In order to improve the floor impact sound isolation performance of the apartment buildings, it is necessary to develop an effective isolation structure, and a quality control method to reduce level difference between apartment units where the isolation structure installed. To minimize the level difference between units, it is necessary to develop a construction quality control technique and acquire a related database. For controlling construction quality in the field condition, it is necessary to use a simple measurement method. In this study, a survey method for light-weight impact sound based on ISO 10052 was suggested and compared the results with KS F 2810-1 measurement results. The suggested survey method was to measure transmitted sound in the center position of the lower receiving room and impact the center position and center position with one or two more boundary position. As a survey method of light-weight impact sound, it was found that averaged level of center + one boundary position, or center to center method was useful in field condition. The level differences between the two survey methods were estimated to be ± 1.3 dB and ± 2 dB, respectively.
