Classification scheme of floor impact sounds with the standard rubber ball in dwellings
نویسندگان
چکیده
This study presents results of subjective judgments to simulated floor impact sound to create classification scheme of heavy weight impact sound with standardized rubber ball. The floor impact sound samples were recorded in a wood-frame test house with different floor configurations and were reproduced in an anechoic chamber. Using the relationship between subjective rating and physical indices, an example of classification scheme for rubber ball impact sound measurement will be presented.

Subjective evaluation of floor impact sound of wood-frame construction dwellings in different living situation
This paper presents the subjective difference of floor impact sound of wood-frame floors with different floor-ceiling systems. All impact sounds of wood-frame floors were measured in reverberation chamber with standardized rubber ball. The impact sound of concrete floor was also measured. Sheffe’s paired comparison method was used to obtain psychological scale values of each impact sound. The l...
متن کاملThe Effect of Soccer Ball Impulse on Lower Limbs of the Human Body
Despite the fact that soccer is one of the most popular sports in the world, little attention has been paid to this game scientifically which could otherwise provide a broad range of interesting outcomes. Sport equipment has a significant effect on how a game is played. Different features of the soccer ball such as its size, structure, weight and potential incoming pressure also affect the natu...
متن کاملSubjective Evaluation of Heavy/soft Impact Sound
Child running and jumping sound are one of the major noise sources in heavy structured apartment building. It was reported that physical characteristics of rubber ball (heavy/soft impact sound) was similar with child's running and jumping. As a standard impact source, rubber ball was standardized in ISO 10140 series and ISO 16283-2. However, evaluation method of rubber ball was not proposed in ...
متن کاملThe study of seismic resistance of rubber-metal supports
This research reveals the efficiency of seismic isolation system in the form of rubber-metal supports with different height buildings at multi component seismic impact. As an example, seismically insulated monolithic reinforced concrete 5, 9 and 16 story buildings are considered. The solution of the problem is obtained by a direct integration of the motion equations for an explicit scheme in fi...
متن کاملHeavy-weight Floor Impact Sound in Reinforced Concrete Structures
The purpose of this study was to evaluate the floor impact sound isolation systems in reinforced concrete constructions. The floor impact sounds were generated by the standard heavy-weight impact sources, a tyre drop tester and an impact ball. The noise and vibration from the impact sources were analyzed and the relationship between the sound levels and the subjective responses was investigated...
