Courses
The Impact of Sound on Indoor Environmental Quality
According to the U.S. EPA, almost 90% of our time is spent indoors, emphasizing the importance of the materials that surround us. Acoustical design can enhance or diminish the experience of any space. This course will walk through the importance of designing and installing appropriate acoustical treatments, which may be about more than absorption – for example, spaces in healthcare, education, and offices rely on sound blocking for speech privacy and clear communication.
Participants will learn how acoustical ceiling and wall solutions can contribute to improved Indoor Environmental Quality (IEQ) and meet today’s most stringent sustainability requirements.
Sonic Harmony: Where Architecture Meets Acoustics
This session explores the vital role of sound in shaping healthy, sustainable, and inspiring built environments. Drawing on research in indoor environmental quality (IEQ), behavioral science, and biophilic design, it examines how acoustic design influences human well-being, productivity, and social connection. Participants will discover how to integrate acoustics seamlessly with aesthetics, using evidence-based strategies and real-world case studies to create spaces that are not only visually compelling but also sonically supportive.
