The multi-channel surround system used for multimedia teaching can bring more powerful auditory effects to the audience, and can fully mobilize students’ interest and enthusiasm in learning. Such as music arrangement, Yunnan musical instruments, the sound characteristics of national music and national musical instruments, and the sound processing knowledge of music processing. You can quickly master basic music arrangement, the sound characteristics of musical instruments, and the knowledge of mixing and processing music. Achieve better teaching results. Most multimedia devices on the market, with the music and sound effects, a high compression mono or stereo transmission. This mono or stereo transmission with a high compression ratio is very low quality. Since audio is far less powerful than visual impact, and the capacity of the disc used to store audio is small, people tend to focus on visual information processing, but ignore the importance of audio. Multi-channel surround sound technology has received more and more attention in the teaching practice of film and television colleges, but it is also affected by various factors such as venue facilities. This has caused bottlenecks in teaching in this field and has greatly affected the teaching effect. This paper designs and constructs a mobile multi-channel surround sound teaching system from a practical perspective. As part of a multimedia teaching device, try to use the best digital surround sound system for today’s audio reproduction. The feasibility of entering the digital surround sound system into the multimedia teaching classroom is analyzed. Better promote students’ correct understanding of audio and use modern high-tech digital technology to spread real art.

Recently, with the development of video technology, 3-D sound field reproduction systems that can provide a high presence have attracted attention. Conventional systems with electro-dynamic loudspeakers have a problem that the sound image lacks sharpness when constructing a narrow sound image. To solve this problem, we utilize a parametric array loudspeaker which has sharp directivity by the straightness of ultrasounds. Parametric array loudspeakers can produce sharper sound images due to the sharper directivity and lower reverberation compared with electro-dynamic loudspeakers. However, it is difficult to represent reverberation by parametric array loudspeakers. In this paper, we propose a method for 3-D sound field reproduction to achieve both the sharp images and reverberation presence by combing parametric array loudspeakers and electro-dynamic loudspeakers in surround sound system. In the proposed method, sharp sound images are rendered by parametric array loudspeakers and the reverberation presence is provided by electro-dynamic loudspeakers, emitting reverberation signals synthesized with a reverberation control filter. The reverberation control filter is adaptively designed to reproduce the reverberation time and the direct-to-reverberation ratio of the target sound field in other environments. The experimental results show that the proposed method can achieve the reproducing the sharp sound image with some reverberation presence.

Multi-channel dynamic matrix sound system (DMS) is a multi-channel input and output sound system which is based on source synthesis and Huygens' principle. The sound sources are recorded by microphone array and multi-channel independent recording, instead of the field. This paper describes the results of the subjective evaluation experiments between DMS and conventional stereo system by the semantic differential (SD) method. Five parts of the audio materials and a training material, including the human voice, music, sound effects, were used as the stimuli. All of the stimuli were recorded by the DMS and conventional stereo system respectively. The results proof that the effectiveness of DMS, which has a higher level of sound quality and can give the audience the experience of dynamic subjective feelings compared with conventional stereo system. Furthermore, sound designers must carefully consider the influence of gender, age, preferences on the hearing impression.
