To make it possible to compare and check a soundproof effect by the presence or absence of impact buffer mechanisms which are a soundproof remedy or the difference thereof at the time the person planning to build a house checks the soundproof effect of a floor subjected to the soundproof remedy to noise, such as floor impact sound.
A plurality of floor models 11, 12 constituting the floor structures of the housing in simulation are installed in combination. The plural floor models 11, 12 comprise the structures different from each other; for example, the models comprise the floor model 11 having the impact buffer mechanism 23 and the floor model 12 not having the impact buffer mechanism. The person planning to build the housing is able to experience the differences, etc., in the floor impact sound by the presence or absence of the impact buffer mechanisms and the differences in the floor impact sound generated from the respective floor models by striking these floor models 11, 12.
