It is, however, a well-known fact that the noise level per se only explains about one-third of the variance of the annoyance response. An analysis based on the Community Tolerance Level, CTL, quantifies the combined effect of all non-acoustic factors, but does not explain the effect of each individual one. The paper is an attempt to separately quantify the effect of different non-acoustic factors.", }
