The modal spectra of the three-dimensional
sound field (abbreviated as MOS3DPEF) are
determined by integration of the
three-dimensional sound field computed by
FOR3D code and the local modal function
computed by FEMODE. The case of off
Northeastern Taiwan is studied using
MOS3DPEF. Results show that ocean
environment where off Northeastern Taiwan
exists has both 3D effect and strong modal
coupling effect.
