摘要

海洋中人为噪声源具有时间和方向性特征。表征声景需要识别噪声源的方向性以及非方向性声压。水声矢量传感器(AVS)可以用来提供传入噪声的方向性和伴随的声压。我们提出了一项分析,从AVS测量部署在挪威峡湾,其中有频繁的商业船只交通。我们评估了各种已知和未知噪声源的方向性,并用它来解释相关的声压。峡湾声景观由人为噪声源,特别是船舶活动产生的时变噪声的方向性和强度组成。本案例研究强调了使用AVS信息来评估声景中的噪声方向性的好处。

Determining the directionality of anthropogenic noise using an underwater acoustic vector sensor: a case study in a Norwegian fjord
Sources of anthropogenic noise in the ocean have temporal and directional characteristics. Characterizing the soundscape requires identifying the directionality of the sources of noise in addition to the non-directional sound pressure. An underwater acoustic vector sensor (AVS) can be used to provide the directionality of incoming noise, and the concomitant sound pressure. We present an analysis of measurements from an AVS deployed in a Norwegian fjord in which there is frequent commercial ship traffic. We assessed the directionality of various known and unknown noise sources and used it to interpret the associated sound pressure. The fjord soundscape consists of time-varying noise directionality and intensity from anthropogenic sources, especially shipping activity. This case study highlights the benefits of using information from an AVS to assess noise directionality in a soundscape.

期刊介绍: Acta Acustica, the Journal of the European Acoustics Association (EAA). After the publication of its Journal Acta Acustica from 1993 to 1995, the EAA published Acta Acustica united with Acustica from 1996 to 2019. From 2020, the EAA decided to publish a journal in full Open Access. See Article Processing charges. Acta Acustica reports on original scientific research in acoustics and on engineering applications. The journal considers review papers, scientific papers, technical and applied papers, short communications, letters to the editor. From time to time, special issues and review articles are also published. For book reviews or doctoral thesis abstracts, please contact the Editor in Chief.
