The carpet underlays featured here have been chosen for their sound reduction properties. Sound and noise levels are measured in DB and you should look at the DB rating on each product to determine its suitability for your needs. Please beware that the DB ratings on these carpet underlays refer to impact sound reduction - impact sound reduction defines how much noise will be prevented from traveling through the floor. Cork underlays are generally used in conjunction with another layer of different underlay and this gives excellent results.
