To improve a prediction accuracy of a diffusion index method, which is calculation method on the heavy-type floor impact sound, a correction on sound fields is studied by the numerical calculation method. The correction is based on the discrepancy of sound fields between the diffuse sound field for calculation and the actual wave sound field. Through the investigation, it became clear that the sound-field correction depends on frequencies and is independent of a dimension of the room. The sound-field correction results in approximately 7 dB at around 63 Hz and becomes almost zero over 500 Hz. The present findings are useful for the above purpose on the diffusion index method and the other noise problems.
