What Is an Anechoic Chamber?
An anechoic chamber derived from the term “an-echoic,” meaning without echoes is a controlled room designed to eliminate sound or electromagnetic reflections It isolates internal activities from outside interference, ensuring that only direct sound is detectable. This makes the interior environment similar to being outdoors in a completely open free field
Structurally, an anechoic chamber is a shielded enclosure with sound-absorbing or radio-wave absorbing materials applied to all interior surfaces. While some chambers are compact, most are walk-in rooms that allow engineers and researchers to conduct precise testing. These chambers are widely used across aerospace, automotive, electronics, and acoustic research industries. Their high insulation levels also make them ideal for audio or video recording that demands total isolation from external noise.
With a dedicated team of acoustic engineers, we ensure that each chamber delivers exceptional performance tailored to the client’s requirements These specially constructed rooms absorb sound waves to eliminate echoes and reverberations, creating one of the quietest environments possible. The walls are lined with fiberglass wedges that absorb sound
energy, preventing reflections and delivering a true free-field acoustic space
Semi-Anechoic and Hemi-Anechoic Chambers
A full anechoic chamber absorbs energy from every direction, including the floor To achieve this, all surfaces are fitted with specialized wedges, while a mesh or perforated floor is installed above a cavity to maintain accessibility. This floor is carefully decoupled from the building structure to prevent vibration and external interference from affecting measurements.
Semi-anechoic or hemi-anechoic chambers, on the other hand, feature a solid, hard floor This design is ideal for testing heavy machinery such as vehicles, engines, industrial equipment, or appliances that cannot be supported by a suspended mesh floor. These chambers still provide excellent sound absorption on the walls and ceiling while allowing stable placement of bulky objects. Many recording studios and industrial test labs prefer semi-anechoic configurations for their practicality and versatility
Industrial Applications of Anechoic Chambers
1. Noise Test Chambers
Noise Test Chambers help eliminate workplace noise by absorbing unwanted sound through advanced acoustic panels They transform external noise into a calm, undisturbed acoustic environment suitable for testing office equipment, appliances, and communication devices with precision
2. NVH (Noise, Vibration, and Harshness) Test Chambers
NVH Chambers are essential in manufacturing and automotive sectors. They are used for evaluating the noise and vibration characteristics of components such as engines, motors, speakers, and HVAC systems
These chambers support quality control and product development by ensuring optimal acoustic performance
3. Audiometric Chambers
Designed for audiologists, acousticians, and architects, Audiometric Chambers provide strictly controlled acoustic conditions for hearing tests and research. These rooms meet stringent scientific standards and combine functional design with accurate sound isolation.
4. Semi-Anechoic Chambers
Semi-Anechoic Chambers reduce reflections, reverberations, and standing waves while offering a solid working surface. Their versatility makes them suitable for automotive testing, industrial equipment evaluation, and acoustic research requiring heavy load support.
5. Mini/Portable Anechoic Chambers
Mini Anechoic Chambers serve manufacturers of small devices and components, offering a compact and economical testing solution. They allow precise measurement of noise emissions and acoustic characteristics in a portable, controlled environment.
6. Engine Test Cell Acoustic Treatment
Engine test cells require specialized acoustic treatment to manage intense noise levels This includes insulated wall linings, high-performance acoustic doors, engineered ducting for ventilation, exhaust systems, and soundproof viewing windows. Ecotone Systems integrates all these components to achieve a safe, efficient, and acoustically optimized engine testing environment.
