We performed a separate analysis
for each night. A night registration consisted of one mean LAeq value
per 30 s epoch noise recording for the inside and the outside
bedroom location. We performed correlation analyses for both
conditions (T.2307 and T.TIB) and the size of the correlations was
compared between the two timeframes using a Friedman ANOVA.
We refer to Field for the categorization of the size of the correlation
effects
