Effects of Ambient Noise on Nestling Birds.

对于利用声音寻找资源、躲避捕食者和交流的动物来说，环境或背景噪音是一个普遍的挑战。动物有适应能力，可以减少风和雨等自然噪音的干扰。然而，他们越来越多地暴露在道路、机械和城市扩张产生的人为噪音中，这些适应可能是无效的。人类产生的噪音正在世界范围内传播和加剧，其对许多动物物种的潜在影响已被确定为紧迫的保护优先事项。

Ambient or background noise is a universal challenge for animals that use sound to find resources, avoid predators, and communicate. Animals have adaptations to reduce interference from natural noise such as wind and rain. They are, however, increasingly exposed to human-generated noise from roadways, machinery and urban sprawl, where these adaptations may be ineffective. Human-generated noise is spreading and intensifying worldwide, and its potential to impact many animal species has been identified as an urgent conservation priority.
