Abstract
Soundscape research could provide more information about urban acoustic environment, which should be integrated into urban management. The aim of this study is to test how landscape spatial pattern could affect soundscape perception. Soundscape data on specifically defined spatial and temporal scales were observed and evaluated in a multi-functional urban area in Rostock, Germany. The results show that urban soundscapes were characterised by artificial sounds (human, mechanical and traffic sounds) overwhelming the natural ones (biological and geophysical sounds). Major sound categories were normally mutual exclusive and dynamic on temporal scale, and have different spatial distribution on spatial scale. However, biological and traffic sounds seem to be co-existing on both temporal and spatial scales. Significant relationships were found existing between perception of major sound categories and a number of landscape spatial pattern indices, among which vegetation density (NDVI), landscape shape index (LSI) and largest patch index (LPI) showed the most effective indicating ability. The research indicated that soundscape concepts could be applied into landscape and urban planning process through the quantitative landscape indices to achieve a better urban acoustic environment.

Correlation analysis showed that soundscape preference was significantly and positively correlated with geophysical sound and biological sound, and negatively correlated with mechanical sound and traffic sound, but there was no significant relationship with human sound
It can be seen that human sound was negatively correlated with traffic sound and biological sound in seven and five periods, respectively

In the area of urban acoustics, combining soundscape concept into the planning process is thought to be the most effective and practical way to realise a better acoustic environment (Raimbault, Dubois 2005; Guastavino 2006; Adams et al 2006; De Coensel et al 2010). Researches on the aural aspect of landscape have been drawing more attention, but mainly focusing on aural-visual interactions in landscape perception, treating sound as an important factor affecting landscape preference by human beings (Pheasant et al 2008). Liu et al (2013b) found that urban soundscape perception showed a relationship with underlying landscape characteristics. Compared with visual perception, which is related only to the landscape characteristics in viewshed, sounds can propagate and be perceived by humans through the local landscapes even the sound sources are visually hidden
