Leaving the comfort zone and being constantly renewed means professional sustainability. The Audium team joined the growing SONarchitect family of users, acquiring the first SONarchitect license sold in Brazil, during the XXIV Annual Brazilian Acoustic Society Meeting. Since then, we have been using this incredible tool in acoustic consultancies to meet the Brazilian Performance Standard NBR 15575. The software manual guide and the YouTube videos on the Sound of Numbers channel were fundamental for the first steps. The modeling process is simple and the simulation is quickly calculated. In other words, we managed to increase our productivity. The precise interpretation of the results has allowed acoustic interventions in an optimized and personalized way even during the design phase, avoiding future problems and generating buildings that are increasingly comfortable for the users.
