Episode 69: The anechoic chamber
It is a unique “room” in Portugal that, since the 1970s, has shown the concept of artificial silence. Técnico’s anechoic chamber presents itself as if its walls (and ceiling and floor) were acoustically transparent, as they do not reflect sound and sound is lost. The chamber is a kind of fully autonomous parallelepiped isolated from the rest of the building, based on springs anchored to the base of the building. No sound can enter from the outside and there is no reflection or reverberation inside. It has played a fundamental role in the acoustics research area and will remain relevant to the study of acoustic comfort and quality.
