The impact of vehicular noise on the effectiveness of acoustic indices

Passive acoustic monitoring (PAM) is a sampling technique that has gained increasing popularity in the field of wildlife monitoring and research. The technique involves the deployment of programmable autonomous recording units, allowing for non-invasive and cost-effective collection of acoustic information across a breadth of temporal and spatial scales. Retrieving biological information from PAM recordings can often involve time-consuming sound annotation methodologies, but the advent of acoustic indices has allowed for biodiversity metrics to be estimated quickly and with reasonable accuracy.
While correlations between acoustic indices and species richness have been observed in a variety of ecological contexts, these relationships tend to faulter in environments with increased vehicular noise. In turn, many researchers will avoid areas with vehicular traffic for PAM with intent on using acoustic indices. Here, we assessed the direct impact of vehicular noise on nine acoustic indices t..., , , # THE IMPACT OF VEHICULAR NOISE ON THE EFFECTIVENESS OF ACOUSTIC INDICES
