Abstract

Soundscape assessment methods are currently being standardized and semantic differential is a common method used, as reported for instance in the Method A of the ISO/TS 12913-2:2018. However, when applying this method during surveys with non-trained participants, a deviance in scaling adjectives has been observed. This study aims at analysing the distribution of these deviances and possible systematic errors in the scaling. Data were collected through surveys in public open spaces in the UK, Italy and China. Statistical analyses were conducted over the pairs “pleasant-annoying”, “vibrant-monotonous”, “calm-chaotic”, and “eventful-uneventful” with corresponding 5-point Likert scales. The results show a scaling bias effect over adjectives that belong to the same semantic dimension. In particular, participants who gave a neutral evaluation of the adjective “pleasant”, show a systematically greater disagreement with “annoying” whereas the agreement is significantly lower. Similar patterns are observed across other pairs of adjectives. A further analysis revealed that only a small percentage of participants gave an evaluation for each pair of adjectives within a 1-point scale distance.
