### Effect of Sound Sources
Perceived dominance of traffic (\(p<0.01\)) and horn sounds (\(p<0.01\)) have negative correlation coefficients with the pleasantness scores for Chinese places. Perceived dominance of talking (\(p<0.01\)) and walking (\(p<0.01\)), as human activities sounds, have negative correlation coefficients with the pleasantness scores for Croatian places. Other perceived human activities sound, such as children (\(p<0.01\)) and selling (\(p<0.05\)), and artificial sounds, such as music (\(p<0.05\)) and traffic sound (\(p<0.01\)), are also negatively related to the pleasantness scores for Croatian places. The result of correlation between traffic and pleasantness scores is similar to a previous study [47] done in France, Korea and Sweden. Differently, talking and walking are more related to pleasantness than traffic sound in Croatia. Weak correlations were found between the perceived dominance of music (\(p<0.05\)) and eventfulness scores in China. Human sound, such as talking (\(p<0.01\)), is positively related to eventfulness scores, however, natural sounds, such as wind (\(p<0.05\)) and water (\(p<0.05\)), are negatively related to eventfulness scores in Croatia. It is found that different types of sound sources affect soundscape quality in China and Croatia. The results correspond to previous studies [55; 56], which indicated that human activities sound and water were associated with eventfulness of soundscape. The relationships between each of the social/demographical factors and sound perception factors were analyzed based on non-parametric test and [PERSON]'s rho correlation analysis. The results are shown in Table 8. They indicate that, as for gender, there are significant differences of perceived sound sources for wind (\(p<0.05\)) and horn sounds (\(p<0.05\)) in China, and natural sounds, such as water (\(p<0.01\)) and wind (\(p<0.05\)), in Croatia. It was reported that limited effects of gender on soundscape perception exist [37], however, it can be seen that females were more sensitive than males to some sound sources, especially for Croatian places in this research. As for age group (excluding age group of older than 64), in China, age is negatively correlated to perceived dominance, such as horn sound (\(p<0.01\)) and traffic (\(p<0.05\)). By contrast in Croatia, there is a negative correlation to sounds from human activities, such as walking (\(p<0.01\)), talking (\(p<0.01\)), and children (\(p<0.01\)). As for education, in China, there is a negative correlation to perceived dominance sound from water (\(p<0.01\)) and wind (\(p<0.05\)), and positive correlation to traffic (\(p<0.01\)) and horn sound (\(p<0.01\)). Education shows no significant relationship with any sound source in Croatia, except animal sound (\(p<0.05\)). As for living place, there are significant differences for natural sounds both in China and Croatia. This finding indicates that travelers would perceive positively more natural sounds than local people. Interestingly, local people are more sensitive than travelers to artificial sounds, such as music (\(p<0.01\)), traffic (\(p<0.01\)) and horn sounds (\(p<0.05\)) in China, and to talking (\(p<0.01\)) in Croatia. As for visit frequency, in China, it is positively related to three kinds of sound sources, such as walking (\(p<0.05\)), traffic (\(p<0.05\)), and artificial sounds, such as broadcasts (\(p<0.05\)), music (\(p<0.01\)), electronics (\(p<0.05\)). In the same time, it is positively related to electronics (\(p<0.05\)), mechanics (\(p<0.05\)), and horn sounds(\(p<0.05\)) in Croatia. The result is similar to a previous study [57], which indicated that in Chinese city park, visit frequency is positively related to five kinds of sounds, especially to live music. Visit purpose is negatively related to natural sounds, especially water sounds (\(p<0.01\)) both in China and Croatia, which indicates that people who are travelers are much more sensitive to water.
