Participants, who were Cairo residents, were questioned about their appraisal of fami（iar urban soundscapes in a dose- and open-ended format questionnaire. Psycholinguistic data analysis of verbal descriptions expressed by respondents was conducted to identify the re（evance of semantic categories of environmental sounds and quantitative soundscape aspects for the urban sonic environment of Cairo. Resu（ts confirmed a direct retevance of the linguistic semantic auditory judgment and of the outputs of the quantitative dose-ended questions. Cairenes were also found to express their sonic environment （inguisti- cal（y based on physical properties rather than semantic features and values. Analyzing the relative annoyance increase （RAI） of the dose-ended part, overall positive RAI va（ues for all sound categories reveal how sensitive to noise Cairo residents are. Results further showed that at an RAI value of approximately 27%, sound category perception transforms from positive to negative.展开更多
