Abstract: Many animals lost their habitat with increasing human activity, especially in urban ecology. Green parks serve as an urban habitat for animals and a place of rest for people. Recently, human activity has decreased due to Covid-19, and the use of animals in green parks has changed. This research aims to identify the changes in the activities of species through the urban park's soundscape before and after COVID-19. The study was conducted through 24-hour recording twice a month in a park next to a road in metropolitan Seoul and using audio-moth (OpenAcoustics). The total recording period was from May 2019 to May 2020. In the middle of this period, social distancing due to COVID-19 was enforced. In addition, the traffic volume change data of the road next to the park was extracted from the traffic information website (SeoulTopis). The soundscape is composed of several acoustic areas including bio-phony, geo-phony, and anthro-phony. The appearance of species was confirmed through the analysis of bio-phony and anthro-phony, and the relationship between the appearance and noise and traffic volume was identified. As a result, checking the noise in the sound file, the difference was about 3dB on average (ranging from a minimum of 2.2dB to a maximum of 7.7dB). When the trend line was drawn, this noise value and traffic amount showed a decrease from 2019 to 2020. Also, it was confirmed that the number of bio-phony detections increased after social distancing and a difference in the soundscape value. Using correlation analysis, the correlation between traffic volume and soundscape index in the urban park next to the road was confirmed. Therefore, this study tried to confirm the animal's appearance before and after the COVID-19 social distancing through animal calls and noise. This research can help develop acoustic monitoring for animals in urban parks. It can also help with research related to the restoration and planning of park ecosystems between roads or residential areas in the urban ecosystem.
