A Stadium’s Level Begins with Its Requirements

Why Sound Must Be Defined at the Concept Stage

A modern stadium stopped being “just for sports” a long time ago. Today it is a multi-purpose venue designed not only for international competitions, but also for concerts by global superstars, large-scale ceremonies, and public and cultural events that fill the stands.

That is why the decisions made at the earliest stage—when the venue concept is being defined—have a decisive impact on its future. At this point, the focus is not on specific hardware models, but on the level, standards, and operating logic of all key systems, including sound.

In practice, this is where the role of audio is most often underestimated—not because of a mistake or a lack of understanding, but because it is seen as equipment that can be chosen later. International practice shows that this approach inevitably leads to limitations that become obvious only after the stadium opens.

What makes a multi-purpose arena different from “just a stadium”

A stadium of international level today must perform confidently across very different scenarios:
During the day: a football match where speech intelligibility for announcements and synchronization with video are critical.
A week later: a top-tier concert where impact, SPL, accuracy, and scale matter.
Another day: a state event or ceremony with different requirements for control, zoning, and distribution.

If sound was not designed as infrastructure, the system starts “living on compromises.” It may be acceptable for one scenario but limiting for another. And that is exactly what most often leads to post-handover modifications, temporary fixes, and dissatisfaction among stakeholders once the venue is in operation.

Infrastructure is about level and predictability

Equipment can be replaced or upgraded.
Infrastructure defines the framework the venue will live within for decades.

When sound is treated as an infrastructure system, it is designed in parallel with architecture, structure, and engineering networks. The design accounts for bowl geometry, reflections, audience zoning, screen placement, evacuation logic, and control scenarios. The result is a system that becomes part of the stadium’s architecture—not an extra layer added on top.
This approach is what allows an arena to be ready for sports broadcasting and world-class concerts without having to “adapt” the space for every event.

What happens when sound remains “equipment”

If, at the requirements stage, sound is described only in general terms—without fixing target performance levels and use cases—the project becomes vulnerable. Later, during design and construction, this often allows decisions to be changed or simplified without formally violating the documentation.

At opening, the venue may comply with all regulations, but real operation reveals that the system is:

not flexible enough,
difficult to control,
limited for concert formats,
dependent on constant temporary solutions.

It’s important to emphasize: this is not someone’s fault. It’s the consequence of not locking sound in as a key infrastructure element at the requirements level.

International practice for multi-purpose arenas

In venues that host major sporting events and tours by global artists, sound is designed as a single long-term system. The emphasis is not on individual components, but on predictability, controllability, and the ability to support multiple event formats.

That is why international projects widely apply L-Acoustics-based solutions. These systems have evolved with a focus on scale, acoustic complexity, and the multi-use nature of arenas—where sound must work equally effectively for sport and for live music.

Combined with digital mixing platforms such as DiGiCo, this creates an audio environment that becomes part of the venue’s overall concept, not a separate technical solution for a specific event.

Why the requirements stage is critical

It is exactly at the stage when:

the venue concept is approved,
standards are defined,
performance expectations are set,

that you can implement an infrastructure approach to sound without the pressure of deadlines and budget. At this point it is easier to align the interests of the client, architects, consultants, and operations.

When sound is fixed as infrastructure, it stops being a constant compromise in later phases. This simplifies the work for designers, reduces risk for contractors, and ensures stable operation after opening.

What this gives the client and the city

For the client, this approach means:

readiness for international sporting events,
the ability to host concerts by world-class artists without limitations,
reduced risk of post-opening modifications,
long-term protection of the venue’s reputation.

Infrastructure sound is not about overengineering. It is about matching the level of the tasks modern stadiums are expected to handle.

Conclusion

When a stadium is treated as a multi-purpose, international-level arena, sound is no longer a question of choosing equipment. It becomes part of the infrastructure that defines what events the venue can host—and how it will perform under real operating conditions.

That is why sound decisions must be made at the stage of defining requirements and standards—when there is still an opportunity to set the right benchmark and secure a sustainable future for the venue, both as a sports facility and as a concert venue.
