Understanding the Acoustic Challenge in Airport Holdrooms
Airport holdrooms are dynamic environments where passengers wait, work, and relax against a backdrop of constant activity. The acoustic environment is particularly challenging due to the proximity of jet bridges, where aircraft auxiliary power units, ground support equipment, and rolling luggage create intermittent yet intense noise. For architects and interior designers planning flexible spaces, the integration of movable partitions offers a solution for reconfiguring holdrooms to accommodate varying flight schedules and passenger flows. However, the success of such partitions in controlling sound depends heavily on airport holdroom partition seal planning—a critical consideration that is often underestimated.
When a movable partition divides a holdroom, its acoustic performance is not solely determined by the panel itself. Sound can travel through gaps, around edges, and via structural connections—collectively known as flanking paths. In an airport environment, jet bridge noise can enter the holdroom through these paths, compromising the intended acoustic separation. Therefore, careful planning of seals, junctions, and interfaces is essential to achieve the desired acoustic environment.
The Role of Seals in Acoustic Partition Performance
Seals are the components that close the gaps between panels, and between panels and adjacent surfaces such as floors, ceilings, and walls. Their primary function is to block airborne sound transmission. In any movable partition system, the effectiveness of seals directly influences the overall sound insulation. For airport holdrooms, where noise from jet bridges can be broadband and intermittent, robust sealing is vital.
It is important to understand that acoustic performance is not measured simply by a single number. The Sound Transmission Class (STC) and Weighted Sound Reduction Index (Rw) are ratings that describe a partition’s ability to reduce sound transmission across a range of frequencies. These ratings are determined under laboratory conditions with specific test setups. In real-world applications, the actual performance can differ due to installation quality, flanking paths, and the presence of gaps. Therefore, relying solely on a high STC/Rw rating without addressing seal planning can lead to disappointing results.

Jet Bridge Noise Paths: A Unique Challenge
Jet bridges are the enclosed walkways that connect the terminal to an aircraft. They are sources of continuous noise from aircraft systems, ground power units, and air conditioning units. This noise can propagate into holdrooms through various paths:
- Direct transmission: Through walls and windows adjacent to the jet bridge.
- Flanking via structure: Through the building frame, floors, and ceilings, which can transmit vibrations.
- Gaps and openings: Around doors, service penetrations, and partition edges.
Movable partitions, when used to divide a holdroom, can inadvertently create new flanking paths if not properly sealed. For example, if a partition is installed with a bottom gap that is not sealed, noise can travel underneath. Similarly, gaps at the top or sides can allow sound to bypass the partition. Therefore, airport holdroom partition seal planning must consider all potential paths, including those specific to jet bridge noise.
Planning Seals for Straight, Turning, and Stacking Routes
Movable partitions are designed to operate along specific routes: straight runs, turning sections, and stacking areas where panels are parked when not in use. Each of these configurations presents unique sealing challenges.
Straight Runs
In a straight run, panels align linearly to form a continuous barrier. Seals between panels must be designed to compress and provide an airtight closure when the partition is deployed. The type of seal used—whether a compression seal or an automatic drop seal—affects the ease of operation and the acoustic integrity. For airport holdrooms, where partitions may be moved frequently, the seals must be durable and maintain their performance over many cycles.
Turning Sections
When a partition must turn a corner, the panels pivot on a track system. At these turning points, the seals must accommodate the change in direction without leaving gaps. This requires careful detailing to ensure that the seal continues to function effectively at the joint. In airport environments, turning sections are common to navigate around columns or to create L-shaped divisions.
Stacking Areas
When not in use, panels are stacked at a designated parking area. The seals at this location are not active, but the design must ensure that when panels are deployed, they align correctly to engage the seals. Stacking areas also need to be planned to minimize noise transmission when the partition is open, as the stacked panels can act as a partial barrier.
Finish Options and Their Impact on Seal Integration
EBUNGE movable partitions offer a variety of finish options, including laminate, melamine, fabric, leather, glass, and other approved surfaces. The choice of finish affects not only aesthetics but also the integration of seals. For instance, fabric finishes may require seals that are less visible, while glass panels may need seals that accommodate the rigidity of the glass. In airport holdrooms, where visual appeal and acoustic performance are both important, selecting the right finish and seal combination is a collaborative decision between the design team and the partition provider.
It is essential to discuss project-specific requirements with the manufacturer to ensure that the chosen finish does not compromise the sealing effectiveness. For example, a fabric-wrapped panel might have slightly different edge details compared to a laminate panel, which could affect the seal profile.
Pass Doors and Their Sealing Considerations
Many movable partitions include pass doors to allow pedestrian access without opening the entire partition. These doors are convenient in holdrooms, allowing passengers and staff to move between areas. However, pass doors introduce additional sealing challenges. The door leaf must be sealed around its perimeter, and the door frame must be integrated with the partition panels to minimize sound leakage.
Check the route, supports and clearances on coordinated drawings.
When planning a pass door, it is important to consider the swing direction, the type of gasketing, and the latching mechanism. In an airport environment, where doors may be used frequently, the seals must withstand wear and tear. EBUNGE can discuss pass door requirements as part of the project documentation, ensuring that the door’s acoustic performance is aligned with the overall partition.
Flanking Paths and Structural Connections
Even with perfectly sealed panels, sound can bypass the partition through structural connections. For example, if the partition is attached to a ceiling that is not acoustically isolated, vibrations can travel through the ceiling and radiate sound on the other side. Similarly, if the floor is a floating slab, the partition’s bottom seal may not be effective if the floor is not continuous.
In airport holdrooms, the building structure is often massive and may have expansion joints or service penetrations. These elements can act as flanking paths. Therefore, airport holdroom partition seal planning must include an assessment of the surrounding structure. It is recommended to work with an acoustic consultant to identify potential flanking paths and to design appropriate mitigation measures, such as adding mass to adjacent walls or using resilient seals.
Project Documentation and Coordination
Effective seal planning requires thorough documentation and coordination among all parties involved. This includes architectural drawings, specifications, and shop drawings that detail the partition layout, seal locations, and integration with other building elements. EBUNGE emphasizes the importance of project documentation to ensure that the partition system meets the project’s acoustic and functional requirements.
During the planning phase, it is crucial to review the layout, including straight, turning, and stacking routes, to confirm that the partition will operate as intended and that seals will be effective. This review should also consider the location of jet bridges and potential noise sources. By discussing these factors with the partition provider, you can develop a solution that addresses the unique challenges of the airport environment.
FAQ: Airport Holdroom Partition Sealing
