Reflected walking sound reduction (RWS)
Walking noise heard in the same room is known as reflected walking sound. Suitable underlays can noticeably reduce reflected walking sound. The test standard for determining so-called RWS values is still in development, so no generally accepted test method is available yet. Once the new test standard is issued, specific recommendations for minimum requirements can be given. Nevertheless, today it can be said that the higher the RWS value (reflected walking sound reduction), the better.
