  • This study attempts to identify the ways of reducing the floor impact sound, by applying six different types of the reinforced bar girders and stirrup arrangements to the Structure: (1) the longer-direction girder arrangements (2) the shorter-direction girder arrangements (3) the diagonal-direction arrangements (4) the longer-direction girder arrangements with stirrups (5) the shorter-direction girder arrangements with stirrups (6) the diagonal-direction arrangements with stirrups. In order to identify the most effective structural changes, each slab was tested with bang machines, measuring the level of the sound impact. The results showed that the longer-direction girder arrangements with stirrups were the most effective one. In addition, the effectiveness of slab was found to be remarkable, showing the level of minimum 1dB to maximum 5dB, where the slab was compared with the control models without girders and stirrups. In conclusion, it is suggested that the longer-direction girder arrangements with stirrups could possibly be applied to the Wall Structures to minimize the floor impact sound.

  • 층간차음재에 대한 관심은 증대하고 있으나 실제로 우리가 층간 차음재를 선택하는데는 많은 어려움이 있다. 여기에 소개하는 재료는 기존의 성능이나 가격을 강조하는 제품과 차별화하여 건축적 관점에서 접근이 용이할 것으로 판단되는 것이다.(중략)

  • To use the impact ball as a new standard floor impact source, the objective and subjective properties of the impact bali were investigated. The results showed that not only the objective properties of the impact ball such as the Impact force exposure level, mechanical impedance but also the psychological parameters were more similar to those of the human impact than the bang machine. In addition, most of the subjects chose the impact bail sound as the most similar sound to the human impact sound in the auditory experiment.
