A review on techniques and patterns of soundscape data acquisition
Soundscape contains rich information from biology,geography,and human society,and it is a comprehensive index of the ecosystem.The monitoring of soundscape can thus be a significant content of environmental monitoring and management,and the generated soundscape data has been gradually applied in subjective evaluation of acoustic environment quality,soundscape planning,species identification,biodiversity assessment,human physical and mental health evaluation,and other aspects,with the value of which has become increasingly prominent.Nowadays,the technical parameters of the equipment that can collect soundscape data vary in the market.The ways to use the equipment are also diverse,which is not beneficial for the comparison of research results.The paper describes the critical indicators of the soundscape data acquisition equipment in detail,including the sensitivity,frequency response,and sampling rate of the microphone.The practice methods and advantages and disadvantages of three common soundscape data acquisition patterns,including manual investigation in open spaces,participatory sensing on a large scale,and long-term monitoring with fixed stations,are also summarized.With the increasing soundscape data,these issues are urgent to be considered to standardize data acquisition,including data format,data storage method,and metadata information,to improve the management and sharing of soundscape data.The biological and physiological characteristics should be taken into account regarding the heterogeneity of organisms'vocalization.Meanwhile,the future direction of the soundscape monitoring network was presented,which hopes to improve the acquisition techniques of soundscape data in our country.
