A few days ago, the European Space Agency issued a series of photographs taken in one of the agency’s anechoic chambers, in the “zone of silence” as the title of the press release says. So what is an anechoic chamber? It is an echo-free room where the walls coated with special materials absorb all reflections of sound or electromagnetic waves and insulate any noise coming from outside, thus it simulates a quiet open-space of infinite dimension, which is quite useful in the aerospace industry.
