David Porter and Ted Pyper, PE, INCE Bd Cert, acoustic experts from Salas O’Brien, recently presented at INCE’s Noise-Con 2023 in Grand Rapids, Michigan. Their paper, “Assessing Challenges Due to HVAC Design Constraints and Their Effects on VAV Terminal Unit Noise – Lessons Learned from Recent Projects,” shared insights from their latest work.
The paper discussed how challenging projects, such as HVAC system renovations and restrictions on certain materials and equipment, reveal that manufacturers’ data can sometimes fall short. Pyper and Porter used numerous project examples to explore various factors contributing to these issues. They emphasized the importance of in-field testing, diagnostics, and troubleshooting. Key lessons included the necessity of collaborating with mechanical engineers for accurate system settings, refining assumptions about system pressure drops and manufacturers’ data, and recognizing projects that need extra scrutiny when using this data.
David Porter, a designer at Salas O’Brien, focuses on acoustics and noise control. He holds a bachelor’s degree in audio and music engineering from the University of Rochester.
Ted Pyper, a Senior Vice President at Salas O’Brien, specializes in architectural acoustics, noise, and vibration control across diverse projects. His expertise extends to computer room modeling and environmental noise analysis. He earned his master’s degree in electrical engineering from Brigham Young University.
