Many countries have made statutory commitments to ensure that underwater noise pollution is at levels which do not harm marine ecosystems. Nevertheless, coordinated action to manage cumulative noise levels is lacking, despite broad recognition of the risks to ecosystem health. We attribute this impasse to a lack of quantitative management targets—or “noise budgets”—which regulatory decision‐makers can work toward, and propose a framework of risk‐based noise exposure indicators which make such targets possible. These indicators employ novel noise exposure curves to quantify the proportion of a population or habitat exposed, and the associated exposure duration. This methodology facilitates both place‐based and ecosystem‐based approaches, enabling the integration of noise management into marine spatial planning, risk assessment of population‐level consequences, and cumulative effects assessment. Using data from the first international assessment of impulsive noise activity, we apply this approach to herring spawning and harbor porpoise in the North Sea.

实践中的海洋噪声预算

许多国家已作出法定承诺,以确保水下噪声污染的水平不会损害海洋生态系统。尽管如此,尽管人们广泛认识到对生态系统健康的风险,但仍缺乏协调的行动来管理累积的噪声水平。我们将这种僵局归因于监管决策者可以努力制定的量化管理目标(或“噪声预算”)的缺乏,并提出了一个基于风险的噪声暴露指标框架,以使此类目标成为可能。这些指标采用新颖的噪声暴露曲线来量化暴露的种群或栖息地的比例以及相关的暴露持续时间。该方法论促进了基于地点的方法和基于生态系统的方法的实现,从而将噪声管理集成到海洋空间规划中,人群水平后果的风险评估以及累积影响评估。利用对脉冲噪声活动的首次国际评估得出的数据,我们将这种方法应用于北海鲱鱼产卵和海豚河豚。
