Underwater acoustics or hydroacoustics is the study of sound propagation in water and its interaction with the water's boundaries and contents. Underwater acoustics has widely attracted attention among researchers in academia and industry, because of its significant applications in a range of areas spanning from marine biology to underwater communication. Recently, advancements in underwater acoustic technologies have garnered attention for their potential to enhance underwater exploration, environmental monitoring, and subsea infrastructure inspection; by leveraging sophisticated sonar systems and acoustic sensors, researchers can achieve high-resolution imaging and precise detection of underwater objects and phenomena.
This Collection brings together original research in the field of underwater acoustics, focusing on the development and application of the next generation of acoustic technologies in order to advance our understanding of the underwater environment and to improve maritime operations. We invite contributions that explore the latest methods for underwater sound generation, propagation, and detection; topics of interest include, but are not limited to, advancements in sonar systems, acoustic communication networks, and environmental acoustic monitoring.
