The NVH (Noise, Vibration & Harshness) Test Chamber by Somnandi Industries is a state-of-the-art testing environment designed to measure and analyze sound and vibration behavior in automotive and industrial components. Engineered for high accuracy, this chamber provides a controlled, echo-free space for evaluating the acoustic and vibrational characteristics of engines, vehicles, appliances, and mechanical assemblies.

Our NVH test chambers are built using modular acoustic panels with advanced sound attenuation technology. The interiors are lined with PU or metallic acoustic wedges, ensuring a reflection-free and controlled test environment. The chamber flooring is vibration-isolated and designed to support heavy automotive and industrial equipment.

Whether you're measuring engine noise, appliance hum, or mechanical vibration, our chambers help you detect the smallest acoustic signatures with precision.

 

Key Features

  • 🔇 High Sound Isolation: Constructed using dense, modular panels with integrated soundproofing layers for superior external noise attenuation.

  • 🎧 Acoustic Absorption: Interior lined with precision-angled wedges (PU or metallic) to eliminate echoes and reverberations.

  • ⚙️ Vibration Isolation: Isolated flooring and structural supports prevent transmission of external mechanical vibrations.

  • 🛠 Heavy-Duty Grated Floor: Designed to support vehicles, engines, compressors, and large industrial assemblies.

  • 💡 Integrated Utilities: Built-in lighting, power connections, and data access points for real-time equipment monitoring.

  • 📏 Custom Sizes Available: Designed to match your specific test equipment and performance requirements.
