Floor impact noise is a significant inter-tenancy issue in high rise buildings. This paper, based upon over 10 years practical experience, provides an understanding of field floor impact insulation issues and discusses floor impact noise from hard flooring surfaces as it impacts into lower apartments, based on different floor finishes, type of underlay, thickness of concrete slab and ceiling construction. The standard test procedures and typical compliance limits are discussed with the analysis separated into two sections; the base building concrete slab (with and without ceiling) and different type of floor finishes with acoustic underlay. The ISO Standard methods used to assess floor impact insulation are discussed with a case study showing the performance of different floor systems (acoustic underlay samples) and different ceiling treatments. The paper concludes with a discussion of the implications of such noise for Body Corporate's and provides advice on ways in which they can mediate on floor impact noise matters.
