Abstract

When the building becomes high, the number of households increases and they are adjacent to the elevator. So, frequency of use of elevators will increase. Elevator noise is bound to increase in the future. However, there are currently no legal standards for elevator noise or measurement and evaluation methods that can clearly measure elevator noise in Korea. Although some methods for measuring elevator noise are presented in KS F ISO 16032, this standard is not a standard established for elevator noise. It is a standard that integrates the overall measurement method of building equipment and equipment, and the position of the microphone is selected by the experimenter during measurement. Elevator noise is characterized by a low sound pressure level as the noise in the mid-low frequency band is important. However, even today, complaints from residents about elevator noise are increasing. In this study, the position of the microphone that can most sensitively pick up the elevator noise when measuring the elevator noise was studied. According to the distance from the wall and the height from the floor, a total of 9 microphone positions were measured and analyzed. As a result of the experiment, it was confirmed that the elevator noise has a very high influence in the 63 Hz band. The measured value at the center point was identified as a factor that lowered the overall elevator noise level value.

건축물이 고층화될수록 승강기와 인접한 세대 수가 증가하고 그에 따라 승강기 사용 횟수도 증가할 것이다. 그에 따라 승강기 소음은 앞으로 증가할 수밖에 없다. 하지만 현재 우리나라는 승강기 소음에 대한 법적 기준이나 승강기 소음을 명확히 측정할 수 있는 측정 및 평가 방법 또한 마련되어 있지 않다. KS F ISO 16032에 승강기 소음 측정 방법이 일부 제시되어 있지만, 이 표준은 승강기 소음을 대상으로 제정된 규격이 아니다. 건축 설비 기기의 전반적인 측정 방법을 통합하는 성격의 표준으로 측정 시 마이크로폰 위치를 실험자가 선정 하도록 되어있다. 승강기 소음은 중 저주파수대역이 중요한 소음으로 음압레벨이 낮은 것이 특징이다. 하지만 현재까지도 승강기 소음에 대한 거주자의 불만은 증가하고 있다. 이 연구에서는 승강기 소음 측정 시 승강기 소음을 가장 민감하게 수음할 수 있는 마이크로폰의 위치에 대해 연구하였다. 벽면에서부터의 이격거리와 바닥으로부터의 높이에 따라 총 9개의 마이크로폰 위치에 대해 측정 하고, 분석하였다. 실험 결과 승강기 소음은 63 Hz 대역에서 영향력이 매우 높은 소음임을 확인하였다. 중앙점에서의 측정값은 전체 승강기 소음 레벨 값을 낮추는 요인으로 확인되었다.
