Abstract

Anthropogenic noise is pervasive and may affect wildlife in many ways. Anthropogenic noise also adds to the acoustic environment's complexity, making it more difficult for animals to detect and discriminate among important signals. By integrating knowledge gained from research in experimental psychoacoustics, psychophysics, and neurophysiology into applied ecology, we can refine our understanding of the impacts of anthropogenic noise on wild populations. A multidisciplinary approach is particularly important for understanding signal perception, masking, auditory scene analysis, multimodal communication, and cross-modal interference. We demonstrate the benefits of using knowledge gained from a variety of different disciplines to understand masking effects of anthropogenic noise using our research on effects of petroleum infrastructure on grassland songbirds. Incorporating knowledge from diverse disciplines and involving several taxa, including humans, can help inform ecological conservation and management practices, and has the potential to help researchers generate novel and effective mitigation measures to counter negative effects of noise.
