Abstract24-h digital sound recordings were undertaken at over 100 locations in the countryside of Hong Kong covering different landscapes and seasons. Spectrograms were prepared from these recordings and subdivided into segments with relatively uniform acoustic characteristics. These segments were then analyzed for their sound sources, acoustic and psychoacoustic characteristics. The segment data were further analyzed to determine the temporal structure of the soundscape in different landscapes, over the 24-h period and at different seasons of the year. Statistical analyses were undertaken to determine the variability of soundscape characteristics over space and time. The results indicated that soundscape characteristics are determined by the season and type of landscape which are reflected in the sound sources and frequency attributes. At the same time, different landscape units do exhibit similar diurnal and seasonal patterns in terms of sound sources and acoustic characteristics. These findings should have implications for countryside management and planning.
