Professional Sound System Solution for Large Outdoor Stadiums

2023 Guangzhou DSPPA Audio Co., Ltd.
Design Objective

The sound system of the sports field is primarily a real-time amplification of the speaker’s voice to the listener, and the speaker and listener are usually in the same acoustic environment. A successful sound reinforcement system must be loud enough (sufficient sound gain) and clear enough (low percentage of speech consonant articulation loss), and be able to evenly cover the audience while not covering areas where there is no audience.

● This system can not only meet the national acoustic standards for stadiums but meet the requirements for live broadcasts and rebroadcasts of various sports events, featuring intelligence, digitization and scalability.

● DANTE audio processor solves the problem of long-distance transmission and wiring while reducing the sound delay. As the phased array speaker has high sensitivity, the sound in the whole sound field is clear and bright. On the premise of meeting the requirements of sound pressure level, it enjoys a wide horizontal coverage area, small vertical projection angle and concentrated distribution of sound field, ensuring the intelligibility of the projected sound field.

● To ensure normal use in various functions and situations, the system can be manually intervened and adjusted at any time, so that the sound engineer can adjust and control the system as needed at any time.


Stadium Description


The stadium is mainly used for sports games and rallies, and a professional sound system is required for the opening ceremony, mass games, live commentary of the football match, etc. While considering the functional requirements of various sports competitions in the future, theatrical performances should also be taken into account. The professional conference call speaker system plays an important role in the weak current system of the football field.


In order to allow the audience to get the information sent by the referee during the game, the system is required to have a better sound transmission gain. Generally, the auditorium around the stadium is high, while the competition terrain is low. Speakers often are suspended under the canopy for zone sound reinforcement, as the directional characteristics of the speaker system are utilized to ensure that the auditorium has sufficient sound pressure level and good speech intelligibility. In order to mask the impact of noise, the sound pressure is generally required to be around 100 dB.


Design Approach


According to the outdoor arrangement and the function positioning, we adopt decentralized sound reinforcement to meet the uniformity of sound pressure in the sound field of the venue. Under the condition of meeting the sound pressure requirements, combined with the suggestion of use, the outdoor column speaker we designed is used for playground performance at ordinary times.


According to the national acoustic characteristic index standard for outdoor sound reinforcement system design, the maximum sound pressure level in the open field quasi-peak state: 125-4000Hz, with an average greater than or equal to 98dB. However, the audio sound reinforcement system we designed meets and exceeds the national standard, which reflects the superior performance of the system. The sound effect of the professional sound system meets the first-level standard of language and music in the GYJ125 Acoustic Characteristic Index for Outdoor Sound Reinforcement System Design, achieving clear language, no distortion, sufficient sound pressure margin, and uniform sound field distribution.


Professional Sound System - Configuration Solution for Outdoor Stadiums


Pickup Part: We choose true diversity wireless handheld microphone and wired condenser microphone to ensure the broadcast of the event and the speech of the leaders. Meanwhile, we adopt an antenna amplification system to ensure that there will be no wireless signal loss or crosstalk.


Regulation and Control Part: We apply the digital mixing console, digital audio matrix and feedback suppressor to regulate and control the whole system. The digital mixing console is simple in interface display yet powerful in function and has various audio signal input and output interfaces to meet the connection of mobile sound reinforcement system, radio and television broadcast output, large screen system, recording and calling system, press release area and background broadcasting system. It allows the operator to quickly perform the mixing operation and can be extended for subsequent system expansion. The digital audio matrix has rich built-in peripheral modules, which can carry out various processing operations on the whole system, and supports DANTE transmission, thus eliminating the trouble of long-distance wiring, ensuring the signal-to-noise ratio and reducing the failure rate. The feedback suppressor greatly reduces the possibility of on-site sound howling, ensuring the operation of the entire system.


Sound Reinforcement Reduction System: We use highly directional dual 10” line array speakers for decentralized sound reinforcement. The line array speakers not only have a large sound pressure level but can be adjusted in the vertical angle according to the listening surface. Each group is also equipped with a single 18” subwoofer to compensate for the lower limit of low and medium frequency. The 400W constant resistance horn speaker is used to supplement the sound in the area that cannot be covered by line array speakers, and the monitor speaker is used to help the operator to better understand the state of the sound source.


System Protection: To ensure the safety and reliability of the system equipment in use, especially in case of accidents, it can protect the equipment from damage. It is mainly equipped with power sequence controllers.
