JINBIAO provides 29 STC noise barriers for highways, railways, industrial facilities, and commercial noise control projects. As a professional noise barrier manufacturer, we offer bulk supply and customized panel solutions to meet different sound insulation, structural, and installation requirements.

What Is a 29 STC Noise Barrier?

A 29 STC noise barrier is an acoustic barrier designed with a Sound Transmission Class (STC) rating of 29, indicating its ability to reduce airborne sound transmission under standardized laboratory testing conditions.

Unlike NRC, which measures sound absorption, STC evaluates sound insulation performance. A 29 STC rating describes the tested assembly's airborne sound transmission characteristics, rather than a guaranteed 29 dB reduction in outdoor noise.

Key Features

• STC 29 Sound Insulation: Tested panel assemblies provide sound transmission resistance for noise control applications.

• Durable Metal Panels: Suitable for outdoor infrastructure and industrial environments.

• Customizable Specifications: Panel dimensions, thicknesses, materials, and finishes can be configured to project requirements.

• Weather-Resistant Construction: Protective surface treatments support long-term outdoor use.

• Wholesale Manufacturing: Bulk supply options for contractors, distributors, and engineering projects.
