4. Results of Experiment I
4.1. Results of condition (a) “audio sample only”
At first the differences between the comfort soundscape assessment were examined. A median test was applied to decide whether the differences between the 7 investigated soundscapes were statistically reliable. The main result shows a significant difference for the investigated soundscapes [chi2(6, N = 17) = 80.608; p < 0.001]. However, detailed pair comparisons show that SGI-1027 there were no significant differences between the soundscapes 2, 3, 4 and 5, 6, 7. A clear size effect is observed in Fig. 3, with three groups of different soundscapes. Soundscape A1 belongs to the group 1, soundscapes A2, A3, A4 to group 2 and soundscapes A5, A6, A7 to group 3.

Although for other sound levels the results of prothallus analyses look different, the monotonic function of the comfort value occurs for all the sound levels (see Fig. 3). The difference of 6 dB does not create a different comfort assessment with the following soundscapes: A1, A2, A3, A4, A5, and A7.
