        "text": "The Sound Transmission Class (STC) rating measures a window's ability to reduce airborne sound. A higher STC rating indicates better noise reduction performance. For most residential applications experiencing moderate street noise, an STC rating of 35 to 40 is often sufficient to notice a significant difference. In very noisy environments, such as next to a freeway or airport, you might consider windows with an STC of 40 or higher, sometimes reaching into the mid-50s. Our experts can help assess your specific noise concerns and recommend an appropriate STC rating for your property.",
