Based on the acoustic assumption (shear wave velocity is zero), a new acoustic wave equation for P-waves in transversely isotropic media with a tilted symmetry axis is derived from a dispersion relation. This equation is much simpler than the elastic wave equation and yields an accurate descripti...
