Acoustic archeology is a field of research which inspired "Richard G. Woodbridge, who published in August 1969 an article in the journal of the eminent Institute of electrical and electronic engineers, The Proceedings of the IEEE, under the title " Acoustic Recordings From Antiquity ". The romantic scholar explained that he had carried out studies of sound recordings involuntarily engraved on the surface of ancient objects, in particular pottery. affix the needle of a vinyl turntable on the vase or the brushstroke studied and "a low frequency chatter could be heard through the headphones", supposedly the conversation of the people present during the making of the pottery ".

Unlike the mirror whose virtual image is behind, in a concave form the virtual image is in front. The perspective remains confused creating the illusion of a floating color, captive of light.
