| 요약2 | The new accreditation scheme for the floor impact noise of apartments is announced officially by Ministry of Land, Infrastructure and Transport. According to the new accreditation scheme for the floor impact noise, the accreditation is given by the field measurement in the actual construction site. There is still uncertainty among field measurement results. Measurements were carried out in the same apartment of 19 units to quantify the uncertainty factor. The result shows that there are even 7 dB deviations among the 19 units in the single number rating scheme. Such deviations seems to be from poor quality control in construction stage and room mode due to modal overlap in low frequency ranges. Based on the results, improved measurement method for a better microphones position and increase of sample which would normalize the deviation are proposed. |
