Mobile Perforated Acoustic Panels on Casters for Flexible Sound Control

Introduction

In multipurpose spaces—studios, classrooms, offices—fixed acoustic treatment often fails to match changing layouts.    **Movable perforated sound absorbing panels with caster wheels** (often called gobos in recording) enable dynamic reshaping of acoustic zones.      According to the Gobo concept, these panels serve as mobile acoustic partitions.      Recent advances in tunable perforated panels further enable variable absorption behavior.

Design & Construction Principles

• Rigid perforated substrate (MDF, plywood, or perforated metal) with typical hole diameters of 3–6 mm and open area ~5–12%.

• Backed by acoustic fill such as mineral wool, polyester fiber, or foam.

• Aluminum or steel frame with integrated locking swivel casters for stability and mobility.

• Incorporation of dampers or isolation pads near the base to minimize structural noise transfer.

• Segmented or interlocking panel edges to form continuous barriers when multiple units are used.

Applications & Use Cases

• Roll panels into modular meeting or breakout pods to reduce cross-talk.

• Use as mobile gobos in studio and broadcast to isolate microphones or control reflections.

• Deploy behind lecture speakers or stage edges to suppress rear reflections.

• Arrange panels in flexible partitions for workshops, receptions, or temporary zones.

• Review of new acoustic materials emphasizes micro‑perforated panels and hybrid composites. (ScienceDirect review on acoustic materials)

Practical Tips & Best Practices

• Ensure the caster base is wide enough to prevent tipping, especially for tall panels.

• Lock casters before use to avoid drifting during use.

• Use inter-panel gaps and overlapping edges to block leakage paths.

• Test absorption and adjust cavity depth or fill density to fine-tune performance.

• Consider hybrid designs combining perforated layers and tunable iris or rotating mechanisms. (MDPI: rotating/iris tunable panel)
