Too often, acoustics are treated as an afterthought - addressed only after a venue is built and problems become obvious. But just as lighting and HVAC are integrated into the design from the start, so should acoustics. Active Acoustic Systems (AAS) make it possible to deliver flexible, high-performance acoustics from day one. Here’s how early integration can transform both the design process and the long-term success of a venue.
Why Acoustics Are Often Overlooked
In many projects, budget and design energy are directed toward the visible: architecture, seating, finishes, and stage technology. Acoustics remain invisible until the first rehearsal or event reveals issues like poor speech clarity, excessive flutter echoes, or a reverberation time unsuited to the program. By then, fixes are costly and usually limited to passive treatment.
In most cases, some attention is paid to acoustics during the design stage, but it is often too limited. A few diffusive panels may be included as aesthetic features, yet in practice the hall still suffers from flutter echoes and insufficient diffusion. The result is a space with a few “sweet spots,” while large areas of the audience experience compromised sound quality or even very poor listening conditions.
Another common issue is that a hall is designed with a single, fixed reverberation time that ends up pleasing no one.
- For ensembles or unamplified music, it is too short, leaving performances flat and lacking warmth.
- For amplified productions, it is too long, creating a blurry mix with “too much room.”
The result is a compromise space that underdelivers for both purposes. Active Acoustics prevents this by making reverberation flexible, so the hall can adapt to every type of program.
The Advantage of Active Acoustics
AAS provides a way to design flexibility into the building itself:
- Variable Reverberation: Adjust the RT electronically to suit different events - from spoken word to symphony orchestra.
- Balanced Diffusion: Use loudspeakers and microphones to create even energy distribution across the hall, reducing flutter echoes and dead spots.
- Support for Multiple Formats: Combine AAS with VAS, SPA (Spatial Audio), and Surround to enable speech, classical concerts, amplified shows, and immersive performances in the same venue.
How to Integrate AAS During Design
- Acoustic Planning in the Concept Phase
Just as you plan for lighting grids and rigging, identify early where microphones and loudspeakers will be mounted. This avoids clashes with architecture later. - Collaboration with Architects and Consultants
Architectural elements such as balcony fronts, side walls, and ceiling grids all influence the acoustic field. When AAS is considered early, the system can complement the natural acoustics rather than fight against them. - Infrastructure for the Future
Running sufficient cabling, providing technical spaces for processors, and ensuring rigging points for speakers ensures the venue is “future-proof.” Even if the full system is not installed at opening, the infrastructure can support upgrades later.
Examples from SIAP Projects
- KIPO Cultural Hall (Norway): By integrating AAS during the design phase, the hall was equipped with variable reverberation tailored to both speech and music, resulting in a venue that seamlessly supports chamber concerts as well as amplified events without compromise.
- Gapyeong Cultural Center (Korea): Early coordination ensured that microphones and loudspeakers could be placed in optimal positions, which results in a system that is both acoustically effective and architecturally unobtrusive, delivering flexible reverberation control without compromising the visual design of the hall.
- Singapore Science Center (concept design): Planned from the outset with AAS, Spatial Audio, and Surround in mind, the concept demonstrates how a multi-purpose venue can deliver educational clarity for presentations while transforming into a fully immersive sound environment for exhibitions.
The Payoff for Owners and Users
Integrating active acoustics at the design stage saves money in the long term, avoids retrofitting headaches, and creates a venue that remains relevant for decades. Venues with flexible acoustics attract more bookings, satisfy a wider range of users, and deliver better audience experiences.
Conclusion
Active Acoustics is not just an add-on - it is a design principle. By considering AAS alongside lighting, seating, and architecture, venues can be built to serve every artistic and functional demand. Early planning ensures spaces that sound as good as they look.stic and functional demand. Early planning ensures spaces that sound as good as they look.
