Abstract
The interest for the acoustics of underground spaces is increasing in recent times. Since the eighties archaeologists/anthropologists have reported measurements to support theories about relationships between the acoustics of caves and the culture of prehistoric cave man. However, few studies have been published about the objective acoustics of large rooms in caves where public shows are offered. In this context the authors are collecting data for a comparative study of the locations where shows implying sound quality are performed. They had the opportunity to carry out acoustic measurements in some chambers in the Castelcivita caves located in the Cilento's National Park in Southern Italy. Because of the nature of the landscape of this karstic cave it was chosen as a natural environment to stage a show about the myth of Orpheus and Eurydice. Pressure responses to the explosion of toy balloons were recorded in six chambers where the artists perform. The subsequent analysis of acquired signals yielded single-channel room-acoustics parameters useful for the description of the quality of speech and musicI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
