Verdi theatre of Salerno: a deepening acoustic research

The Verdi theatre of Salerno is one of the Italian Opera theatres by having the horseshoe shape of the plan layout. This paper deals with the illustration of the acoustic measurements undertaken inside the main hall by graphs representation according to ISO 3382-1 as a basic evaluation. In addition, some shots extrapolated from the video of the impulse response (IR) are herein introduced to complete and deepening the acoustic study and also to show an alternative way of representation that can help the soundwaves tracing, in terms of directivity. The use of a multichannel spherical array microphone was of paramount importance for the spatial control of the wavefront propagation.
