Abstract

This study attempted to develop repetitive impact sources similar to real-life floor impact noise and to find an assessment approach corresponding to this new impact source. The necessity for the development of the new impact source arises from the fact that issues related to floor impact noise in actual residential buildings mainly stem from children running. However, the standard impact sources which have been used for measuring and evaluating floor impact noise are of single-impulse type, which differs from the actual problematic impact sources. The study encompassed 18 evaluation items, and the results suggest that items applicable for assessing floor impact noise include psychological effects (annoying, becoming angry), disturbances to daily life (interference with sleep, disruption of relaxation), and physiological effects (elevated blood pressure). These items can be employed individually and, depending on the type of evaluation for floor impact noise, can be selectively utilized. By doing so, more comprehensive evaluations of auditory experiments in laboratories or assessments of residential noise in living environments related to floor impact noise could be conducted.

본 연구는 실제 생활시 주거 건물에서 발생하는 바닥충격음과 유사한 반복적인 충격원을 개발하려 시도하고, 이렇게 개발되는 새로운 충격원에 대응하는 평가 방법을 찾기 위해 수행되었다. 새로운 충격원을 개발해야 하는 필요성은 실제 주거 건물에서의 바닥충격음과 관련된 문제가 주로 어린이의 뛰는 소리에서 비롯되기 때문이다. 그러나 바닥충격음을 측정하고 평가하는 데 사용된 표준 충격원은 단일 충격 형태로, 실제 생활에서 문제가 되는 충격원과는 다른 특성을 가진다. 연구를 위해 18개의 평가 항목을 도출하였으며, 항목에 대한 설문조사 및 청취실험을 통해 바닥충격음을 평가하는 데 적용 가능한 항목으로 심리적 영향(신경쓰임, 화가 남), 일상 생활 방해(수면 방해, 휴식 방해) 및 생리적 영향(혈압 상승) 항목을 제시하였다. 이들 항목은 개별적으로 활용될 수 있으며, 바닥충격음 평가의 유형에 따라 선택적으로 활용할 수도 있다. 이를 통해 실험실에서 청취 실험의 포괄적인 평가나 바닥충격음과 관련된 주거 환경에서의 소음 평가를 더 체계적으로 수행할 수 있을 것이다.
