Abstract

La ricostruzione acustica di spazi antichi, esistenti in condizioni molto diverse o non più esistenti, sta diventando un’attività sempre più diffusa in diversi campi di ricerca. La disponibilità di diversi software ha portato la simulazione acustica fuori dai laboratori specializzati e ha permesso a un pubblico molto più ampio di sfruttare le loro potenzialità. Tuttavia, come qualsiasi altro strumento di simulazione, l’affidabilità dei risultati deve essere attentamente valutata in quanto dipende da una serie di fattori relativi alla corretta conoscenza del processo di simulazione e delle caratteristiche dell’edificio da simulare.
