These often combine laminated and double-glazed configurations with tuned As with STC, the higher the OITC number, the better the window or patio door unit keeps out unwanted noise. Sound Transmission Class (STC): The higher the STC number, the more efficient a window is at blocking outside noise. STC/OITC in building design, indicate the efficiency of a wall or floor assembly to block the transmission of sound at various frequencies Reference the above reports for complete test specimen description and data. What Are STC The definitions of two ratings: Sound Transmission Class or STC and Outdoor-Indoor Transmission Class or OITC The project’s design requirements and how STC is a widely recognized measure for sound insulation in windows and doors, focusing on human speech frequencies. What Is an OITC Rating? An OITC rating measures the sound transmission rate between external and internal spaces. The new windows’ high-performance glass and aluminum frames with thermal barriers offer acoustic performance with sound transmission class (STC) Why STC and OITC Matter in Building Acoustics STC and OITC are two of the most commonly misunderstood sound ratings in architectural specs. Two main ratings help measure how well glass blocks noise: 1. The system includes many materials other than glass, including the framing, the glazing gaskets/sealants, insulating glass unit spacer and sealants, and possibly interlayers. Broadcast studios, theatre control room windows and 5-Star hotel STC vs OITC explained: how each rating is tested, when to spec it, and why OITC is essential for windows and exterior facades.
