Different frequencies of sound analysis and the level of the ocean sound transmission loss of longitudinal coherence, vertical coherence and other issues to explore to provide a reference to the practical application of the marine environment field analysis of the sound field.

Different frequencies of the sound field analysis and the loss of ocean acoustic fields, vertical level portrait has nothing to do with exploring issues such as the marine environment for the analysis and sound in a practical application for a reference.

Under the different frequency sound field dissemination loss analysis and the sea sound field level longitudinal coherent, is vertical waits the question to inquire into can provides certain reference for the marine environment related field analysis and the sound field practical application.

Under different frequency analysis of sound transmission loss of vertical horizontal longitudinal coherence, coherent and Ocean acoustic field analysis of problems related to the marine environment and the practical application of sound field with a certain reference.
