Under the influence of environmental noise, the propagation distance of the sound source is reduced. Therefore, in addition to conventional concert halls, opera houses, and theaters, some public event venues can use electro-acoustic technology for sound reinforcement, amplify the sound source signal, increase the sound pressure in the listening area, and ensure that each listener can receive appropriate sound. pressure level. In recent years, with the rapid development of electronic technology and electro-acoustic technology, the sound quality of the acoustic sound reinforcement system has been greatly improved, which can meet the continuous improvement of people's requirements for sound quality.

Amplified sound system is also called professional sound system. There is a common misconception that a sound reinforcement system is a very simple matter of connecting microphones (and other sound sources), mixers, amplifiers, and speakers to create a sound reinforcement project. This kind of understanding has led many owners to invest a lot of money, but the available sound reinforcement effect is vague, the interference of feedback whistling makes the sound unable to be loud, and the sound quality becomes tasteless when the music is played back.

Sound reinforcement system is a systematic project, which involves electronic technology, electro-acoustic technology, sound technology and acoustic art, etc. It also needs to be integrated with video system (multimedia projection and camera system), stage or dance hall lighting system, fire broadcast System, paging broadcast system and security system and other subsystems are closely coordinated and coordinated. The sound quality of the sound reinforcement system is not only related to the comprehensive performance of the electroacoustic system, but also related to the sound propagation environment - the use of architectural acoustics and on-site tuning. The use function and sound effect of the sound reinforcement system require the best cooperation of correct and reasonable electro-acoustic system design and debugging, good sound transmission conditions, and correct on-site tuning technology. The electronic sound system is like a car on the road, the audio equipment is like the road, and the tuner is like the driver of the car. The performance of a car is a necessary condition for safe and fast driving. The quality of the highway road surface is an important basis for realizing a balanced and fast driving of the vehicle. The driving skills and experience of the driver are the basic guarantee for driving safety. Third, they complement each other and are indispensable.

As a system problem, the sound reinforcement system must comprehensively consider the above problems in the system design. Through careful system design, meticulous system debugging, good sound construction conditions, and on the basis of selecting electro-acoustic equipment with good performance, a pleasant and natural sound effect can be achieved.
