The majority of our underlays listed show the noise reduction properties in terms of dB so that you can make comparisons between the different products. The higher the figure, the greater the noise reduction. Please note that all our acoustic sound insulation figures are based on impact sound and not airborne sound. We recommend Super Velvet with a massive 46dB approx and Plushwalk 12mm with an even better 48dB approx rating.
