        "text": "STC stands for Sound Transmission Class, and it's a single-number rating system used to measure a material's or assembly's effectiveness in reducing airborne sound. A higher STC rating indicates better sound insulation. For windows, standard single-pane windows typically have an STC of around 18-20, while specialized noise-reducing windows can achieve STC ratings of 35-40 or even higher. Understanding the STC rating helps you compare different window options and choose a product that meets your desired level of noise reduction.",
