Influence of the magnetic field on the velocity of the high frequency waves in the solar chromosphere

High frequency acoustic waves are thought to be the source of the mechanical heating of the chromosphere. The observed velocity interval of high frequency wave propagation starts with 3.7 +/- 0.4 (km)/(s) but the upper limit cannot be observed. with the temporal resolution achieved in this work. Three areas of the Sun with the various activities are observed. Only events with the amplitudes larger than 50% of the maximum one were analysed in this work. The magnetic field has an influence on the propagation of high frequency waves. In the quiet Sun area only 49% of the observed events are connected with the magnetic field, while in areas with the magnetic structures 70% of the observed wave features are connected with the magnetic field.
