The multiple spectral analysis are effective in case of multiple input/output for correlative inputs. In this paper, we introduce to the results of the application and evaluation of the multiple spectral analysis which is applied the matter of floor impact sound in wooden floor structure. It is shown that there are the relations of correlation in L-value and Partial Coherent Output Power Ratio (P.C.0.P.R) calculated by Partial Coherent Function in the floor impact sound and also there are the relations between the P.C.0.P. R and the impedance of transmitted vibration, etc.
