Testing electronic and electrical products for noise, vibration, and EMC compliance requires a controlled space — and for Ash & Alain India Pvt Ltd in Noida, that meant a semi anechoic chamber built to their exact operational needs. Ecotone Systems recently completed this project, delivering a chamber that pairs precision acoustic performance with a pneumatic door system for faster, easier daily use.
A semi anechoic chamber differs from a fully anechoic one in one key way: the floor stays reflective while the walls and ceiling are treated with absorptive wedges. This setup mirrors real-world ground-plane testing conditions, which is exactly what’s needed for EMC, NVH, and product noise certification work. Ecotone Systems designed the wedge layout and material density specifically around Ash & Alain’s testing frequency range, so low-frequency sound gets absorbed properly instead of bouncing off untreated surfaces.
One standout feature of this build is the pneumatic door. Chambers used for frequent daily testing need doors that open and close quickly without compromising the acoustic seal — a manual heavy door slows down workflow and wears out faster with repeated use. Ecotone Systems fitted the chamber with a pneumatic door system that combines an airtight acoustic seal with smooth, low-effort operation, letting technicians move equipment in and out multiple times a day without hassle.
Isolation from external noise and vibration was another core requirement. The semi anechoic chamber structure uses heavy composite wall panels engineered to block outside interference, keeping test readings clean and repeatable — a must for any facility running certification-grade testing. Ecotone Systems also built in acoustically-lined ventilation, so airflow and temperature control don’t undermine the chamber’s absorption performance during longer test cycles.
Ash & Alain India’s requirement reflects a pattern Ecotone Systems sees often with electronics and component manufacturers around Delhi NCR: a need for compact, efficient testing infrastructure that doesn’t demand a large fully anechoic footprint but still delivers accurate, standards-compliant results. A semi anechoic chamber hits that balance, offering ground-plane accuracy at a lower build and space cost than a fully treated room.
This project adds to Ecotone Systems’ expanding list of anechoic and semi anechoic chamber installations across India’s automotive, electronics, and industrial testing sectors. Every chamber is engineered around the client’s frequency range, door-usage pattern, and available floor space — not built from a fixed template, which is exactly why the pneumatic door made sense here.
For manufacturers running frequent EMC or acoustic testing cycles, a semi anechoic chamber with a pneumatic door setup solves two problems at once: accurate, repeatable test data and a faster daily workflow for the technicians running it. Ecotone Systems continues to bring this kind of engineering depth to test chamber projects across the country.
With the Ash & Alain India project now complete and operational in Noida, Ecotone Systems reinforces its capability in delivering testing infrastructure built around how a facility actually works, not just around a spec sheet.
