Study On The Sound Expression Of The Documentary About The Hearing-impaired

Documentary is a means to record and reflect the reality.It takes the content of real life as the original material and objectively and truly records the social life of human beings.Documentary consists of picture and sound,both of which serve for the authenticity of documentary.With the continuous development of the concept of documentary creation,sound,as an important creative element,plays a pivotal role in documentary creation.From the perspective of the development process of documentaries,their creative mode is also changing constantly,and the intervention role of sound in documentaries is becoming more and more obvious.With its unique expression techniques and artistic appeal,sound plays a finishing point role in documentaries.An excellent documentary should not only record the change of times,but also focus on the majority of ordinary people.In China,the hearing-impaired population ranks the first of the five major groups of disabilities,and is facing the double pressure of survival and life.It is of great practical significance to pay attention to the hearing-impaired population.In my graduation work Silent Boxer,I made full use of the expression of sound to expand the content,improve the narrative and render the atmosphere.To show the real living conditions of the hearing-impaired.In this paper,the characteristics of sound in the documentary about hearing impairment,human voice,environmental acoustics,music and other aspects of the sound expression of the documentary about hearing impairment are discussed,and the problems encountered in the creation of sound and thinking are described.
