Protecting Anechoic Chambers with Vibration Prevention Technology: Blocking Vibrations and Noise

Anechoic chambers provide an exceptionally quiet environment, but when external vibration sources (such as pumps, machinery, foot traffic, or vehicles) are nearby, low-frequency vibration noise can affect the chamber’s performance. This is where vibration prevention technology becomes critical. Enclosure employs two effective approaches—vibration isolation and vibration damping—to maintain the performance of anechoic chambers.

Vibration Isolation: Blocking External Vibrations

Vibration isolation technology involves placing isolators at the installation surface of the anechoic chamber to prevent external vibrations from affecting its performance. Enclosure uses vibration analysis software to simulate the required number and placement of isolators based on the installation site and surrounding environment. This ensures that external vibrations do not reach the chamber, safeguarding measurement accuracy.

Vibration Damping: Controlling Internal Vibrations

To ensure the anechoic chamber itself does not vibrate, damping layers are added to the walls and ceiling panels. Sonora Technology’s noise control panel, “Solameta,” integrates a specialized damping layer that converts vibration energy into heat energy, efficiently minimizing vibrations. Additionally, stiffeners and inner bolts are used in the structural design to further suppress panel vibrations.

Advanced Vibration Analysis Technology

Enclosure utilizes SolidWorks Simulation Premium for detailed 3D vibration analysis. By using vibration measurement tools like the VM-53, the characteristics of vibrations are accurately measured. This comprehensive analysis enables a thorough understanding of the vibration environment surrounding the anechoic chamber and the implementation of optimal vibration prevention measures.

Vibration prevention technology is essential to maintaining the performance of anechoic chambers. Enclosure’s vibration isolation and vibration damping techniques ensure complete control over vibrations, providing the ideal measurement environment.
