Abstract:
Since October 2017, 3D audio recordings have been made every month at the Vogelinsel nature reserve on Lake Altmühlsee, Germany. The recordings start one hour before and end one hour after sunset. The microphone, position and recording device are identical for all recordings. Each recording is analysed by hand using the same analysis method, whereby the content of the recordings is annotated. The weather data for the recording days is collected. The recording and weather conditions at the recording location are documented photographically. This data set is highly unique due to the 3D recording technique and the long duration of the acoustic observation of nature at one spot. In addition to collecting further data, the project aims to compare the recordings with known algorithmic bioacoustic analysis methods in order to better understand the changes in nature at the recording site (possibly caused by climate/biodiversity change), to develop further algorithmic methods of soundscape analysis and to use the recordings and additional data for nature education, medical-therapeutic and wellness contexts. The article describes the data collection in detail, outlines the comparative results achieved so far, presents our additional analysis methods and gives an outlook on the future of the project.
