Abstract

The office environment is changing according to work types, Information Technology (IT) advancements, and the Coronavirus disease (COVID)-19 situation. In order for office space users to perform their tasks comfortably and efficiently, it is necessary to secure individual privacy as well as easy communication among members. In Korea, the demand for improving the acoustic performance of office spaces is also increasing, but the related performance criteria and guidelines have not been established. In this study, standardization of office space acoustic performance measurement and evaluation methods and European countries' acoustic performance criteria were compared and reviewed. It is proposed to comprehensively review international standardization trends and acoustic performance standards in each country and to establish and utilize criteria for evaluating the acoustic performance and satisfaction of office spaces in Korea through our survey. Considering the international standardization direction and compatibility with communication and Public Address (PA) systems, it is appropriate to establish criteria using the speech transmission index or Speech Transmission Index (STI) application index. This criterion will be highly utilizable and compatible. In addition, since the office furniture industry is interested in improving the acoustic performance of office space, it is necessary to establish a labelling system for speech level reduction of office furniture.

업무 형태 변화와 Information Technology(IT) 기술 발전 그리고 Coronavirus disease(COVID)-19 상황 등에 따라 사무환경도 변화되고 있다. 사무공간 사용자가 쾌적하고 효율적으로 업무를 수행하기 위해서는 구성원 사이의 교류는 물론 개인의 프라이버시 확보가 필요하다. 우리나라도 사무공간의 음향성능 개선에 대한 요구가 증가하고 있으나, 관련 성능 기준과 지침은 수립되어 있지 않은 실정이다. 본 연구에서는 사무공간 음향성능 측정, 평가 방법의 표준화와 유럽 국가들의 음향성능 기준을 비교, 검토하였다. 국제표준화 동향과 각국의 음향성능 기준을 종합적으로 검토하고 우리나라 사무공간 음향 실태 조사 등을 통해 사무공간 음향성능과 만족도 평가 기준을 수립하여 활용하는 것을 제안한다. 국제표준화 방향과 통신, 전기음향 시스템과의 호환 등을 고려하여 음성전달지수 또는 음성전달지수 응용지표를 활용한 기준을 수립하는 것이 적절하고 활용도와 호환성이 높을 것으로 판단된다. 또한, 사무용 가구류 업계에서도 사무공간의 음향성능 개선에 관심을 나타내고 있어, 사무용 가구류의 음성 레벨 저감량에 관한 성능 기준을 수립하고 표시하는 방안을 마련하는 것이 필요하다.
