How did sound propagate inside the Mosque of Cordoba in the time of Abd al-Rahman I? Today, thanks to virtual simulation tools, it is possible to know the sound fields of spaces that no longer exist. This field of work is known as acoustic archaeology by some researchers. Working in this field, researchers from the Higher Technical School of Architecture at the University of Seville have carried out a study in which they have determined the variation of the acoustic parameters such as reverberation, clarity or definition in the Mosque of Seville.
