Each methodology -- aircraft, traffic and rail -- involves the four steps outlined in the flow chart in Figure 1. For example, a standard interior wall, meaning two sheets of ½ inch drywall separated by wood studs and no insulation, provides an stc rating of 33, which. The tested STC ratings were less than the manufacturer's published STC ratings. Insulation will noticeably improve the STC rating of an assembly. Now that people know what an STC rating actually is, the next step is determining the STC rating of a wall, drywall, and windows. In addition, proper installation is critical to ensure that sound does not enter through poorly fitted components. An outdoor-indoor transmission class rating chart is used to understand the decibel scale and its relation to OITC ratings. STC .
