Ihrer Arbeit in der Originalsprache: This work aims at identifying relevant road surface
characteristics to mitigate tire-road noise of free-rolling tires using a systematic approach.
As using open porous roads is already known as an efficient measure to reduce tire rolling
noise this study will focus on compact road surfaces which have a low acoustic absorption.
Measurements on standardized ISO 10844 test tracks and on public roads are used to study the
norm's representativity and its completeness.
