층간소음 성가심과 생활감에 대한 설문조사

Abstract

In order to investigate the characteristics of floor-impact sounds generated in apartment buildings and the annoyance and disturbance caused by floor-impact sounds, a questionnaire survey was conducted twice with an 11- or 12-year interval for respondents living in apartments. Questions in the survey were on the characteristics of real impact sounds, and the subjective annoyance, disturbance, or satisfaction for heavy and light impact sources. From the first survey, which was conducted in 2005, it was found that the most annoying time of day and space were 8 p.m. to midnight in the living room. It was also revealed that the main source of the floor impact sound from the upper floor is a child’s jumping and running from 6 to 9 p.m. More than half of the respondents were not satisfied by the floor impact isolation performance of their own apartments. The results of the second questionnaire survey, which was conducted from 2016 to 2017, show that 44.6 % of respondents responded that they felt annoyed by floor-impact sounds, and 38.5 % of them felt disturbed. From the results of both questionnaire surveys, it was commonly found that females are more sensitive than males, and people in their 20s are usually less sensitive than people in their 30s and 40s. It can be concluded that, for a subjective evaluation and questionnaire survey on floor-impact sounds, females in their 30s and 40s should be included in the subject group.
