This paper presents the process of scaling of human senses on Hardness of building floors by means of sensory test, which are the basic knowledges for its evaluating method from a viewpoint of comfortableness. Sensory scales and evaluating scales based on the subjective judgement of Hardness were made by sensory test. Evaluating scales consisted of aptitude scales of Hardness at the action and estimate scales of fatigue after the continuative action of a long time. The sensory test was taken place with 28 sample floors included various materiales and structures, 5 human actions, 6 foot wears. The number of paneles was 10〜17 males and 17 females. The method of sensory test was 'the method of successive categories'. After the sensory test, we could obtain the scales of human senses on Hardenss of building floors and confirmed its effectuality by the considerations about the results of 'analysis of variance', the relations among the scales, and others. And it made clear from the relations between sensory scales and evaluating scales, that it was possible to evaluate Hardness of building floors by the physical scale which corresponded to sensory scales.
