### Effect of Sound Sources  
The results of sound sources perception in China and Croatia are shown in Figure 6. This reveals that the constitution of sound sources is mainly different between China and Croatia. The sound sources of talking and children are the most perceived, with average score 3.67 in China and 3.75 in Croatia for talking, and 3.35 in China and 3.33 in Croatia for children. In China, sound sources of music (3.08) and water (3.03) are more likely to be perceived. Compared to China, walking (3.07) and music (2.61) are also perceived in Croatia, but less than in China. It can be noted that horn sounds (2.37) and mechanics (2.02) have been perceived in China, whereas they are proportionally less perceived in Croatia. Significant differences between sound sources perception in China and Croatia have been analyzed. The sound sources of water (\(p<0.01\)), wind (\(p<0.01\)), animals (\(p<0.01\)), walking (\(p<0.01\)), selling (\(p<0.01\)), music (\(p<0.01\)), horn sound (\(p<0.01\)) and mechanical (\(p<0.01\)) have significant differences between China and Croatia. By carrying out [PERSON]'s rho correlation test, the relationship between subjective satisfaction and each sound source are examined, as shown in Table 7. It can be seen that there are correlations between satisfaction and different sound sources both in China and Croatia. Based on the analysis of constitution of sound sources in Chinese public open spaces, the main sound sources, water (\(p<0.01\)), wind (\(p<0.01\)), and children (\(p<0.05\)) have positive correlations with evaluation of sound satisfaction, however, music has a negative correlation with sound satisfaction (\(p<0.01\)). In Croatian places, main sound sources, walking (\(p<0.01\)) and talking (\(p<0.05\)), have been negatively correlated with sound satisfaction, while traffic, with a score of 2.60, and broadcast, scored on average 2.41, have negative correlations as well (\(p<0.05\)). It can be seen that natural sounds have positive correlation with sound satisfaction, especially in China. The result is consistent with other research [52], which indicated that \begin{table}

Table 6: [PERSON]’s rho correlations between subjective satisfaction, tranquility importance as well as soundscape factors, and demographic/social factors of gender, age, education, living place, visit frequency and visit purpose. natural sounds were related to positive perceptions of the urban soundscape. It is also illustrated that human sounds are the main factors to influence sound satisfaction in Croatia. It was found that water (\(p<0.01\)), wind (\(p<0.01\)), talking (\(p<0.01\)) and children (\(p<0.05\)), which are the main sound sources in China, are positively related to environmental satisfaction. Similarly, water (\(p<0.01\)) and wind (\(p<0.05\)) are positively related to environmental satisfaction in Croatia. However, walking (\(p<0.01\)) and talking (\(p<0.01\)) are negatively related to environmental
