| 摘 要： | 随着海洋、湖泊、河流和港口等人类活动逐渐增加，涉海工程产生的水下噪声污染及对海洋生物影响已引起广泛关注。工程建设期环境影响评价中，水下噪声测量逐渐成为海洋监管的要素。水下冲击打桩是工程建设中常见的低频水下脉冲声源，能够传播较远距离。如何规范地开展水下冲击打桩噪声测量至关重要。文章给出了水下冲击打桩噪声的通用测量方法，包括声学指标、测量系统、测量布放、声学测量配置、测量不确定性等，可为海洋工程建设影响评价、海洋生物生态保护等提供技术支撑。

| Abstract: | The increasing number of sound producing human activities in oceans,seas,lakes,rivers,and harbors has led to concern over underwater noise pollution from unwanted sound and its potential effect on aquatic life.In the environmental impact assessment during the construction period of marine engineering,the measurement of underwater noise gradually becomes an element of marine management and supervision.Percussive pile driving is a significant source of low frequency impulsive underwater sound,which can propagate over large distances.It is very important to establish a standardized measurement method of underwater percussive pilling noise.The paper provided a general measurement method for underwater percussive pilling noise,including acoustic metrics,measurement equipment,deployment for measurement,acoustic measurement configuration,and measurement uncertainty,etc..The results can provide technical support for the impact assessment of marine engineering construction and the marine ecological protection. |
