Stefano M.

Acoustic Engineer

An environment is far more than barriers and textures—it's a realm of vibrational fields that resonate deeply with your essential well-being. I'm an acoustic engineer who treats sound not as a problem to solve, but as a dimension to design. With experience spanning recording studios, worship spaces, residential buildings, and environmental assessments across three continents, I bring both technical precision and intuitive understanding to every project. MY APPROACH I work at the intersection of predictive modeling and real-world implementation: • 3D acoustic simulations • Sound isolation modeling • Environmental noise mapping • On-site measurements and model calibration Every project receives data-driven analysis—not assumptions. I simulate before I specify, measure before I conclude, and deliver reports that contractors can actually build from. WHAT I DELIVER → Recording & Mixing Studios: RT optimization, isolation design, modal analysis → Worship Spaces: Speech intelligibility (STI), treatment specification → Residential: STC/IIC predictions, flanking path analysis, facade glazing → Commercial: Environmental impact studies, noise compliance, HVAC assessment Let's design the silence between the notes.
