Venue Spaces

Large-area architectural absorption and coordinated public-address design for sports arenas, exhibition halls, transport concourses and major public event spaces.

The acoustic challenge

What the space needs

Large volumes and extensive hard surfaces allow reverberation and crowd noise to build continuously. Public announcements and emergency messages can become difficult to understand, while finishes must also satisfy fire, impact, durability, maintenance and installation-efficiency requirements.

Recommended strategy

A coordinated approach from room surfaces to sound paths.

Prioritize broad ceiling absorption, supplement it at high walls and seating backs, analyse large reflective geometries and coordinate zoned distributed loudspeakers and delay control with the architectural acoustic design.

Control reverberation and accumulated crowd noise

Protect public-address and emergency-message intelligibility

Prevent focusing from large curves, domes and glazing

Meet fire, impact, durability and maintenance requirements

Technical framework

Design every layer as one coordinated system.

Each workstream must be developed together so materials, junctions, services and system performance remain continuous from design through commissioning.

Applicable spaces

Sports arenas, exhibition halls, transport and public concourses, and large event spaces.

Main acoustic problems

Large room volumes and extensive hard finishes cause reverberation and crowd noise to accumulate continuously.
Poor public-address intelligibility can make routine announcements and emergency information difficult to identify accurately.
Materials must combine durability, fire performance, impact resistance, maintainability and efficient installation across very large areas.

Design strategy

Use large-area ceiling absorption as the primary treatment, supported by absorption on high-level walls and behind seating; avoid relying on isolated decorative patches.
Select absorptive ceilings, baffles or suspended space absorbers according to the roof structure to maximize effective absorptive area.
Analyse reflection paths from large curved surfaces, domes and glazed interfaces to prevent sound focusing.
Use zoned distributed loudspeakers and delay control for the public-address system, designed at the same time as the architectural acoustic treatment.

Recommended material systems

High-density PET absorbers, perforated metal composite acoustic panels and impact-resistant wood acoustic panels.
Acoustic baffles, suspended space absorbers and composite absorptive constructions for seating and roof areas.

Acceptance priorities

Measure reverberation and public-address intelligibility throughout seating, circulation and activity zones.
Verify sound-pressure uniformity and assess operational noise during peak crowd conditions.
Confirm the specified fire, impact, safety, durability and maintenance performance of installed materials.

System principle

Large public venues need distributed treatment rather than isolated decoration. The roof, upper walls, seating areas, major reflective surfaces and public-address coverage must operate as one coordinated safety-critical acoustic system.

Large public environments

Large-volume acoustics shaped for clarity and control.

Each scene pairs extensive absorptive coverage with durable finishes and coordinated public-address design, helping large venues remain intelligible, comfortable and adaptable under changing occupancy.

01Sports venue

Sports arenas & gymnasiums

Large-area ceiling baffles and impact-resistant wall treatment reduce crowd build-up and reverberation while supporting clear, evenly distributed announcements.

02Exhibition

Exhibition halls & galleries

Suspended absorbers and discreet wall systems control reflections across open galleries without competing with exhibits, circulation or changing display layouts.

03Public concourse

Transport & public halls

Perforated ceilings, suspended absorption and zoned loudspeakers improve announcement intelligibility throughout expansive, highly reflective public concourses.

04Large event

Large event & convention halls

High-level absorbers, wall treatment and coordinated electroacoustic coverage keep speech and programme sound controlled across flexible seating and banquet configurations.
