一种被称为近场声悬浮（NFAL）的现象已经被报道，在这种现象中，几公斤重的平面物体悬浮在离辐射表面几百微米远的空气中。作者通过实验研究了水下nal的可行性，并证明了平面物体也可以在液体中悬浮。此外，还发现了一些意想不到的特性，如在某些条件下，除了排斥声辐射力之外，还会对平面物体产生吸引力。
A phenomenon called near-field acoustic levitation (NFAL) has been reported where planar objects of several kilograms in weight are levitated in the air a few hundred micrometers away from a radiation surface. The authors experimentally studied the feasibility of underwater NFAL and demonstrated that planar objects can also be levitated in liquid. Furthermore, unexpected characteristics such as that attraction, in addition to the repulsive acoustic radiation force, acts on the planar object under certain conditions, were found.
