In de stilste kamer van Nederland

What is the “stilste kamer van Nederland” at TU Delft?

The stilste kamer van Nederland (“the quietest room in the Netherlands”) is a research-grade anechoic chamber at the Technische Universiteit Delft (TU Delft). The room sits on isolated rubber-cushioned pillars, decoupled from the building, and is lined with sound-absorbing foam wedges that swallow nearly every echo. Researchers use it for acoustics work (speaker calibration, microphone testing, hearing-science studies), and it ranks among the quietest indoor spaces in Europe.

In this clip, a Dutch presenter visits the chamber and explains: “Hij staat helemaal los van het gebouw en zelfs op pilaren met rubber ertussen om elk geluidje en elke trilling buiten te houden.” The room is silent enough to hear your own heartbeat.
