Overview
Modern libraries often feature open architectural designs, including multi-level atriums and double-height spaces. While these layouts create a spacious and welcoming environment, they also present challenges when different floors have different audio requirements.
The Library of Aba Teachers University in Sichuan, China, faced exactly this challenge. The open atrium connects the first and second floors without physical barriers. The first floor requires audio playback for visitor guidance, announcements, and activities, while the second floor serves as a quiet reading and study area.
Conventional loudspeakers distribute sound in multiple directions, allowing audio to travel through the open atrium and disturb readers on the upper floor. Lowering the volume, however, makes it difficult for visitors on the first floor to hear clearly.
To address this challenge, the library selected Audfly directional audio technology to create focused listening zones on the first floor while preserving a quiet environment on the second floor.
The Challenge
How to deliver clear audio on one floor without disturbing another?
In an open atrium, sound from conventional speakers can travel freely between floors. This makes it difficult to balance the need for clear announcements in public areas with the quiet atmosphere required in reading and study spaces.
The library needed an audio solution that could:
-
Deliver clear voice announcements and audio guidance on the first floor
-
Prevent unnecessary sound spill into the second-floor reading area
-
Create distinct audio zones without physical partitions
-
Integrate into the existing architectural structure with minimal modification
The Solution
To meet these requirements, the library deployed Audfly directional audio speakers, using focused sound technology to control where audio is delivered.
Unlike conventional loudspeakers that spread sound in multiple directions, directional speakers project audio toward a specific target area, much like a flashlight directs a beam of light. This helps concentrate sound within the intended listening zone while significantly reducing sound outside the target area.
Multiple Audfly Model B directional speakers were strategically installed along the surrounding beams of the first-floor atrium, directing sound downward into the designated listening area.
This installation approach allowed the library to establish a focused audio zone on the first floor without major modifications to the existing interior structure or occupying valuable floor and desktop space. Installation and commissioning involved standard mounting, speaker orientation, and volume adjustment.
Once deployed, the system delivered clear audio within the designated listening area while minimizing sound spill into surrounding spaces.
The Results
The installation successfully addressed the library's challenge of delivering audio across an open multi-level space while maintaining a quiet reading environment.
Key benefits included:
-
Focused Audio Coverage: Clear voice guidance and announcements within the designated first-floor listening area.
-
Reduced Sound Spill: Audio levels decrease significantly outside the intended listening zone.
-
Quiet Upper-Floor Environment: The second-floor reading area remains undisturbed by routine audio playback on the first floor.
-
Flexible Audio Zoning: Different floors can accommodate different acoustic requirements within the same open space.
-
Easy Integration: Installation along existing structural beams without major architectural modifications.
By using directional audio technology, the library successfully created two distinct acoustic environments within one connected architectural space: an active audio zone on the first floor and a quiet reading zone on the second floor.
Global Applications of Audfly Directional Audio
Beyond this university library project, Audfly directional audio solutions have been deployed in a wide range of public and commercial environments worldwide.
At Expo 2025 Osaka, Japan, Audfly's directional audio speaker series was deployed across multiple exhibition areas, including landmark pavilion zones, Future Life experiences, children's interactive areas, and technology-art exhibition spaces, helping create focused and immersive audio experiences for international visitors.
Other applications include the Nintendo Museum in Japan, Incheon subway stations in South Korea, a train model museum in the United States, and self-service kiosks in Vietnam.
These projects demonstrate the versatility of Audfly directional audio technology across different environments, from cultural attractions and museums to public transportation and interactive information systems.
Products Used
Audfly Directional Audio Speaker Model B features a split-type design with an external amplifier, offering flexible installation and reliable audio performance. Its directional sound technology delivers focused audio within designated listening areas while minimizing sound spill into surrounding spaces, making it suitable for libraries, museums, exhibition halls, and other shared environments.
Conclusion
Open architectural spaces do not have to compromise between clear audio delivery and a quiet environment.
The Aba Teachers University Library project demonstrates how Audfly directional audio technology can create floor-by-floor audio zoning without physical partitions. By directing sound precisely where it is needed, libraries and other multi-level public spaces can provide useful audio information while preserving comfortable and undisturbed areas for reading, working, and learning.
