context_page_description: An anechoic chamber is a room designed to completely absorb reflections of either sound or electromagnetic waves. They are also often isolated from waves entering from their surroundings. The word an-echoic meaning "non-reflective, non-echoing, echo-free" is a compound word derived from Greek 'ανηχοϊκός' which is broken down to αν 'an', meaning without, ηχοϊκός 'echoic', with meaning pertaining to reflecting the sound. There are three different myths linked to the origin of the word all of them derived from the Greek mythological nymph Echo 'Ηχώ'. This combination means that a person or detector exclusively hears direct sounds, in effect simulating being inside an infinitely large room.
  Anechoic chambers, a term coined by American acoustics expert Leo Beranek, were initially exclusively used to refer to acoustic anechoic chambers. Recently, the term has been extended to RF anechoic chambers, which eliminate reflection and external noise caused by electromagnetic waves.
  Anechoic chambers range from small compartments the size of household microwave ovens to ones as large as aircraft hangars.
