What are anechoic chambers

What anechoic chambers are for

The anechoic chambers are a specialized room designed to minimize or eliminate echoes, reverberations, and external sound sources. These rooms are commonly used for scientific experiments, acoustic testing, and product development. These are typically made with sound-absorbing materials, such as fiberglass or foam wedges, which can absorb sound waves and prevent them from reflecting off the walls, ceiling, and floor of the room. The walls and ceiling of the chamber are often lined with thick foam wedges, while the floor may be made of steel mesh or another material that can allow sound to be absorbed. The design ofit  requires a high degree of precision to ensure that it truly eliminates echoes and reverberations. Even the smallest irregularities in the surfaces of the walls or ceiling can create reflections that can disrupt the acoustic measurements being taken inside the chamber. These are used in a variety of applications, including aerospace engineering, automotive testing, and acoustic research. They are also used to test the performance of audio equipment, such as speakers and microphones, as well as to study the behavior of sound waves in different environments. Overall, they are critical tools for scientific research and product development, as they provide a controlled environment where acoustic measurements can be taken with a high degree of accuracy and precision.

Who to contact 

Over the years, GTEM Italia has become a real point of reference in the field of anechoic chambers. These are rooms designed to completely absorb reflections of sound or electromagnetic waves. They are also often isolated from waves from the surrounding environment. This combination results in a person or detector hearing only direct sounds, effectively simulating being inside an infinitely large room. Chambers are either made up of small compartments or much larger dimensions. The size of the chamber depends on the size of the objects and the frequency ranges to be tested.
