ANECHOIC CHAMBER

An anechoic chamber is a room in which there are no echoes. This description was originally used in the context of acoustic (sound) echoes caused by reflections from the internal surfaces of the room but more recently the same description has been adopted for the radio frequency (RF) anechoic chamber. An RF anechoic chamber is designed to suppress the electromagnetic wave analogy of echoes: reflected electromagnetic waves, again from the internal surfaces. Both types of chamber are normally constructed, not only with echo suppression features, but also with effective isolation from the acoustic or RF noise present in the external environment. In a well designed acoustic or RF anechoic chamber, the equipment under test will only receive signals which were emitted directly from the signal source and not reflected from another part of the chamber. We make use of sophisticated technology for manufacturing these and ensure that these offer complete satisfaction to our clients.

Acoustic Anechoic Chambers

Acoustic Anechoic Chambers are commonly used in acoustics to perform experiments in nominally free field conditions. This means that all sound energy will be traveling away from the source with almost none being reflected back. Common anechoic chamber experiments include measuring the transfer function of a loudspeaker or the directivity of noise radiation from industrial machinery. Anechoic chambers are also generally very quiet chambers with typically noise levels in the 20-25 dBA range.
