"Abstract: The goal of this paper is the acoustic characterization of the Teatro Nacional S. João (Porto, Portugal) inaugurated in 1798, but completely rebuilt in 1920 after a fire. The following parameters were measured: LAeq (without HVAC), STI (Speech Transmission Index), Reverberation Time, Clarity (C80), Definition (D50) and Central Time (ts). The main results are presented, the conclusions obtained and also the comparison with the results measured in five international opera halls and one national theater (T. Sá de Miranda, Viana do Castelo), with the same horseshoe shape. In addition, it was also compared with eleven other national theaters of various formats. " - https://lnkd.in/dF6DCe8Q

Officially inaugurated on May 13, 1798, it was the first building in Porto to be specifically conceived for the presentation of stage shows. In spite of being alternately used, not always in the most peaceful of ways, by declamatory and lyrical theatre companies, the Real Teatro de São João’s activity would eventually turn to the universe of Italian opera, presenting all the performances of that genre in Porto until the end of the 19th century.
On the night of April 11 to 12, 1908, a fire destroyed the building. In October of that same year, a public competition for its rebuilding was launched, which was won by a draft of José Marques da Silva, once described as “Porto’s last classical and first modern architect”.
The stylistic and methodological teachings absorbed at the École des Beaux-Arts, in Paris, had strengthened his fascination with the “French form”, quite clear in the rigorous and yet theatrical way in which reception, transition and performance areas are articulated. In spite of budgetary restraints, the architect was able to combine ostentation and efficiency, successfully integrating purely architectural aspects with constructive ones.
He employed an innovative technique, using concrete for the basic structure and cement mortars for the decorations. At the time it was built, the Teatro de São João combined technical innovation with a stylistic prolongation of traditional taste." Teatro Nacional S. João, https://lnkd.in/dAStSZi3
