From the sounds of nature to the sounds of social life, human beings can not leave the sound. However, in a long historical period, there is a lack of effective technical means to preserve sound. In the thousands of years before the advent of gramophones and records, although sound was constantly carried and conveyed civilization and life, its initial content could not be preserved, and many of the sounds recorded in historical documents were finally lost, which is a great regret of civilization.
