Ocean ambient noise refers to the sum of sounds produced by natural phenomena and human activities in the ocean. With the advancement of passive acoustic technologies and signal processing methods, this noise has shifted from a traditional source of interference to an important means of acquiring seabed information and can be used to invert key geoacoustic parameters such as seabed sound speed and attenuation. This paper systematically reviews the main methods for seabed geoacoustic inversion based on ocean ambient noise and categorizes them into three types according to the principles: (1) inversion methods based on the spatial characteristics of the noise field. (2) inversion methods based on reconstructing the Green’s function via noise cross−correlation. (3) inversion methods driven by data and intelligent optimization algorithms. It analyzes key challenges faced by current methods in practical applications, including robustness, resolution, and applicability, and discusses future development directions. This study is of significant value for promoting the practical application of seabed parameter inversion methods and enhancing ocean environmental monitoring capabilities.
