ANECHOIC CHAMBER

ANECHOIC [ an-e-koh-ik] [ cheym-ber]

An anechoic chamber (an-echoic meaning “non-refl ective, non-echoing, echo-free”) is a room designed to completely absorb refl ections of either sound or electromagnetic waves. They are also often isolated from waves entering from their surroundings.

Chamber provide high sound transmission loss (TL) characteristics and have a completely anechoic wedge lined interior to meet these requirements. The inner room is set on a vibration isolation system created for the specifi c weight and frequency cut-off of the room. These chambers are designed for applications and locations where the noise reduction characteristics for a single wall and ceiling construction provide adequate noise isolation. The single wall construction results in smaller overall outside dimensions and is particularly suited to placement in less noisy areas. In every other respect, they are similar to the Hemi-anechoic chambers with the same standard features.
