Anthropogenic noise is becoming widespread in nature, leading animals to new challenges. As sounds play a fundamental role in social and reproductive behavior, human-made noise may largely impact acoustic communication. Despite a growing research effort on the topic, our understanding of these impacts are still limited. Here we provide a literature review on the effects of anthropogenic noise on anurans and birds, as well as new observational and experimental data from Iberian species, to identify knowledge shortfalls and guide future investigation. Studies found evidence that both airborne and seismic anthropogenic noise cause a plethora of behavioral responses in these taxa, although their consequences in survival and fitness remain less explored. Collaborative efforts between scientists, stakeholders and private and public institutions are imperative to create conservation guidelines and legal instruments that can mitigate the impacts of noise pollution on wildlife.
