Embodiment Construction
[0070] The purpose of the present invention is achieved through the following technical solutions:
[0071] (1) Scene preprocessing;
[0072] (2) Calculation preprocessing;
[0073] (3) Operation processing;
[0074] The program framework of this paper can be divided into input, scene preprocessing stage, calculation preprocessing stage and running stage. According to the theory of underwater acoustics, the scattering effect of sound propagating underwater can be divided into three categories: medium scattering, object scattering and boundary scattering. The medium scattering effect and the boundary scattering effect are mainly affected by the characteristics of the water body, while the object scattering effect is mainly produced by the interaction between sound waves and complex scenes, and this is also an important factor affecting the user's perception of sound effects in the virtual environment. In the scene preprocessing stage, the frequency boundary is determined acc...
