Design Requirements for Line Array Sound System in Gymnasium


In today's world, stadiums are no longer just places for sports competitions and training. They also host various art performances and large-scale events. Therefore, the design of the stadium sound system must cater to multiple needs. Among these, the line array sound system plays a crucial role.

Conditions for Designing a Stadium Line Array Sound System


Architectural Acoustics Design: Creating the Perfect Sound Field Environment


The acoustic design of a stadium is the foundation of the sound system design. This includes considering the volume, structure, and choice and arrangement of sound-absorbing materials in the stadium. The goal is to achieve appropriate reverberation time, uniform sound field distribution, avoid various acoustic defects, and ensure sufficient loudness, clarity, and uniformity of the sound environment under various usage scenarios.


Electro-acoustic Design: Achieving Precise Sound Effects


Electro-acoustic design is built on the foundation of architectural acoustics design. By selecting appropriate speakers, their arrangement, and the choice of sound equipment, the ideal sound effect is achieved. This specifically includes the following aspects:


System Design Requirements: including system equipment selection, configuration, and acoustic design of the control room.


Characteristics Parameters of the Sound Reinforcement System: According to the "Stadium Acoustic Design Measurement Specifications," the sound reinforcement system should include multiple subsystems for the audience area, competition field, athlete's rest area, and audience rest area, with independent control and switching functions.


Specific Requirements: Loudness in the audience area, coverage range of the speakers, clarity of the listening conditions, system stability, and power margin.


Advantages of the Line Array Sound System


Line array sound systems offer many advantages in stadium sound system design:


  • Wide Coverage: can cover the entire audience area and competition field, avoiding dead zones, and ensuring uniform sound field.

  • High Clarity: provides clear listening conditions with good directionality and sound fidelity.

  • High Stability: has sufficient stability and power margin to ensure the sound system's reliability and consistent performance.


According to the "Grade 1 Indicators for Hall Sound Reinforcement Systems," the stadium sound reinforcement system should meet a series of precise technical indicators, including maximum sound pressure level, transmission frequency characteristics, sound gain, sound field unevenness, and more. Meeting these indicator requirements is key to the design of a stadium sound system.


In the design of stadium sound systems, the selection and configuration of the line array sound system will directly affect the realization of the overall sound effect. Therefore, meticulous design and precise implementation are necessary to ensure that all activities in the stadium achieve an ideal sound experience.
