The podcast “110 Histórias | 110 Objetos” (“110 Stories, 110 Objects”) covers the 110 years of history of Instituto Superior Técnico, through its past, present and future objects.

A collection of objects related to different fields, such as science, music, arts and sports, is the starting point for conversations with people who will tell us more about the history of these objects.

A new episode is released every week. The podcast “110 Histórias | 110 Objetos” (“110 Stories, 110 Objects”) is part of the Público newspaper podcasts.

Today’s episode (#69) – 18th November 2022: “110 Histórias | 110 Objetos” (“110 Stories, 110 Objects”) – 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.
