In this session we will address how to solve some of the most common questions when designing audio systems: how many speakers do I need, how many meters should I place them, which model is the most appropriate according to the space and project requirements? We will explore how to design effective solutions based on real needs, using as reference the AVIXA ACU standards and the Bose Professional design guidelines. We will conduct a practical workshop where we will apply these concepts to reinforce learning and encourage active participation.
