When sound waves propagating in a fluid medium encounter obstacles, they reflect, refract, and scatter at the surface of the obstacles. Therefore, the interaction between objects in the sound field and the sound waves is the mutual interaction between the object and the incident sound waves, reflected sound waves, refracted sound waves, and scattered sound waves. By calculating the scattering coefficient of the object in the sound field, the acoustic radiation force can be solved according to the theory of sound wave radiation.

摘要

When sound waves propagating in a fluid medium encounter obstacles, they reflect, refract, and scatter at the surface of the obstacles. Therefore, the interaction between objects in the sound field and the sound waves is the mutual interaction between the object and the incident sound waves, reflected sound waves, refracted sound waves, and scattered sound waves. By calculating the scattering coefficient of the object in the sound field, the acoustic radiation force can be solved according to the theory of sound wave radiation.
