Transformational Security invites students to a free workshop on Sound Transmission Class (STC). This session will explore the principles behind STC, the differences between STC and Noise Isolation Class (NIC) ratings, and which rating is more reliable for various applications. Attendees will gain a deeper understanding of why these metrics are essential for evaluating soundproofing effectiveness and ensuring optimal acoustic performance. Join us to expand your knowledge and learn how these ratings impact real-world environments. Our Subject Matter Expert will be available to address any further questions after the workshop.
