the right point, such as every time you give a little force at the highest point of the swing, the swing will swing higher and higher, if you can't find the right point to give force, it will destroy the swing amplitude.
Sound propagation is said to be so, when the sound air wave is transmitted to the drum body, the drum body will have a reaction force on the sound wave, this force is just at the sound wave and the peak or bottom of the wave, just like the key point of the swing, it is strengthened, and the sound of the drum body is also in tune, so the size of the drum cavity, and the rhythm and combination of the sound wave audio, is very important to the effect of resonance.
According to research data, the best results are achieved when the size of the closed cavity is a multiple of a quarter of the wavelength of the sound. Wavelength and audio are one-to-one.
If the resonance box on the ** body, the cavity and chamber of the five organs and six organs of the ** body, the size of the space, and the possibility of resonance with the fixed audio pitch exists, when the resonance resonance effect reaches a certain level, the possibility of having an effect on the viscera must exist.
This just means that the possibility of the correspondence between the five tones and the internal organs must exist, but the scientific nature of the specific correspondence and how the ancients knew and summarized it need to be further verified by the masters.
