In The assessment, quantification and understanding of measurement uncertainty over the third octave band frequency range 100-3150Hz and for single number quantities is now part of UKAS laboratory requirements under ISO17025. It is also desirable to monitor if these uncertainties change or vary over time or by virtue of the components involved in the measurement process. This study introduces the methods that can determine this and defines the basic terminology that should be applied and provides a comparison of results using a separating floor construction as an example. A suggested method is suggested of how uncertainty can be managed over time and some examples are given of the value in making periodic measurement uncertainty investigations using floor tests as a comparison
