A CONCEPT OF ARCHITECTURE AND ARTIFICIAL ACOUSTIC ENVIRONMENT FOR THE THEATER AUDITORIUM OF "BLACK BOX" TYPE

Architecton: Proceedings of Higher Education №4 (76) December, 2021

The article considers issues in architectural acoustic design of the theater auditorium of "Black Box" type. A transdisciplinary concept of auditorium architecture is proposed. The problem of improving speech intelligibility in the theater auditorium of "Black Box" type is addressed using the architecture and electro-acoustic immersive system based on active sound field control technologies (AFC).

VITRUVIUS ON THE VALUE OF MUSIC FOR ENHANCING THE ARCHITECTURE OF THE ANTIQUE THEATER’S AUDIENCE SPACE. Part 1

Architecton: Proceedings of Higher Education №4 (72) December, 2020

Vitruvius' legacy points to the importance of music in architecture for enhancing the acoustics of ancient theaters. In particular, he described in detail the sounding vessels, or ηχεια – “echea”, the effectiveness of which has not been proven. The effect of “echeas” on the acoustic parameters of a small classical Greek theater is investigated using computer modeling methods. The theater models developed take into account Vitruvius' recommendations and published research and measurements of ancient theater acoustic parameters reconstructed in our time. The descriptions of Vitruvius and the musical theories of Aristoxenus and Pythagoras were considered when developing the “echeas” models. Using the standard algorithm of the EASE4.4 program, the parameters of a small theater were calculated and the C50, C80, STI acoustic parameters of the theater’s sound field were found to benefit from the “echeas” or sounding vessels.

VITRUVIUS ON THE VALUE OF MUSIC IN ENHANCING THE ARCHITECTURE OF THE ANTIQUE THEATER’S AUDIENCE SPACE. Part 2.

Architecton: Proceedings of Higher Education №1 (73) March, 2021

In Vitruvius' legacy, music is noted as being important for enhancing the architectural acoustics of ancient theaters. In particular, he described in detail the sounding vessels, or ηχεια (“echea”), the effectiveness of which still has not been proven. The effect of echea on the acoustic parameters of the great classical Greek theater is investigated using computer-modeling methods. These theater models take into account the recommendations of Vitruvius and published data on the acoustic parameters of ancient theaters reconstructed in our time. The descriptions of Vitruvius and the musical theories of Aristoxenus and Pythagoras were also considered in the development of echea models. Using the standard algorithm of the EASE4.4 program, the parameters of the great theater were calculated with and without echea. Echea were found to produce a positive effect on the auditorium’s sound field acoustic parameters C50, C80, and STI.
