Selected aspects of acoustic treatment of the orchestra pit

Kamisiński Tadeusz, Brawata Krzysztof

Vibrations in Physical Systems

2023

Vol. 34, nr 1

art. no. 2023104

The orchestra pit is not a friendly workplace for musicians, and the need to ensure their interaction with the stage and audience places very high demands on this interior. The aim of the considerations presented in the article was to analyse the various possibilities of acoustic adaptation of the orchestra pit against the background of obtaining the expected effects. The conducted simulation studies and the use of the results of the experimental studies carried out in the well-equipped orchestra pit of the Krakow Opera allowed for the indication of representative acoustic parameters useful for the assessment of the results of acoustic treatment. Based on the comparison of the reverberation time T20 and EDT for various variants of the orchestra pit interior, the confirmation of the legitimacy of using sound diffusing and absorbing systems was obtained. They spread the energy of the first sound reflections in time and reduce the risk to the musicians' hearing. Reflective elements and sound dispersing within the orchestral will ensure adequate audibility between the musicians.
