Room acoustic conditions of performers in an old opera house

Proposed objective criteria related to the acoustic conditions for instrume ntalists and singers have not received a sufficiently wide consent yet. In spite of this situation, it is the opinion of the authors that the measurem ent of existing criteria is useful for analysis and comparison. This paper reports the results of various acoustic measurements carried out in the Tea tro di San Carlo, Naples-Italy, with the aim of obtaining objective informa tion about its acoustics For performers. A first set of measurements was ca rried out when the theater was fitted for a symphonic concert and a second one when it was fitted for an opera performance. (C) 2000 Academic Press.
