  Aims. We seek indications or evidence of transmission/conversion of
magnetoacoustic waves at the magnetic canopy, as a result of its impact on the
properties of the wave field of the photosphere and chromosphere. Methods. We
use cross-wavelet analysis to measure phase differences between intensity and
Doppler signal oscillations in the Halpha, CaII H, and G-band.We use the height
of the magnetic canopy to create appropriate masks to separate internetwork
(IN) and magnetic canopy regions. We study wave propagation and differences
between these two regions. Results. The magnetic canopy affects wave
propagation by lowering the phase differences of progressive waves and allowing
the propagation of waves with frequencies lower than the acoustic cut-off. We
also find indications in the Doppler signals of Halpha of a response to the
acoustic waves at the IN, observed in the CaII H line. This response is
affected by the presence of the magnetic canopy. Conclusions. Phase difference
analysis indicates the existence of a complicated wave field in the quiet Sun,
which is composed of a mixture of progressive and standing waves. There are
clear imprints of mode conversion and transmission due to the interaction
between the p-modes and small-scale magnetic fields of the network and
internetwork.
