Title:
SOUND WAVE PROPAGATION CALCULATION METHOD AND SOUND WAVE PROPAGATION CALCULATION DEVICE
Document Type and Number:
Japanese Patent JP2023125197
Kind Code:
A
Abstract:
To reduce computation time in calculation of acoustic wave propagation of sound waves.SOLUTION: A sound wave propagation calculation method includes the steps of: performing a first sound pressure calculation using the PE (Parabolic Equation) method to calculate sound pressure in wide distance increments from a calculation start distance to a desired calculation distance; and performing a second sound pressure calculation to calculate sound pressure in more detail than the first sound pressure calculation using the sound pressure calculated in the first sound pressure calculation from the desired calculation distance to a calculation end distance.SELECTED DRAWING: Figure 1
