A laboratory study on the evaluation of soundscape

Asli Ozcevik , Zerhan Yuksel Can

This study is the second part of a research on a new approach for the evaluation of soundscape. In a previous paper, a field study of subjective evaluation through a survey form consisting of two parts (a questionnaire and a semantic differential test) was introduced. This part of the study aims to assess if the subjective evaluation of soundscapes in laboratory environment is consistent with the data obtained from the field study. The research has three steps; preparing the recordings, calculating the sound quality metrics, and realizing the laboratory study. The sound recordings are obtained by the soundwalk method at the previous areas. The original recordings, which lasted approximately 15 minutes, are edited to reduce the duration to 5 minutes to suit the laboratory tests. Sound quality metrics; loudness, sharpness, fluctuation strength and roughness, are chosen accordingly to both the pilot study and the soundscape literature. The laboratory study consisted of jury tests and listening tests. Data held from the laboratory study is statistically analyzed to attain the subjective evaluation of soundscapes. The information obtained from this study will be used in the next stage which is the comparative analysis between the field and the laboratory studies.
