| Outline of Final Research Achievements |
Some floors developed recently from a viewpoint of reducing noise of impact, make people feel wrong by particular foot touching. These floors were good by previous evaluation method but were considered to be inferior. First, dynamic deformation properties were measured by discrimination equipment developed to observe early stage of weight. As a result, reason of inferiority was inclination of floors nearby point of touching heel, difference of deformation between point of touching heel and surrounding it, and restoring deformation. Then, we present discrimination method of floors been inferior by compounding those factors. Next, after selecting several wooden floor coverings as a subject, performance values of hardness, foot touching, floor impact sound insulation are measured. Based on the relationship between each performance value and the vertical deformation property, the significant knowledge to develop the balanced floor to plural contradictory performance items are obtained.
