Descripción
“The walls have ears,” as the saying goes when people tell hushed secrets behind closed doors. Surprisingly, sometimes the walls whisper back. A whispering wall is an architectural structure designed for optimal acoustic range. Words softly whispered by someone at on end are clearly heard by someone at the other end, perhaps a hundred yards distant. In this project you will explore the acoustical wonders of whispering walls, and build your own whispering wall model.
