        "text": "STC stands for Sound Transmission Class, which is a single-number rating system for how well a building material or assembly blocks airborne sound. A higher STC rating indicates better sound insulation. For windows, typical STC ratings range from 25 to 35 for standard units, while specialized noise-reducing windows can achieve STC ratings of 35 to over 40. When selecting windows for noise problems, looking for a higher STC rating is a key indicator of its effectiveness in blocking unwanted sound from entering your home.",
