Titled Understanding Sound Transmission Class Ratings: Attributes of Architectural Interior Door Design and Performance Criteria, this educational webinar from WDMA focuses on the primary attributes for architects and building owners when specifying architectural interior doors where sound transmission is a design consideration.

When specifying doors to address sound mitigation, it is important to understand the attributes of door design and the performance criteria that will meet design requirements for sound transmission control. The purpose of this course is to examine the primary attributes and issues related to sound control utilizing architectural interior doors with Sound Transmission Class ratings (STC). Sound Transmission Class is the rating of sound isolation of a building wall assembly or floor/ceiling assembly, and other specified materials that also make up the assembly. The rating is measured in decibels and can include doors, windows, and other openings and penetrations. The higher the STC rating number, the greater the sound isolation the building assembly achieves.

This webinar focuses on the testing criteria for Sound Transmission Class (STC) ratings based on ASTM standards, and how model building codes reference sound transmission and outline the necessary requirements, all in an effort to address the health and wellness of a building’s occupants. It also outlines the performance criteria when selecting door products to help improve the user’s experience and mitigate noise pollution. By completing this free webinar and a short quiz, you will be eligible for one AIA learning unit.
