## 4 Discussion and Conclusions
The perception of sound sources has mostly significant differences between China and Croatia. The natural sounds and children have positive correlation with evaluation of sound satisfaction in China; however, music has negative correlation mainly because of square dancing, which is a special activity in China. For Croatian spaces, human activities are mainly negative correlations with sound satisfaction. Natural sounds have positive correlation with overall environmental satisfaction in both China and Croatia. In particular, human sounds are positively correlated with overall environmental satisfaction, however, it is negative in Croatia. Most sound sources are mainly associated with pleasantness both in China and Croatia. Dominance of the sound of traffic is mainly negatively correlated with pleasantness in China and human sounds are mainly negatively correlated with pleasantness in Croatia. Additionally, demographical/social factors show significant influence on individual sound perception both in China and Croatia. These findings reveal that there are significant differences in soundscapes between China and Croatia within the soundscape framework. In general, it can be concluded that soundscape evaluation by people in both countries is based on the context effects of environment indicators, cultural background and type of sound sources. Three particular findings are emphasized, which can be helpful to urban designers of open public spaces in both countries:  
1. Visit purpose is the dominant factor influencing sound and environmental satisfaction both in China and Croatia. Therefore, soundscape design for both sound and overall environment has to take into account the different functions of open public spaces, such as popularity and touristic attraction of places, communities, and parks, which are directly related to different visit purposes and visit frequencies. 2. In Chinese open public spaces, the positive correlations between age of people and pleasantness is an important fact for creating an enjoyable atmosphere. Croatians pay more attention to the importance of quietness of the environment. Therefore, construction of tranquil spaces is very important and has to be taken into account when designing urban open public spaces, especially for older people, such as old-people communities. 3. In terms of sound sources in China, the main factors associated with sound and environmental satisfaction are natural and children sounds which are considered positive and should be used appropriately when designing soundscapes, while music has to be controlled as it negatively relates to satisfaction. In Croatia, contrary to China, sounds from people activities are found to be the main factors that are negatively related to sound and environmental satisfaction and pleasantness, and must consequently be controlled.
