Practice and Exploration on the Application of Sound Reinforcement Technology in Outdoor Chorus

This paper discusses the application practice and challenges of sound reinforcement technology in outdoor chorus. Outdoor chorus faces complex acoustic environment, changeable meteorological conditions and background noise interference. Sound reinforcement technology can effectively compensate the attenuation of acoustic energy, improve sound clarity and layering through acoustic-electrical conversion, signal processing and electroacoustic reduction. This paper analyzes the selection and configuration of audio equipment in detail, including the reasonable layout and debugging of speakers, microphones and mixing consoles, and emphasizes the environmental adaptability and stability of the equipment. In addition, the paper also introduces the development trend of modern sound reinforcement technology, such as intelligent regulation, digital processing and network control, which improve the accuracy and adaptability of the system. Through the case of the Chorus of Nanchong Film Industry Vocational College, this paper shows how to apply sound reinforcement technology in actual performances to overcome environmental challenges and achieve high-quality sound effects. It is concluded that sound reinforcement technology is not only a technical operation, but also an important part of artistic expression. In the future, with the progress of technology, it will provide better technical support for outdoor chorus.
