The underwater sound distribution generated by natural sources, shipping and trawling activities has been computed by the Quonops© modelling webservice for the Northern Adriatic Sea (NAS) during 2020, a year characterized by the COVID-19 lockdown restrictions. Modelling has been calibrated by using a year-long time series of field measurements covering the domain of interest. Sound levels (50th percentile) ranged between 75 and 90 dB re 1μPa for all the considered frequencies (63 Hz, 125 Hz, 250 Hz third octave bands). Noisier NAS areas match with the shipping lanes and the distribution of trawling activity. Pressure sound indices based on masking effect were computed for two Ecologically/Biologically Significant Marine Areas (EBSA) located in the NAS. Results indicated a significant contribution of vessel and fishery-generated noise to the local soundscape and provide a basis for addressing NAS underwater noise pollution, with special reference to the Marine Spatial Planning approach.
由自然源、航运和拖网活动产生的水下声音分布已由 Quonops©建模网络服务计算，用于 2020 年的北亚得里亚海（NAS），这一年受到 COVID-19 封锁限制的影响。通过使用长达一年的涵盖相关区域的现场测量时间序列对模型进行了校准。在所有考虑的频率（63 Hz、125 Hz、250 Hz 三分之一倍频带）下，声音水平（50%分位数）在 75 到 90 dB re 1μPa 之间。较嘈杂的 NAS 区域与航运航道和拖网活动的分布相匹配。针对位于 NAS 的两个具有生态/生物重要性的海洋区域（EBSA），计算了基于掩蔽效应的声压指数。结果表明，船只和渔业产生的噪音对当地声音景观有重大影响，并为解决 NAS 水下噪声污染提供了基础，特别是在海洋空间规划方法方面。
