The Development of Standard Perceptual Attributes in Indonesian for Soundscape Evaluation: Result from Initial Study

Abstract

ISO 12913-1, 12913-2, and 12913-3 have standardized soundscape evaluation from different aspects such as definition and framework, data collection methods, and data analysis. Central to ISO 12913-2 is that an acoustic environment can be evaluated based on perceptual attributes standardized only in English. These perceptual attributes might be interpreted differently in a different country, resulting in incorrect soundscape evaluation. Thus, to overcome the problem, International collaboration was initiated to develop standard perceptual attributes for soundscape evaluation in 15 languages. This study explains the development of soundscape perceptual attributes in Indonesian. A focus group discussion had been conducted to develop the attributes in Indonesian. Afterward, in-situ experiments were carried out to identify soundscape evaluation using two different perceptual attributes both in English and in Indonesian. The Wilkinson signed-rank test analysis shows that the rating score between English and Indonesian attributes is not significant on several attributes. Those attributes are pleasant, vibrant, calm, annoying, and monotonous. The other attributes (chaotic, uneventful, and eventful) are rated differently compared to the Indonesian version. It is interesting to note that using English attributes or using a straightforward translation might not be suitable for soundscape study in Indonesia.
