Film and television works are composed of images and sounds, and the role of sound in film and television creation can not be ignored. Sound can add emotion, atmosphere and rhythm to film and television works, and make the audience more immersed in the world of movies. Sound can add emotion to movies. Music, dubbing and sound effects in the film can all express the emotion and inner world of the character through sound.

Film and television sound is another basic element in film and television art besides images, which makes film and television art a relatively complete audio-visual art and is close to people's real feelings.
It makes film and television art a relatively complete audio-visual art and an audio-visual art close to people's real feelings. The nature of sound The characteristics of sound are tone, volume, length, timbre and speed. Sound waves travel at a fixed period, and the number of periods per second is called the frequency of sound waves. The frequency is in hertz.
The frequency range of human voice is between 200 Hz for bass and 3000 Hz for soprano.
For example, in China's film Farewell My Concubine, there are obvious differences in the colors of pebbles, beans, small buildings, butterfly dresses and chrysanthemums. It is also important to know the tone of the characters to choose the model of recording microphone and tape recorder. Sound waves with different amplitudes produce different volumes. The amplitude increases, the sound increases, and the volume increases.
The volume is measured in decibels. The volume of different people at different distances is different in different environments and different moods. In general film and television works, the volume of characters is high when they are excited, normal when they are calm and low when they are depressed. But there are exceptions
V.I. pudovkin's "Deserter" was played at a high volume even when the workers' demonstration was badly damaged. The softness, clarity, * * aria and fullness of the voice determine the quality of the timbre.
The timbre is mainly determined by the number of homophones and the relative strength of each homophone. Piano and organ play the same tune with the same volume, and people can easily distinguish it because of their different timbres. The duration of sound is the length of sound. It can be divided into three stages: initial stage, continuous stage and attenuation stage.
The phonetic sound length is related to language and characters. In Mandarin with dialect accent, the sound length of Southwest Mandarin is longer than that of Shanghai Mandarin. In TV programs, especially funny entertainment programs, using Putonghua with different sound lengths will often get unexpected results. In terms of personality, people who are impatient have short pronunciations, while those who are chronic have slightly longer pronunciations.
The speed of sound is 340 meters per second. The slow speed of sound has a certain influence on film and television production, which will cause the problem of hearing error. For example, when recording with two microphones, the recorded sound may be inconsistent. But the slow speed of sound is also useful in some places, such as creating a sense of space. The composition of sound in film and television art includes human voice, music and sound.
From the functional point of view, the three are not clearly defined. For example, a cry or the buzz of the masses is not only a human voice, but also an environmental voice; It is music and a simulation of natural sound to express the bird's scream with the sound from the high-pitched area of the violin. Judging from a complete work, all kinds of voices work together to complete the overall acoustic effect of the work.
Vocal voice refers to all kinds of sounds that people make when exchanging information, expressing thoughts and feelings, such as words, singing, sighing and laughing. There are three forms of expression: dialogue, monologue and narration, and the latter two are collectively called voiceover.
In addition to explaining, promoting plot and expressing logical thinking, human voice is expressive because of its timbre, timbre, strength and rhythm, and can express psychological contents such as mood, character and temperament.
Music refers to music transformed from pure music form and specially created and arranged for film and television works. Film and television music has the characteristics of general music art and its own independent personality. Its functional form and expression have changed.
Sound is the general name of all sounds except human voice and music in a work. According to different sources, acoustics can be divided into action acoustics issued by human or animal movements, natural acoustics issued by natural phenomena such as wind, rain and thunder, background acoustics issued by mass actors, mechanical acoustics issued by mechanical equipment, gun acoustics, artificial unreal special acoustics and so on.
Sound can produce a sense of scene and reality, time and times, space and orientation, movement and speed, emotion and atmosphere, metaphor and symbol.
