Detailed material and engineering specifications for our audiometric booths.
Every component is precision-selected to ensure maximum acoustic isolation, long-term durability, and safe operation.
100mm total wall & roof panel thickness for maximum sound attenuation.
Achieves <40 dB(A) inside from 60–65 dB(A) ambient as per OSHA norms.
All insulation materials are fire-resistant and water-repellent for long-term safety.
Fully modular panels allow easy assembly, disassembly and relocation at any time.
