The effect of acoustic environment on the impression of the landscape and the effect of the landscape on the impression of the acoustic environment were investigated by a multivariate technique using a semantic differential method. The resulting five dimensions were interpreted as "Calmness", "Activity", "Naturalness", "Uniqueness", and "Volume ...

A multi-task neural network for source localization in shallow-water environment with depth classification [PDF]
Limited high-quality training data can cause overfitting and weak generalization in deep-learning-based source localization, leading to degraded performance in realistic environments. In this study, a multi-task neural network with a depth-classification

Source localization in shallow ocean using a deep learning approach with range-dependent sound speed profile modeling [PDF]
Model-based deep learning approaches provide an alternative scheme to address the problem of the shortage of training data. However, performance degradation caused by sound speed profile (SSP) mismatch remains a critical challenge, particularly in ...
