Abstract

Radiated noise from marine energy harvesting is of environmental and engineering interest. Here, drifting hydrophones measure underwater noise in the vicinity of a relatively small wave energy converter. A statistical approach is demonstrated for attributing range-dependent, commonly occurring sounds in the frequency band from 90 to 600 Hz. Time-delay-of-arrival localization is then demonstrated for attribution of individual acoustic events likely associated with the power takeoff and wave-hull interactions. Because the radiated noise from the wave energy converter falls below ambient levels at a range of approximately 150 m, it is unlikely to substantially affect marine life at greater distance.

将水下噪声归因于波能转换器的方法。
海洋能源收集所产生的辐射噪声具有环境和工程意义。在这里,漂流水听器测量一个相对较小的波能转换器附近的水下噪声。本文演示了一种统计方法,用于在90至600赫兹的频带中归因于与范围相关的常见声音。然后演示了可能与动力起飞和波浪-船体相互作用相关的单个声学事件的属性的到达时间延迟定位。由于波浪能转换器的辐射噪声在大约150米的范围内低于环境水平,因此不太可能对更远的海洋生物产生实质性影响。
