In this research, I have carried out research on the negative environment application of complete dry Ondol system that its necessity is increasing according to the trend of introduction of Ondol materials in corresponding antecedently to the current change of environment in domestic construction market and the demand for environment friendly construction materials. Through the measurements in laboratory, I have composed floor structures that can be applied to complete dry Ondol system and also have carried out preceding research for suggesting floor structures that can be applied to actual buildings through the evaluation of blocking performance of impact sound of floor in these floor structures. And I have suggested the final floor structures of complete dry Ondol system based on the results of tests in laboratory. I have measured impact sound of floor by applying this to actual buildings in order to evaluate the blocking performance of impact sound of floor when applying to actual sites. Summary of the results of this research is as the follows. (1) As the result of measuring impact sound of floor for both with the application of specimen of dry Ondol system and without application of the specimen in laboratory, in a single number evaluation (L'nAW) with light weight impact sound showed lower 25∼31dB compared to beforehand of application of specimen and in a single number evaluation (L'i,Fmax,AW) with heavy weight impact sound showed lower 1∼8dB except one specimen. In addition, in case of light weight impact sound, it was evaluated as 2nd and 3rd garde in the evaluation of below grades before the application of specimen. However, in case of heavy weight impact sound, the measurement number was better than beforehand of specimen application but in grade evaluation, it failed to get appraisal within grades. (2) In tests on actual sites, I have measured impact sound of floor by applying complete dry Ondol system, which was composed based on data obtained through tests in laboratory, to actual buildings. Results of a single number evaluation (L'nAW) of light weight impact sound of Room 1 and 2 in the primary measurement of impact sound of floor showed each 40 and 39 respectively and they were all evaluated as the first grade showing excellency compared to the tests in laboratory. In the second measurement, Room 1 and living room showed each 40 and 37 respectively and living room showed better result than room. (3) Results of a single number evaluation (L'i,Fmax,AW) of heavy weight impact sound of Room 1 and 2 in the primary measurement of impact sound of floor showed each 51 and 48 respectively and Room 1 was evaluated as below the grades and Room 2 was evaluated as grade four. In the second measurement, Room 1 and living room showed each 52 and 52 respectively and the both rooms showed the same lower than grade.In case of heavy weight impact sound, it showed similar or better measurement result than the tests in laboratory but the results were a little poor compared to light weight impact sound. As the results of measuring impact sound of floor, sound blocking performance of heavy weight impact sound was a little poor than light weight impact sound and also it was evaluated as lower than grade in the evaluation of grade. Therefore, it is believed to be urgent to prepare countermeasure plan to reduce heavy weight impact sound in the complete dry Ondol system.
