The applicability of "Impactive Excitation Apparatus" to measurement of floor impact sound generated by walking was investigated. At first, excitation forces applied by walking and the apparatus were investigated. Secondly, the floor impact sounds were measured in actual wood-frame houses. As the results, it was confirmed that the floor impact sound was generated by heel landing, the frequency characteristics of the force of heel landing could be almost substituted by the apparatus, the sound in 250Hz and over hardly affected human sense, and the sounds generated by walking and the apparatus were almost the same between 31.5 and 125Hz.
