The ERATO project and its contribution to our understanding of the acoustics of ancient Greek and Roman theatres By Jens Holger Rindel

https://www.academia.edu/65892936/The_ERATO_project_and_its_contribution_to_our_understanding_of_the_acoustics_of_ancient_Greek_and_Roman_theatres The ancient Greek and Roman theatres are famous for the excellent acoustics. However, it is not generally well known that different kinds of theatres were built, for different purposes and with different acoustical conditions. One of the aims in the ERATO project has been to investigate the acoustics of the open air theatres and compare to the smaller, originally roofed theatres, also called odea (from Greek: Odeion, a hall for song and declamation with music). The method has been to make computer models of the spaces, first as the exist today, and adjust the acoustical data for surface materials by comparison to acoustical measurements from some of the best preserved examples, namely the Aspendos theatre in Turkey and the South theatre in Jerash, Jordan. Next step was to complete the computer models in accordance with archaeological information, to make virtual reconstructions of the spaces. The acoustical simulations have given a lot of interesting information about the acoustical... ...

Predicting the Acoustics of Ancient Open-Air Theatres: The Importance of Calculation Methods and Geometrical Details By Jens Holger Rindel

https://www.academia.edu/51112641/Predicting_the_Acoustics_of_Ancient_Open_Air_Theatres_The_Importance_of_Calculation_Methods_and_Geometrical_Details?rhid=40195488311&swp=rr-rw-wc-62676792&nav_from=cacfae0d-df7a-4dc8-bcf3-22edc48ec3f3 For more than a decade now, computer simulations of sound fields in rooms have been widely adopted in research and for consulting purposes. Most computer simulations are either based on geometrical room acoustics or statistical methods, hereby neglecting diffraction and interference effects. The calculation algorithms in this type of simulations often combine the image-source method and the ray-tracing technique. In this paper, the acoustics of an open-air roman theatre are investigated. This is a special case which sets up a challenge to these prediction methods. The absence of a roof and therefore of a reverberant field, demands high accuracy in predicting the early reflections. The energy dissipates quickly in this type of enclosures and there is little masking effect of the reverberation. The inverse cone shape of these theatres also puts serious limitations to the image-source method, where great areas are in the shadow zone of the mirroring surface. Another aspect that has bee... ...

Virtual reconstructions of the Théâtre de l'Athénée for archeoacoustic study By Brian F G Katz

https://www.academia.edu/62676792/Virtual_reconstructions_of_the_Th%C3%A9%C3%A2tre_de_lAth%C3%A9n%C3%A9e_for_archeoacoustic_study The French ECHO project studies the use of voice in the recent history of theater. It is a multidisciplinary project which combines the efforts of historians, theater scientists, and acousticians. In the scope of this project an audiovisual simulation was created which combines auralizations with visualizations of former Theâtre de l'Athenee configurations issue from a series of renovations, enabling researchers to realistically perceive theater performances in foregone rooms. Simulations include the room, 2 actors on stage, and an audience. To achieve these simulation, architectural plans were studied from archives providing various details of the different theater configurations, from which the corresponding visual and room acoustic geometrical acoustics (GA) models were created. The resulting simulations allow for 360°audio-visual presentations at various positions in the theater using commercial standard hardware. ...

EVAA: A platform for experimental virtual archeological-acoustics to study the influence of performance space By Brian F G Katz

https://www.academia.edu/63928571/EVAA_A_platform_for_experimental_virtual_archeological_acoustics_to_study_the_influence_of_performance_space?rhid=40195400339&swp=rr-rw-wc-45356690&nav_from=3d2ce486-8b20-4c98-9b62-171e4690482a Research in historical musical acoustics has for several decades focused significantly on instrument fabrication. Such research has been able to highlight the acoustical impact of material and construction choices. Musicolog-ical studies have concentrated in parallel on understanding historical notation, playing styles, and even changes in musician posture over the centuries. In studying player and listener conditions in these historical studies, little attention has been given to the acoustical conditions of the performance, aside from extreme cases such as cathedral acoustic conditions. Extending the methodologies of experimental archaeology, recent advances in computational accuracy of acoustic virtual reality simulations offer the possibility to create ecologically valid reconstructions of historic sites. We present the development of an interactive immersive real-time simulator allowing musicians to perform "live" within virtual reconstructions of historic venues, com... ...
