What Is an Anechoic Chamber?
An Anechoic Chamber from Echo Acoustic is a specially engineered room built to absorb sound and prevent any form of external noise interference. Its purpose is to replicate an open, reflection-free acoustic environment where measurements remain unaffected by surrounding conditions. These chambers often achieve noise levels close to absolute silence, making them ideal for testing products that demand high acoustic precision. For industries where sound performance directly influences user experience and product reliability, Echo Acoustic provides chambers that ensure unmatched accuracy and stability.
How an Anechoic Chamber Works
The functionality of an Anechoic Chamber In India is based on two principles: absorption and isolation. At Echo Acoustic, chambers are designed with high-performance wedges that absorb sound energy and eliminate reflections. Multiple layers of steel, insulation, and vibration-damping materials form the outer shell, preventing noise from entering the chamber. Floating floors and anti-vibration mounts further reduce structural vibrations. This engineered combination allows Echo Acoustic to deliver chambers where sound measurements remain exact, consistent, and interference-free.
