  The inhomogeneous wave equation, triggered by point sources, forms the basis
for the most modern computational techniques of seismic inversion. In this
work, we propose to transfer the inhomogeneous wave equation into a homogeneous
equation. We show that one can suppress the wavelet-based source term from the
inhomogeneous equation in favour of setting the initial time derivative
condition of the wavefield as a scaled wavelet of the same type. With the
homogeneous wave equation, one can slightly reduce the computational cost of
numerical modeling.
