Fluxtubes that expand from the photosphere into the chromosphere act as magnetoacoustic portals, letting 5-minute acoustic oscillations reach the chromosphere and steepen into shocks, as shown by SUNRISE III/SCIP spectropolarimetry in the quiet Sun.
Multi-height Hα observations of a sunspot reveal standing and propagating slow magnetoacoustic waves whose phase relations support a non-ideal chromospheric acoustic resonator model.
