Mean ratings and standard deviations for the frequency of activity disturbances due to railway noise sorted by frequency (five-point scale from 1 = “never” to 5 = “always”).
Percentile distribution of long-term annoyance ratings due to railway noise and annoyance by railway noise perceived in the previous night (five-point scale from 1 = “not” to 5 = “very”).
Percentage of annoyed persons (categories ≥ 3: “moderately” to “very” annoyed) by rail traffic noise in the previous night as a function of the number of trains per night adjusted for subjective adaptation = 3 (median) and length of residence = 3.1 (median). The dashed lines indicate 95% confidence intervals.
Summary of univariate linear regression models for significant non-acoustical factors (p < 0.05) predicting annoyance (before the study) sorted by β- and R 2-values.
Summary of random intercept multivariate logistic regression models predicting annoyance by L Aeq, number of trains, number of freight trains, number of passenger trains, and non-acoustical factors.
Summary of generalized estimation equation models predicting subjective frequency of awakenings by L Aeq, total number of trains, number of freight trains, number of passenger trains.
