“…The indicated relations are the mathematical model of acoustical medium, and they are not the mathematical model of some concrete acoustical situation. The concretization of situation is reached by a priori setting the form of the boundary of sound field existence domain, the physical properties of boundary, the sound sources location, and initial state of medium [5][6][7].…”

The walls indeed had ears. Or rather one ear: a round hole with a tube-a kind of secret phone-to transfer all that was said in the dungeon right to the room of Signore Tomato.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
