Recently the impact sound insulation performance is regarded as one of the most important factor in determining the quality of apartment house. So many studies were carried out to improve these performance and to propose an appropriate evaluation method and standard of floor impact sound insulation for apartment house by psycho-acoustic method in the laboratory. This study was carried out the field psycho-acoustic test to find a correlation between physically measured values and psychological response in apartment house, and the results will be used to establish the appropriate evaluation method and standard of floor impact sound insulation.

The purpose of this study is to analysis of propagation characteristics for floor impact noise in attendance upon investigating standard of insulation performance, measurement and evaluation, understanding characteristics of a measuring factor for floor impact noise in apartment houses. Four cases which was before occupied apartment in Daegu was selected for experiment. Floor impact noise of measurement and evaluation method which are specified in the Korea Standard 2810-1, 2810-2, 2863-1 and 2863-2 was selected for this study. As the result of this study, 1) Especially, there is not a difference for apartment size, but the apartment of 40py type is lower than 30py's about $1\~2\;dB$ for light-weighted and heavy weighted impact sound. 2) The floor impact sound insulation performance is similar about measurement location of the same floor structure. 3) The floor impact sound insulation performance is not a difference about the slab area.

본 논문은 표준 중량충격원을 이용한 건축물의 바닥충격음 차단성능을 측정하는 경우 측정불확도를 평가하는 방법을 다루었다. 반복 측정의 영향 이외에도 측정 위치의 영향, 가진 위치의 영향, 음압측정에 사용된 장비의 영향 및 충격원의 영향 등을 고려하였다. 평균 최대 바닥충격음 레벨 측정의 수학적 모델을 제시하고 요인별 불확도 평가방법을 제안하였으며, 제안한 방법을 실제 측정 결과에 적용하여 평균 최대 바닥충격음 레벨 및 측정불확도를 평가하였다.

Apartment housing is a widely-spread type in Korean housing market. Nevertheless, it has caused serious problems such as traditional community corruption, unsafe structure, defects and litigation from noise. Noise, especially in concrete structure for apartment housing, is hardly controlled in proper to prevent sound transmission between upper and lower families with existing system. In foreign countries, there are floating floor system to enhance the noise control performance in multi-family housing. This study is to examine the impact sound insulation performance of floors according to the different P'yong and Layers by field measurement in highrise building.

This paper is contents about method to measure interception performance of shock noise of floor slab of apartment house to be simple. In the case of interception performance of light floor impact sound level, according to measurement method, grade of sound insulation performance showed greatly differently. But, in the case of interception performance of heavy floor impact sound level, it was similar result in all measurement method. Therefore, use of simple method of measurement was examined by possible fact in case of interception performance of heavy floor impact sound level.

Housing is demanded to convert simple dwelling space into delightful one by improving of standard of living by economic development It is interested in the impact noise of the apartment housing that is revised to housing construction criteria at 29 March 2005 and then regulated the level of floor impact noise by the rule. The plan, which is actively investigated by counterplan for the reduction of impact noise, is application of sound insulation. In generally, first target by using insulation is the reduction of floor thermal transmittance in floor heating system of apartment housing. It is recently proposed soft materials that reduce the impact noise. However, it is a fact that the application of soft sound insulation includes some problem about structural performance. In this study, we made wet-heating specimen with various sound insulations, and carried out structralexperiment for evaluating the structural safety of it.

Recently the impact sound insulation performance is regarded as one of the most import factors in determining the quality of housing environment. In order to reduce the impact sound level transmitted through the floors and structures, establishing the standard level of impact sound insulation performance is needed. In this consideration, The effecting facts for the standard insulation level is reviewed.

표준 중량 충격원의 실제 충격원 재현성에 대한 논란이 있음에도 현재 기준에서는 뱅머신 방식만 사용하고 있다. 현행 기준의 평가방법 및 등급 기준이 충격원 특성을 고려하지 못하고 있어 충격원의 선택에 따라 바닥충격음 차단 성능 등급에 차이가 발생하기 때문이다. 본 연구는 충격원 특성 외에 바닥 진동 거동 특성을 함께 고려한 현행 기준의 바닥충격음 평가 방법 고찰을 목적으로 한다. 공동주택 mock-up 실험동에서 표준 중량 충격원과 실충격원에 대하여 바닥충격음을 측정하고 이를 이용하여 해외 평가 방법과 우리나라의 평가 방법을 비교 검토하였다. 또한 현행 바닥충격음 평가 기준의 대상 주파수 범위를 벗어나는 저주파수 대역의 음압레벨은 네텔란드의 저주파 소음 인지 곡선과 국내 연구자가 제안한 저주파 소음 기준안을 이용하여 평가하였다. 그 결과 기준 및 평가 산정 방법에 따라 성능 평가 결과가 상이하며, 바닥 진동의 지배 주파수 범위에서 모든 충격원에 대한 바닥충격음 가청 소음으로 인식하여 성가시게 느낄 가능성이 매우 크다. 현행 평가 기준의 단일수치 평가량 산정 방법은 충격원에 따라 상이한 음압레벨 스펙트럼 특성을 제대로 반영하지 못하며, 바닥의 진동 거동 지배 주파수를 포함하는 저주파수 대역의 음압레벨을 고려하지 않고 있어 바닥충격음에 대한 평가 결과와 사람의 인지 수준에 차이가 발생할 수 있다. 따라서 충격원에 따른 음압레벨의 스펙트럼 특성과 저주파수 대역의 음압레벨을 반영할 수 있도록 현행 기준의 평가 방법을 보완할 필요가 있다.

Heavy-weight floor impact sound insulation performance criteria have been effective in Korea since the regulation which enforces the standard thickness of slabs in domestic apartment houses should be constructed by 180mm or 210mm was adopted. But every slab does not satisfy this criteria. So, review on existing floor impact sound insulation performance is needed to propose some basic materials for the revision of rating method. To achieve this goal, 63 field test data were checked and analyzed. The results of this study are as follows ; 1) The 210mm thickness slab has the characteristics of deeper level decrease above 120Hz frequency band than that of 180mm thickness slab's. 2) 27.5% of 180mm thickness slabs were satisfied the floor impact sound insulation performance criteria, whereas 65% of 210mm slabs do. 3) Among the main contribution frequency bands for the determination of single rating index, 63Hz was shown as the most contributive band in 210mm slabs. 4) In comparison of single rating index between bang machine test and ball test. there is a big difference between the two and this phenomenon is frequent in 210mm slab results. 5) Rating Methods for the analysis of cross-correlation between the amount of rating, the usefulness of the arithmetic mean could be secured.

The purpose of the resent research is to investigate the characteristics of sound insulation at the circular voided concrete slab in the multi-housing. In order to do this research, the method for field measurement of floor impact sound level was used following the Korea Standard F2810-1996. For the multi-housing, three kinds of circular voided concrete slabs are used to measure the characteristics of sound insulation.The results are as follows; 1.The main factor affecting the characteristics of sound insulation at the circular voided concrete slab in the multi-housing is sound-absorbing materials in the circular tube. 2. The main factor to effect the difference of sound pressure level is circular tube in the concrete slab. 3. The forms of circular tubes effect the characteristics of sound insulation at the circular tube. 4. Sound Pressure Level resulting from the piping direction of circular tubes in little different to octave band level.More study will be needed about the depth and distance of sound insulation materials, and the components of sound insulation materials for the multi-housing.
