Considering the characteristics of architectural acoustics, the system designed and configured, the electroacoustic indicators meet the acoustic characteristics of the sound reinforcement, the language system and the music integrated system meet the national standards. The performance and quality of the sound system will directly affect your future use. We analyzed the structural characteristics and functions of the site and used the EASE3.0 computer audio system design software to complete it. Sound system design. When the sound system design scheme is initially formed, and the speaker brand and audio equipment are reasonably selected according to the actual situation, this is the core of the whole sound system, which determines the overall quality of the sound reinforcement system.

The purpose that the design needs to achieve

1. Public broadcasting system:

Organize and play the broadcast and background music. The radio room mainly includes FM receiving wireless signals. Tuning device for broadcast programs. Management computer central equipment such as microphones, sound reinforcement equipment, recording and broadcasting of music programs. Functional requirements: good sound quality, multiple ways of signal input and output channels, high performance and reliability. The background music is located in public areas such as walkways and lounges. The speaker is ceiling mounted. The background music is shared with the fire emergency broadcast speaker. When a fire occurs, the system controls the components such as the volume switch to cut the background music to the emergency broadcast.

2. Conference sound reinforcement system:

(1) Sports competitions, mass gatherings, and the functions of group gymnastics music accompaniment, and reserved large-scale cultural performances and relay interfaces;

(2) Reasonably arrange the speakers by combining the characteristics of the stadium building, so that each auditorium can ensure clear voice and beautiful sound quality;

(3) Set the microphone plug-in box on the podium, commentary seat, competition venue, etc. to provide enough microphone points to meet the needs of various competitions and gatherings;

(4) setting the function of issuing a notification from the sound reinforcement room;

(5) Notices may also be issued to the athletes, coaches and referee rooms by the check-in office;

(6) Using the plug-in control box set in the fire control room, you can switch the volume controller to send out the evacuation signal to the check-in office and the competition user, VIP lounge, private room, conference room, etc. separately or at the same time. The broadcast section is completed with settings).

Combine the above characteristics to summarize the necessary sound reinforcement requirements:

(1) There is enough loudness in the audience.

(2) The arrangement of the speakers should cover the entire auditorium and the competition venue. Try to make the sound field uniform and there should be no dead zones.

(3) Have clear hearing conditions, good sense of direction and fidelity of the program.

(4) The system should have sufficient stability and power headroom
