Soundproofing University Robotics Labs Using Perforated Aluminum Panels
Robotics labs are increasingly integrated into academic institutions, but their high-frequency actuators, servo drives, and cooling fans introduce disruptive noise.
This case from a Tokyo engineering university explores how perforated aluminum sheets were used to isolate noise without limiting equipment access or visibility.
📌 Acoustic Profile of Robotic Equipment
Robotic arms and gantry systems produce tonal noise in the 500–4000Hz range, overlapping with human voice frequencies.
Reverberant concrete rooms amplify this noise. The team introduced acoustic perforated panels
on mobile sound barriers and ceiling panels.
🧱 Panel Materials and Positioning
The panels consisted of 2.5mm perforated aluminum sheet (22% open area) on a PET-foam layered core.
Ceiling clouds, movable wall partitions, and bench-mounted baffles were deployed. Anti-slip perforated flooring was also added around robotic work cells.
🛠 Lab Results
Post-deployment measurements showed a 17dB(A) reduction in machine-cycle peaks.
ISO-compliant testing confirmed acoustic compliance using ISO 3744
and ASTM E1374 standards.
📈 Modular Deployment Potential
The mobile design has since been adopted in collaborative robotics zones,
STEM maker spaces, and ventilated server areas.
