CIBRA ( was founded in 1988 and is endowed with a Laboratory of Marine Bioacoustics and Acoustical Oceanography since 1989. The activity focuses on research projects on the acoustic communication in animals, the development of equipment and protocols for the monitoring and censusing with passive acoustics, the development of advanced sound analysis methods based on the digital processing of signals.
The first phase of analysis of the enormous amount of acoustic data consists in the creation of compact daily spectrograms that show, day by day, the acoustic composition of the environment, easily distinguishing the days of wind or rain, the beautiful days and the "sound" periods mostly attributable to the nocturnal and diurnal avifauna. But we also see nocturnal passages of bats and songs of Orthoptera. Sections that will be studied analytically in order to recognize various singing species, will be chosen from this "catalog".
