Echea were placed with a "due regard to the laws and harmony of physics" according to the Roman writer [[Vitruvius]]. The number of echea used and their positioning depended on the size and shape of the theatre.<ref name="BrittonArchaeology" /> The vases operated by resonance, enhancing key frequencies of the performers' voices and absorbing those of the audience, thereby changing the sound in the theatre to make voices clearer and more lush. <ref name="AcousticalPrimer" /> |

Similar devices have been used in early churches, and some discovered in the vaulted ceiling of the choir of [[Strasbourg Cathedral]], and in [[mosque]]s dating back to the 11th century. <ref name="BrittonArchaeology" /><ref name="AcousticalPrimer" /> |
