Semantic differential analysis of the  soundscape in urban open public spaces. Building and Environment. vol.  45, n° 1. p. 150--157.The main objective of this research was to identify factors that  characterise the soundscape in urban open public spaces. The research  was carried out through a series of field surveys. Stage one, as a pilot  study, was a soundscape walk with 48 students in four typical urban open  public spaces in Sheffield. Stage two was a detailed soundscape  evaluation in two of the sites, with a total sample size of 491 from the  general public. Stage three examined the soundscape evaluation by  designers, with 223 architectural students. Semantic differential  analysis of the results shows that although the description and  evaluation of the soundscape in urban open public spaces is rather  complicated, it is still possible to identify major factors which  include relaxation, communication, spatiality and dynamics. In terms of  the general soundscape evaluation, differences between sound level and  acoustic comfort evaluation, sound preferences, and effects of  demographic factors are briefly discussed. Compared to the general  public, designers have stronger preferences to natural sounds and green  spaces, and there is also more diversity in their evaluation.
