Abstract

The valuation of pavements using sound aspects is crucial for a country with poor pavement conditions and a large population of visually impaired people. This study recruited sighted and visually impaired participants to conduct a �soundwalk� to appraise the urban pavements. It was held in-situ on nine renovated pavement segments in Surabaya, Indonesia. Data were collected using a questionnaire comprising open and closed-ended questions in the format of a semantic scale. The SPL was also measured to describe the sound level concerning participants� sonic perception. The semantic data were then extracted using varimax-rotated principal component analysis with a polychoric correlation. The sighted group elicits two solid soundscape dimensions; pleasantness and eventfulness. The visually impaired group evokes four soundscape dimensions; pleasantness-direction-safety, space, eventfulness, and contour. The soundscape dimensions reflect the pavements� critical factors and show that visually impaired participants appraise the pavements in more detail than the sighted.
