Abstract

In this paper, a method for evaluating the measurement uncertainty is proposed when measuring of floor impact sound insulation of buildings using standard heavy impact source. In addition to the effect of repeated measurements, several other factors such as measurement location, impact location, equipment used for sound pressure measurement, and heavy impact source, were considered. A mathematical model for the average maximum impact sound level and the uncertainty evaluation method for each factor were proposed. The present proposed method was applied to measurement results to evaluate the average maximum impact sound pressure level and the measurement uncertainty.

본 논문은 표준 중량충격원을 이용한 건축물의 바닥충격음 차단성능을 측정하는 경우 측정불확도를 평가하는 방법을 다루었다. 반복 측정의 영향 이외에도 측정 위치의 영향, 가진 위치의 영향, 음압측정에 사용된 장비의 영향 및 충격원의 영향 등을 고려하였다. 평균 최대 바닥충격음 레벨 측정의 수학적 모델을 제시하고 요인별 불확도 평가방법을 제안하였으며, 제안한 방법을 실제 측정 결과에 적용하여 평균 최대 바닥충격음 레벨 및 측정불확도를 평가하였다.
