专业音响工程是随着社会的发展，人们物质文化生活的不断提高，从而形成的对文艺演出、娱乐休闲形式的不断要求而逐渐发展起来的新兴行业。通常所谓的专业音响工程主要是包括专业舞台音响灯光系统、实用音响灯光视频系统、商业广播会议系统等在内的一种系统工。具体在工程技术上，它集建筑、电子、电工技术于一体，是包含了声学、光学、音频、视频等多项理论的一门综合性工程技术。它要求工程商根据用户不同的实际需要，认真研究，全面融入设计者的设计思想，精心设计和施工；同时还要得到建筑装饰、电力供应部门的密切配合才能完成。可见，专业音响工程的意义非常重要，相应地工程技术的重要性也显得十分突出。
With the development of society and the continuous improvement of people's material and cultural life, professional audio engineering is a new industry which has gradually developed with the continuous requirements of artistic performance, entertainment and leisure forms. Usually, the so-called professional audio engineering is a system engineering including professional stage sound and lighting system, practical audio lighting and video system, commercial broadcast and conference system, etc. In terms of engineering technology, it is a comprehensive engineering technology which includes acoustics, optics, audio frequency, video and so on. It requires engineers to study carefully according to the actual needs of different users, fully integrate into the designer's design ideas, carefully design and construction; at the same time, it can be completed with the close cooperation of building decoration and power supply departments. Therefore, the significance of professional audio engineering is very important, and the importance of engineering technology is also very prominent.
