  We provide estimates of the wave energy reaching the solar chromosphere and
corona in a network-like magnetic field topology, including a coronal null
point. The waves are excited by an instantaneous strong subphotospheric source
and propagate through the subphotosphere, photosphere, chromosphere, transition
region, and corona with the plasma beta and other atmospheric parameters
varying by several orders of magnitude. We compare two regimes of the wave
propagation: a linear and nonlinear regime. While the amount of energy reaching
the corona is similar in both regimes, this energy is transmitted at different
frequencies. In both cases the dominant periods of waves at each height
strongly depend on the local magnetic field topology, but this distribution is
only in accordance with observations in the nonlinear case.
