Sonic environment mapping in Tunjungan road Surabaya with soundwalk method

Abstract

The soundscape analysis, based on the soundwalk method, was carried out at Tunjungan Street, which is one of the historical areas and a place of traffic. A soundwalk is one method that is used to get the impression of a soundscape. The parameters used in the assessment are acoustic parameters and semantic parameters. Acoustic parameters consist of loudness level, dynamic, and IACC. Semantic parameters are subjective judgments using 16 question items that were given by the researcher to the respondent in the questionnaire. The collection of data was done by the respondent in Tunjungan Street, which was divided into five sections or five points, and each point was measured at three times: morning, daytime, and nighttime. From the results of the study, several conclusions were drawn, namely that the morning has the largest loudness level 81 dBA. The highest dynamic span about 15 dBA and the lowest IACC value is 0.51. When daytime, it has larger loudness level and dynamic value, while at the nighttime it has the largest loudness level and IACC values in particular area only. This finding suggests that there are some part that offers comfort acoustically.
