Origin[]
An acoustic jar, also known by the Greek name echea (ηχεία, literally echoers), or sounding vases, are ceramic vessels found set into the walls, ceilings, and sometimes floors, of medieval churches. They are believed to have been intended to improve the sound of singing, and to have been inspired by the theories of the Roman writer Vitruvius, who described their use in Greek and Roman theatres. No examples from the ancient world have survived, but examples from the Middle Ages are found in about 200 churches, about half of them in France.
Effects[]
Amplifies the decibels level of any sound that vibrates inside it, even if a low-level whisper. The released sound when left alone long enough can rupture eardrums or cause a sonic boom with enough time.
