What are the main factors that determine the quality of a human voice

The sound quality of the human voice is roughly determined by three factors: first, the length of the vocal cords, width and narrowness, thickness and tightness, and so on and the quality and condition; Second, the height of the human body, fat and thin, strong and weak, resonate.

the size of the cavity, hard and soft, through the plug; Third, the depth of the breath, the amount, the urgency, the frequency and amplitude of the vocal cord vibration.

The control of changes, resonance sites and methods of various mediations. It is of great significance to learn and master the scientific method of using qi to make sounds in order to improve people's innate sound quality and enhance their ability to generate sound. People with good voice talent may also deteriorate if they do not pay attention to the scientific use of their voice; And people with poor voice talent can also get benign changes to a considerable extent after scientific cultivation and making up for the deficiencies with the right methods.

The treble, the strong tone, does not mean the beauty, the low tone is weak.

Nor does it mean incompetence. If the treble and strong sound are used well, they can have strong expressiveness, and if the bass and weak sounds are used well, they will also have strong expressiveness. The key is to have a pure timbre and a smooth resonance.

Under this important premise, the choice and change of strength and weakness are mainly determined by the needs of content expression, and are also subject to the voice conditions and abilities of the expressor himself. Only by expressing the content and emotions in a clear and layered way within your most comfortable vocal range and dynamics can you give people a sense of beauty, and your voice is not easy to go wrong. Create more conditions for laughter, ponder the characteristics of physical movement when laughing, especially focus on the state of hard stomach and effortless laryngeal muscles, so that you can save effort, find the fulcrum of breath, exercise muscle coordination, and gradually develop the habit of supporting vocalization with the breath of laughter and making vocalizations in the state and position of laughter 1.

The speed of the breathing airflow and the amount of airflow are the core of the power of human voice. If you want to make sound with high efficiency and low energy consumption, you must use gas scientifically. The breath is concentrated, a little elastic, the force, the coherent flow of the line, and the restraint and erection of the tube, and the sound is naturally easy to achieve both saving breath and unity.

First, the effect of translucent and far-reaching.

I think the main factors that determine the quality of sound in a life are the thickness of the vocal cords and the width of the vocal range.

The factor that determines the high and low of the sound is the frequency. The frequency of the vibration determines the pitch of the sound, the fast vibration, that is, the frequency is high, the pitch is high, and the vibration is slow, that is, the frequency is low, and the pitch is low. The amplitude determines the magnitude of the sound, and the amplitude is large, i.e., the vibration is loud.

The frequency of the sound is called the pitch, and the amplitude is the loudness of the sound, that is, the magnitude of the sound, which determines the amount of energy carried by the sound wave.

The pitch is high or low related to the following factors:

1. The material of the string, the quality of a single wire, the number of each string, the quality, length and tightness of the strand.

2. The structure and material of the resonance box.

The frequency of the vibration determines the pitch of the sound, the fast vibration, that is, the frequency is high, the pitch is high, and the vibration is slow, that is, the frequency is low, and the pitch is low. The amplitude determines the magnitude of the sound, and the amplitude is large, i.e., the vibration is loud.

1. The pitch is related to the structure of the sound emitter, because the structure of the sound emitter affects the frequency of the sound. In general, the pitch of a low-frequency pure tone below 2000 Hz decreases with increasing loudness, and the pitch of a high-frequency pure tone above 3000 Hz rises with increasing loudness.

2. Pitch is also related to the length of time the sound lasts. Very short (millisecond or less) pure tones, with only a "click" like a blow or a snap of the fingers can be heard, and no tone can be felt. The duration has been increased from 10 ms to 50 ms, and it sounds like the pitch is changing continuously from low to high.

Beyond 50 milliseconds, the tone is stable.

Human voices are different, and the size of the throat should determine the volume and timbre of the voice. Sometimes you tighten your throat and the sound you come out of is different.

The size of the voice is related to the person's lung capacity, and if the voice is small and weak, the body may not be very good, and the voice is strong, which shows that the lung capacity is good. The timbre of the voice is related to the condition of each person's vocal cords, the child's voice is more pure and beautiful, and when the vocal cords change when they grow up, the timbre of the voice will also change.

The key is the Adam's apple of the throat, the size of the Adam's apple, the width and thickness of the Adam's apple determine the size and timbre of a person's voice, whether the voice is good, and whether it is pleasant.

Probably the vocal cords of the human body determine the volume and timbre of the voice, and the vocal cords of each person's throat part are different, so the voice is also different, which is innate.

The characteristics of a sound can be described by three elements, namely loudness, pitch, and timbre.

1. Loudness: The subjective perception of the human ear about the strength of the sound is called loudness. Loudness is related to the amplitude of the sonic vibration.

2. Tone: The human ear's perception of the height of the sound is called blind Zheng tone, and the tone is mainly related to the frequency of sound waves.

3. Timbre: Timbre is the reason why people distinguish two voices with the same loudness and the same tone is the comprehensive response of the human ear to sound waves of various frequencies and intensities, and the timbre is related to the vibration waveform of sound waves and the spectral structure of sound.

1.The characteristics of sound are related to the following factors: loudness, which is the subjective perception of the sound, commonly known as volume, is determined by the amplitude, the greater the amplitude, the louder, the unit is decibels.

2.Pitch, that is, the high and low level of the sound, is divided into high and low tones, which is determined by frequency, the higher the frequency, the higher the pitch, and the frequency unit is hertz.

3.Timbre, i.e., the properties of sound, are determined by the material and structure of the sound-emitting object itself.

The pitch of the sound is mainly determined by the frequency of the sound, and it is also related to the intensity of the sound, indicating the degree to which the human hearing can distinguish the tone of a sound. The pitch of the sound is determined by the vibrational frequency of the emitter, which is an object that is capable of producing sound itself. The vocal parts of different vocal bodies are generally different.

For example, the vibrating vocal cords, the vibrating tuning fork, the beating drum, etc. are all vocal bodies.

Sound is produced by the vibration of an object, and all sound-emitting objects are vibrating, note: unlike the sound source, the sound source is the object that is making sound, and the sound emitter is an object that can make sound, and the junior high school physics textbook stipulates that sound is produced by the vibration of the object. Everything that is making sound is vibrating, the vibration stops, and the sound stops.
