exterior influences would otherwise give false results. Anechoic chambers were originally used in the context of acoustics (sound waves) to minimize the reflections of a room. More recently‚ rooms designed to reduce reflection and external noise in radio frequencies have been used to test antennas‚ radars‚ or electromagnetic interference. Anechoic chambers range from small compartments the size of household microwave ovens to ones as large as aircraft hangars. The size of the chamber depends on the
