详 情 说 明

The calculation of underwater sound far-field propagation loss is a critical aspect of underwater acoustics research. One of the methods used to compute this is through the use of parabolic equation equations. The parabolic equation method is an efficient numerical method used to simulate underwater sound propagation in the far field. With this method, it is possible to calculate the sound pressure and particle velocity field in the far field of the source. The method is based on the assumption that sound propagates in the ocean as a plane wave, which is reasonable for distances greater than the acoustic wavelength.

To perform the parabolic equation calculation, a simulation code is required. This code should be able to perform all the necessary computations required to simulate the sound propagation in the far field. The code should be able to accurately compute the acoustic pressure and particle velocity fields, taking into account the properties of the ocean medium. One example of such a code is the MATLAB-based simulation code for the parabolic equation method used to compute underwater sound far-field propagation loss. This code is designed to be user-friendly, allowing researchers and scientists to easily perform the necessary computations.

In conclusion, the use of the parabolic equation method to calculate underwater sound far-field propagation loss is an important aspect of underwater acoustics research. With the use of an appropriate simulation code, researchers and scientists can accurately compute the sound pressure and particle velocity fields in the far field of the source, taking into account the properties of the ocean medium. The MATLAB-based simulation code for the parabolic equation method is an example of a code that can be used for this purpose, providing an efficient and user-friendly way to perform these computations.
