### General Comparisons of Sound and Overall Environment Satisfaction Evaluation  
Sound satisfaction and overall environmental satisfaction of coastal and inland spaces in China and Croatia are shown in Figures 1 and 2. Figure 1 shows that 39.0% of respondents evaluated the sound environment in China as 0 (neither unsatisfied nor satisfied), being the most frequent answer. The average score is 0.21 of the scale from \(-\)2 to 2. Meanwhile, 54.9% of respondents evaluated the sound environment in Croatia as 1 (satisfied), as the most frequent answer. The average score is 0.61 on the scale from \(-\)2 to 2. In Figure 2, it can be seen that 21.3% respondents rated the overall environmental satisfaction in China as 0 (neither unsatisfied nor satisfied), as the most frequent answer. The average score is 1.16 on the scale from \(-\)4 to 4. Meanwhile, 35.2% of respondents evaluated overall environmental satisfaction in Croatia as 3 (very satisfied), being the most frequent answer. The average score is 2.53 on the scale from \(-\)4 to 4 in Croatia. It can be concluded that the satisfaction evaluation of sound and overall environment in Croatian places are better than those in China. Further analysis shows that there are significant evaluation differences on sound (p \(<\) 0.01) and overall environment (p \(<\) 0.01) between China and Croatia. The most probable reasons for that are the effects of environmental indicators, demographic/social factors and sound sources, as the following analysis shows. Varimax-rotated component loadings of four soundscape descriptors divided between China and Croatia are presented in Figure 3. For China, Factor 1 (49.4%) is mainly associated with agitating-calming (marked as \"A-C\" in Figure 3), boring-interesting (B-I), and uneventful-eventful (U-E). Factor 2 (26.1%) is associated with unpleasant-pleasant (U-P). This finding is similar to a previous study [48] in Korean urban parks. By contrast, for Croatia, Factor 1 (35.3%) is mainly associated with unpleasant-pleasant and agitating-calming. Factor 2 (32.8%) is associated with uneventful-eventful and boring-interesting. The factors are mainly in correspondence with the findings in a previous study [49] for European outdoor soundscape, in which study, three components of pleasantness, eventfulness, and familiarity were found. It is interesting to note that the factors are the same, however, the order is different between those two countries. The findings illustrate that semantic nuances in describing soundscape might be different between different countries because of cultural background. They are largely organized in the two varimax-rotated components of eventfulness (Factor 1) and pleasantness (Factor 2) for Chinese outdoor soundscape, and pleasantness (Factor 1) and eventfulness (Factor 2) for Croatian outdoor soundscape, respectively. From these results it can be concluded that Chinese people will like eventful sound environments more than Croatian people. Relationships among subjective satisfaction, tranquility importance and soundscape descriptors are shown in Table 3. It can be seen that sound satisfaction is positively correlated with environmental satisfaction both in China (\(p<\) 0.01) and in Croatia (\(p<\) 0.01). The importance of tranquility in public open spaces is negatively correlated with sound environment evaluation in China (\(p<\) 0.05) and in Croatia (\(p<\) 0.01), which means that the higher the requirement for environmental tranquility, the worse the evaluation of sound environmental satisfaction. Meanwhile, the importance of tranquility is negatively correlated with overall environmental evaluation in Croatia (\(p<\) 0.05), but not in China (\(p>\) 0.05). It is interesting to note that people need tranquility, however, the correlation coefficient between the tranquility requirement and sound environment satisfaction is much lower in China than in Croatia. This is mainly because people have different priority criteria for environmental satisfaction.
