When planning an airport holdroom, the airport holdroom partition seal jet bridge noise challenge requires careful attention. Jet bridge operations generate continuous and intermittent noise that can flank through partition perimeters if not properly addressed. For architects and facility planners, understanding how movable wall systems seal against such noise paths is essential. This article guides you through planning considerations, from layout to documentation, for holdroom partitions that must perform in demanding airport environments.
Understanding Jet Bridge Noise Paths
Jet bridges connect the terminal to aircraft, and they transmit noise from aircraft engines, ground support equipment, and passenger movement. This noise can enter holdrooms through various paths: gaps around partition edges, under doors, through service penetrations, and via structural vibrations. Effective acoustic separation requires addressing both direct and flanking paths.
Direct vs. Flanking Transmission
Direct transmission occurs through the partition panel itself. Flanking transmission happens around the panel—through perimeter seals, ceiling gaps, or adjacent construction. In airport settings, flanking paths are often the weakest link. A partition with excellent panel performance can still underperform if seals are poorly planned.
Typical Noise Sources Near Holdrooms
- Aircraft auxiliary power units (APUs)
- Ground power units and air conditioning carts
- Baggage tugs and belt loaders
- Jet bridge wheels and leveling systems
Role of Movable Wall Systems in Holdrooms
Movable walls offer flexibility to reconfigure holdroom spaces for different flight schedules or passenger flows. Unlike fixed walls, they can be moved to create larger or smaller zones. However, their movable nature introduces potential gaps that must be sealed effectively. EBUNGE movable wall panels are individually movable and suspended from a top track, crossing the opening without a floor track. This design allows for flexible layouts while minimizing floor obstructions.

Benefits of Top-Track Suspension
With no floor track, there is no floor channel to collect debris or create trip hazards. The panels hang from an overhead track, and the bottom can be sealed against the floor using drop seals or gaskets. This is particularly useful in airport terminals where floor cleanliness and safety are paramount.
Planning for Stacking Positions
When not in use, panels park at a planned stacking position. This stacking area must be designed to accommodate the panels without interfering with circulation or other functions. The layout should be reviewed to ensure straight, turning, and stacking routes are feasible within the holdroom geometry.
Sealing Strategies for Perimeter Gaps
Perimeter seals are critical to reduce noise leakage. The top of the partition, where it meets the ceiling, and the bottom, where it meets the floor, are primary leak points. Additionally, vertical joints between panels must be compressed to form a continuous barrier.
Top and Bottom Seals
Top seals typically consist of a gasket or brush that compresses against the ceiling track or a fixed header. Bottom seals often are automatic drop seals that lower when the panel is in position. These seals must be specified to match the floor surface and the expected deflection of the structure.
Vertical Joint Seals
Between adjacent panels, a compression mechanism pulls panels together, compressing a gasket. The effectiveness depends on the alignment of panels and the quality of the gasket material. Regular maintenance is necessary to ensure consistent performance.
Acoustic Concepts: STC and Rw
Acoustic performance of partitions is often described by ratings such as Sound Transmission Class (STC) or Weighted Sound Reduction Index (Rw). These ratings indicate how much sound is reduced when transmitted through the partition in controlled laboratory conditions. However, they do not directly predict field performance due to flanking paths and installation variables.
Understanding Ratings Conceptually
STC and Rw are single-number ratings derived from measurements across multiple frequencies. Higher numbers generally indicate better sound insulation, but they should not be interpreted as a simple decibel reduction. For airport holdrooms, you should discuss specific sound spectra and target levels with an acoustic consultant.
Limitations of Laboratory Ratings
In real installations, performance can be lower due to gaps, penetrations, and structural transmission. Therefore, relying solely on ratings is insufficient. A holistic approach to sealing and detailing is required.
Designing the Partition Layout
The layout of a movable wall system in a holdroom must consider not only acoustic separation but also operational flexibility and safety. The path of panels from the stacking position to the closed position must be free of obstacles and allow smooth movement.
Straight, Turning, and Stacking Routes
Review the layout to ensure that panels can move along straight runs and negotiate turns if needed. Stacking areas should be designed to store panels neatly without blocking exits or service areas. EBUNGE can review your layout to advise on feasibility.
Integration with Building Services
Holdrooms often have lighting, HVAC diffusers, sprinklers, and speakers. The partition must interface with these elements without compromising acoustic seals. For example, a gap around a sprinkler pipe can become a noise leak. Plan for sleeves and sealants at penetrations.
Pass Doors and Service Openings
Pass doors within a partition provide access for staff and passengers. They introduce additional sealing challenges. The door leaf and frame must be gasketed, and the threshold should be sealed. Door closers ensure the door returns to a sealed position.
Choosing Pass Door Configurations
Pass doors can be single or double, and can swing in or out. The choice depends on traffic flow and space constraints. In airports, doors may need to meet accessibility standards and fire codes. Discuss your requirements with the partition supplier.
Coordinate the panel seals, perimeter interfaces and adjacent fixed construction on the same drawing set.
Sealing Around Door Frames
Gaskets around the door frame and a drop seal at the bottom are essential. The door must be aligned to compress the gaskets evenly. Poor alignment can render seals ineffective.
Finish Options and Aesthetics
Holdroom partitions should not only perform acoustically but also blend with the terminal’s interior design. EBUNGE offers a range of finishes including laminate, melamine, fabric, leather, glass, and other approved surfaces. This allows you to match branding, wayfinding, and aesthetic preferences.
Surface Durability and Maintenance
In high-traffic areas, surfaces must withstand wear and be easy to clean. Laminate and melamine are durable and low-maintenance. Fabric can enhance acoustics but may require more care. Glass can create openness but may need privacy film if used in certain areas.
Integrating Branding and Signage
Partitions can incorporate graphics or signage for wayfinding. Discuss with the manufacturer to ensure that applied graphics do not compromise the surface warranty or acoustic performance.
Project Documentation and Coordination
Proper documentation is vital for successful installation. This includes detailed drawings, specifications, and coordination with other trades. EBUNGE can assist with project documentation to ensure that all stakeholders understand the requirements.
Specification Writing
Specifications should include performance criteria, finish requirements, and installation details. Avoid vague terms like “soundproof” and instead state measurable targets and test methods.
Coordination with Structural and MEP
The overhead track requires structural support to carry the panel weight. Coordinate with structural engineers to provide adequate hangers. MEP systems must avoid conflicting with the track or panel stacking zones.
