| Abstract | The construction of a new floor facility at NRC [1] presented an opportunity to compare sound transmission data for similar floors measured in two rather different facilities. Two issues to be resolved were whether specimen size or room volume influences the results of standard tests from 100 Hz to 4000 Hz or the results of experimental impact sound measurements at frequencies down to 50 Hz or less. An earlier paper [2] presented some early comparisons of airborne and impact sound transmission for nominally identical floors measured in the two facilities. That paper also presented sound transmission results for a wood joist floor that had been sawn into two pieces along a line parallel to the joists and each piece tested separately. Other work [3] had suggested that there ought to be a strong relationship between sound transmission at low frequencies and joist dimensions. This paper presents some sound transmission results for a floor that was progressively made smaller by sawing through the joists. As well some further comparisons between results obtained in the two NRC floor testing suites are presented. |
