Such a room was (and still is) used in acoustics to perform experiments in nominally free field conditions. This means that all sound energy travels away from the source with almost none being reflected back (hence the term echo-free room).

The lack of echo or any resonant response makes the chamber completely silent, with the world record awarded to Microsoft’s anechoic chamber, measuring at -20 decibels (Swatman, 2015).
