Respondents' answers to community attitudinal surveys represent impressions of soundscapes and not merely reactions to the physical noise.

Noise dose as a sole independent variable accounts only for less than half of the variance in community response data. Non-acoustic factors, such as attitude to the noise source identified by Job [(1988). J. Acoust. Soc. Am. 83(3), 991-1001] and others, reduce the unexplained variance. This paper suggests that non-acoustic factors reflect the context in which the sonic environment is perceived; hence, these factors constitute the judgments of a soundscape. Fidell et al. [(2011). J. Acoust. Soc. Am. 130(2), 791-806] show that a "community tolerance level" (CTL) is a one-number, community-specific, independent variable that represents the aggregate influence on annoyance judgments of all non-acoustic influences. Taken together these findings suggest that: (i) CTL is a one-number quantification of a soundscape, and (ii) a soundscape can be quantified by a single, numeric variable. It follows, if one can predict or calculate the single numeric quantification of a soundscape, that number will be the CTL. These results can only be true for a soundscape judged on the basis of annoyance. Virtually no data exist for which the respondents even had the possibility to rate the sonic environment positively, i.e., pleasing, so the application of CTL to soundscapes judged positively is not clear.
