Sound-Dampening Enclosures for Robotics Testing Labs Using Perforated Aluminum Sheets
Robotics testing centers must balance mechanical experimentation with worker safety—particularly in controlling mechanical noise.
This article explores how perforated aluminum sheets were used to construct acoustic enclosures for collaborative robot cells at a German automation lab.
📌 Testing Noise Profile
Collaborative robots generate cyclic motion noise and fan-driven vibrations during endurance tests.
The lab required both acoustic suppression and line-of-sight for remote monitoring.
Acoustic perforated panels were selected for this dual function.
🧱 Enclosure Design
Wall frames used 2.2mm perforated aluminum sheet (28% perforation), bonded to acoustic PET foam.
Corner posts integrated transparent polycarbonate for observation.
Floors were fitted with anti-slip perforated panels for vibration isolation and airflow.
🛠 Performance Evaluation
Reverberation time dropped from 1.6s to 0.55s.
ISO-compliant testing using ISO 11690 and
ASTM C423 confirmed a 19dB(A) noise reduction at the boundary.
📈 Broader Application Use
Similar acoustic systems have been installed in vision-guided robotic labs,
industrial mechatronic training rooms, and test hoods for drone propeller cells.
