공동주택 복합 생활소음의 통합 평가등급

Abstract

이 설문조사에서는 Table1과 같이 현 거주공간의 소음환경에 대한 전체 만족도와 현재 공동주택에서 문제시 되는 주요 소음원인 바닥충격음, 공기전달음, 급배수소음, 교통소음의 개별소음원에 대한 발생 현황과 주관적 반응요소, 만족도 등을 조사하였다. 설문조사는 수도권 공동주택에서 거주하고 실내 소음 노출시간이 가장 많은 주부 500여명을 대상으로 실시하였으며, 년령대는 30, 40대 응답자가 약 70%로 대부분을 차지하였다. 거주공간의 아파트 평형대는 거주자의 78%가 20~40평형대 아파트에 거주하고 있는 것으로 나타났다.

A survey and auditory experiment on multiple residential noises such as floor impact, airborne, bathroom, drainage and traffic noises were conducted to develop a combined rating system and to establish criteria for multiple residential noises. Subjective reactions such as annoyance, activity disturbance, sleep disturbance, and satisfaction to overall noise environment and each residential noise were recorded. The effect of individual noise perception on the evaluation of the overall noise environment was also investigated. The survey results showed that satisfaction for floor impact noise most greatly affects the overall satisfaction for overall noise environment and annoyance most greatly affects the satisfaction for individual noise sources. Auditory experiments were undertaken to determine the percent satisfaction for individual noise levels. Result of auditory experiment showed that the noise level corresponding to 40% satisfaction is 49dB (Li,Fmax,AW) for floor impact and is about 40dB(A) for airborne, drainage and traffic noise. From the results of the survey and the auditory experiments, an equation for predicting the overall satisfaction for multiple noises was developed and a classification of multiple residential noises was proposed
