Sound ratings quantify acoustic performance. IIC (Impact Insulation Class) measures footfall sound, while STC (Sound Transmission Class) measures airborne sound. Higher ratings indicate superior noise reduction. When selecting luxury vinyl, checking the underlayment and core composition is essential for achieving the specific sound transmission ratings required by building codes or individual needs.

How do sound transmission ratings apply to luxury vinyl flooring products?
Sound transmission ratings, such as IIC and STC, measure how well flooring limits noise. In luxury vinyl, these ratings indicate the material's ability to block or absorb impact and airborne sound, which is critical for multi-level homes or commercial installations.
