As an acoustics specialist with wide-ranging experience, how would you define the concept of impact noise reduction?

Impact noise reduction is related to a floor covering that ensures higher insulation from impact noise, in accordance with ISO 10140-5. This is defined as the reduction of impact noise pressure levels, measured in the recipient room after installation of a floor covering on a 140mm thick reinforced concrete floor.
