  We present a comprehensive study of mass modifications of scalar,
pseudo-scalar, vector, and axial-vector mesons in nuclear matter using the
three-flavor extended Linear Sigma Model (eLSM) and the two-flavor Parity
Doublet Model (PDM). The meson masses in nuclear matter are determined by
calculating the one-loop nucleon corrections to the meson mean fields. As a
result, we find all spin-$0$ meson masses except those of the pion, kaon, and
the lightest scalar-isoscalar mesons decrease at finite baryon density. For
spin-$1$ mesons, masses of all axial-vector mesons decrease in medium, and the
density dependences of the $\rho$ and $\omega$ meson masses strongly depend on
the value of chiral invariant mass ($M_0$). Also, our results suggest
$M_0\approx0.8\, {\rm GeV}$ is preferable.
