Heavy-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...
متن کاملSubjective 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 کاملDeflection of Resilient Materials for Reduction of Floor Impact Sound
Recently, many residents living in apartment buildings in Korea have been bothered by noise coming from the houses above. In order to reduce noise pollution, communities are increasingly imposing bylaws, including the limitation of floor impact sound, minimum thickness of floors, and floor soundproofing solutions. This research effort focused specifically on the deflection of resilient material...
متن کاملEffect of modulation on perceived annoyance of floor impact noise
Floor impact noise generation depends on the configuration of multistory building structures. In this study the sound radiation mechanisms between the two different structural configuration are compared through experimentation using laboratory setup of the scaled model. The transfer of vibration energy from external impact source is calculated and compared with the measured results. Parameters ...
متن کاملUnique Carbohydrate Appearance of the Floor Plate During Early Neurolation
During early neurogenesis, the floor plate plays an essential role(s) in the differentiation of the ventral portion of neural tube. In this study, we detected the specific distribution of unique glycoconjugate during the floor plate differentiation. Formalin fixed paraffin sections of BALB/c mice (10-14 embryonic days) were processed for histochemical studies using horseradish peroxidase-labell...
