Semi Anechoic Chamber | Leading NVH Chamber Manufacturer in India
As a trusted Semi Anechoic Chamber and NVH Chamber Manufacturer, ECOTONE™ delivers advanced acoustic testing environments designed for accurate noise and vibration measurement. Our chambers are engineered with a 100 Hz cut-off frequency using ECO-10 Anechoic Wedges that offer up to 0.99 absorption, ensuring superior acoustic performance.
High-Performance Semi Anechoic Chambers for NVH Testing
ECOTONE™ develops precision-engineered semi anechoic chambers specifically for automotive components and full-vehicle testing. The room structure features solid floors and walls with a fully absorbent ceiling, allowing heavy machines, engines, or vehicles to be placed naturally for accurate testing.
These chambers are widely used for vehicle run-up noise testing, steering wheel and seat rail vibration analysis, engine compartment acoustic evaluation, exhaust and intake noise measurement, structure-borne noise analysis, engine vibration testing, and powertrain mounting assessments. All ECO-10 wedges are manufactured from fire-retardant (FR) materials, ensuring long-term safety and performance.
Tests & International Standards Supported
ECOTONE™ Semi Anechoic Chambers comply with major global standards, including BS ISO 3744, ISO 3745, and BS 4196. These standards ensure highly accurate and repeatable sound power level measurements.
What is a Semi Anechoic Chamber?
A semi anechoic chamber is a specialized acoustic room designed to simulate free-field conditions by absorbing sound reflections from the walls and ceiling. Unlike a full anechoic chamber, a semi anechoic chamber retains a reflective floor, enabling real-world testing of vehicles, large equipment, and heavy machinery. This structure makes it ideal for industries such as automotive, aerospace, electronics, consumer appliances, and industrial machinery.
Enhanced Durability and Long-Term Performance
ECOTONE™ Semi Anechoic Chambers are engineered not only for precision but also for long-term durability. Each chamber is constructed using high-quality acoustic materials, corrosion-resistant metal structures, and advanced sound isolation technologies that maintain performance even under continuous testing conditions. The chambers are designed to operate efficiently for years with minimal maintenance, ensuring consistent acoustic accuracy and a dependable testing environment. This makes Ecotone a preferred choice for organizations seeking reliable NVH testing facilities that deliver stable performance over the long term.
