Acoustic characterization of the ancient theatre at Syracuse
2008
The ancient theatre at Syracuse, the largest open air theatre in Sicily, experienced many structural changes along its history. Today its very renowned drama festival attracts visitors from all the world that fill the entire cavea: customized seats accomodation and a prominent stage play an important role in the theatre acoustics. Because no data were available in literature on its acoustical perfomance a measurement session was carried out by our team in the framework of a wide research project on ancient theatres acoustics in the modern use. From data recorded "room criteria" parameters have been evaluated together with spectral analysis in order to gain a deeper information on the acoust…
New Acoustic Test Chambers at the University of Palermo
2008
Acoustic test chambers at the University of Palermo have been completed after a design optimization of existent building structures. A unique building houses five reverberation chambers, differently coupled each other in order to achieve a large flexibility on testing procedures, and offices for the staff. Main measurements offered to national and international standards include determination of sound power, sound insulation and sound absorption. Reverberation chambers present peculiar geometries in order to achieve the desidered sound fields. Chambers structure and layout within the whole building, housing all the acoustic facilities, has been designed in order to achieve strong sound insu…
Digital signal processing applied to noisy acoustic data.
2007
Frequently we deal with analog data from noisy acoustic measurements which need a preprocessing prior to the extraction of the information embedded. Data deterioration may be due to several reasons, for example: data recording on obsolete and technological poor support; bad signal conditioning (poor signal-to-noise ratio, non linearity and/or timevariance of the system under test). Sometimes information to be extracted from data is not conventional so it needs a dedicated processing. In this paper a novel audio data processing method from the autors experience in ancient open-air theatres research is shown.
STUDIO DEI DIFFUSORI DI SCHROEDER E MODELLAZIONE MEDIANTE DWM (DIGITAL WAVEGUIDE MESH)
2012
Sono stati trattati due differenti argomenti: lo studio della diffusione delle onde acustiche per mezzo dei diffusori di Schroeder e la modellazione acustica tramite la Digital Waveguide Mesh (DWM). E’ stato prima affrontato lo studio delle sequenze numeriche a spettro costante e il modo in cui esse vengono generate. La progettazione dei diffusori è stata studiata, partendo da una formulazione semplificata in campo lontano e variando i parametri di progetto sono stati ricavati i diagrammi polari di diffusione. In particolare, mediante i diagrammi polari in campo lontano è stata considerata la variazione della diffusione al variare della classe di sequenza (QRD, PRD, MLS), della lunghezza N …
