Acoustic measurements of the Roman theatre of Pompei by mapping the sound reflections

Researchers have mapped sound reflections in the Roman theatre of Pompeii, revealing insights into its acoustic behavior. By employing a multichannel spherical array microphone, they recorded impulse responses that allowed for the creation of an overlay video, combining 360° imagery with sound decay contours. This approach enabled the study of early and late reflections, providing a detailed understanding of sound propagation within this well-preserved monument. The findings adhere to ISO 3382-1 standards for acoustic measurements, offering valuable data on the theatre's reverberation characteristics.
