Data and code to reproduce analyses from "Evaluating the influencers of acoustic indices in a zoo soundscape" Oliver Jepson (18520578) Tucker Gilman (10764405) Leah J Williams (15605382) Rebecca N Lewis (15606282) Ecological applications not elsewhere classified acoustic indices zoo soundscape ecoacoustics passive acoustic monitoring anthropogenic disturbance <p dir="ltr">Acoustic indices are a promising tool for ecoacoustic studies and may be useful in zoos for passive acoustic monitoring of enclosures and their inhabitants. To validate their suitability for these applications, it is important to understand how different sounds in the environment affect them. Zoos have unique soundscapes with anthropogenic sounds such as human voices and mechanical noises often prevalent alongside high levels of animal-produced sounds; however, the influence of these sounds on acoustic indices in zoos has yet to be studied. This study investigates how different sound types recorded in aviaries at Chester Zoo in 2019 and 2020 affected three widely used acoustic indices: the acoustic complexity index (ACI), the acoustic entropy index (H), and the normalised difference soundscape index (NDSI). All three indices increased with avian vocalisations; H and ACI increased with human voices but only H increased with non-vocal anthrophonic sounds; ACI and NDSI increased with biophonic sounds; and NDSI increased with wind noise, while ACI and H decreased with wind noise. Because each index captures sound types in different ways, using all three in conjunction may provide researchers and practitioners with a more detailed understanding of the acoustic environments in zoos and other anthropogenically dominated environments. </p> 2026-09-15T09:32:51Z Dataset Dataset 10.48420/28195673.v1 https://figshare.com/articles/dataset/Data_and_code_to_reproduce_analyses_from_Evaluating_the_influencers_of_acoustic_indices_in_a_zoo_soundscape_/28195673 CC BY 4.0
