In situ testing methods for evaluating and predicting the impact isolation of high-performance floating floors - Part 2

Abstract

Floating floors using discrete isolators are commonly recommended to mitigate impact noise from fitness facilities; however, there has been little study of the performance of floating floors under the types of heavy/hard impacts that often cause noise and vibration complaints from fitness facilities. Furthermore, it can be difficult to create mock-ups of floating floor systems for in-situ testing, making it difficult to adequately evaluate their performance. Here, the authors present the beginnings of a research program intended to develop effective methods for evaluating and predicting the performance of floating floors using in-situ testing methods. Part 2 of the presentation covers the results of the measurements, including the effects of the following changes to the floating floor assembly: various air cavity depths, vented vs. un-vented air cavities, loaded vs. un-loaded floors, and concrete versus plywood floors. Finally, Part 2 presents the intended next steps in the research program.
