Semi Anechoic Chamber | NVH Chamber Manufacturer
Semi Anechoic Chamber, anechoic chambers & NVH Chamber Manufacturer that is used for the measurement of Noise and Vibration; are designed for a 100Hz cut-off frequency using ECO-10 Anechoic Wedges which provide 0.99 % absorption.
ECOTONE™ designs and provides semi anechoic chambers for automotive testing (components / full vehicle) with a high degree of accuracy. The room is made with solid floors and walls where the ceilings are absorbent. Due to the solid floor of the room, the equipment can easily stand on the same. Vehicle Semi Anechoic Chambers are typically used for the measurement of Noise and Vibration of Vehicle during run-up, steering wheel testing, engine compartment testing, seat rail vibrations and measurement of exhaust and air intake.
ECOTONE Semi Anechoic chambers can also be used to test power train mountings, engine vibration, noise source location, structure-borne noise analysis and other components and measurement of engine power characteristics. Anechoic chambers are typically designed with a 100Hz cut-off frequency using ECO-10 Anechoic Wedges which provide 0.99 % absorption also made out from Fire retardant (FR) material.
Tests & Standards
Sound Power Level Measurement to BS ISO 3744 / ISO 3745 and BS 4196
Ecotone is a leader in the design and construction of semi-anechoic chambers, offering state-of-the-art solutions for industries that require controlled acoustic environments. Our semi-anechoic chambers are meticulously engineered to provide an accurate, noise-free environment while still allowing for the presence of certain controlled sound elements. This makes them ideal for a wide range of acoustic testing and measurement applications across various industries.
Understanding Semi-Anechoic Chambers
A semi-anechoic chamber is a specialized room designed to absorb sound reflections from the walls, ceiling, and floor, creating a space that mimics free-field conditions. Unlike full Anechoic Chambers, which absorb sound on all sides, semi-anechoic chambers have a reflective floor that allows for a more realistic testing environment where equipment or vehicles can be placed as they would be in normal operation. This design makes semi-anechoic chambers especially valuable for industries such as automotive, aerospace, electronics, and consumer goods.
Key Features of Ecotone’s Semi-Anechoic Chambers
1. Advanced Acoustic Design: Ecotone’s semi-anechoic chambers are built using advanced sound-absorbing materials, including fiberglass wedges, foam, and perforated metal panels. These materials are arranged strategically to absorb sound waves across a broad frequency range, ensuring minimal reflections from the walls and ceiling. The reflective floor is designed to support accurate sound measurements in conditions that replicate real-world scenarios.
2. Versatility for Multiple Applications: Our semi-anechoic chambers are used in a variety of testing applications. In the automotive industry, they are essential for testing vehicle noise, such as engine sounds, tire noise, and other operational sounds. Electronics manufacturers use them to evaluate the sound quality of devices like speakers, headphones, and smartphones. In the aerospace sector, these chambers are vital for testing aircraft noise, communication systems, and other critical equipment. Whatever your industry, Ecotone’s semi-anechoic chambers provide the precision and reliability needed for high-quality acoustic testing.
