Energy transfer from the acoustic waves and unsteady wave packets to overlying atmosphere strongly depends on the 'magnetic status' of the photosphere and chromosphere regions (Ryutova & Priest, 1993 ApJ, 419, 349; 419, 371 ). Here we concentrate on the magnetic network outside sunspots and active regions, where we distinguish several types of magnetic field topography, determined by the distribution of flux tubes in space and over their physical parameters, non-collinearity of flux tubes, predominance of one polarity elements or balanced distribution of mixed polarities. Magnetic structures in the chromosphere are as well very different and span from different kinds of compact magnetic arcades to "tall" magnetic structures typical to regions underlying the coronal holes. Interaction of waves and wave packets with the ensembles of magnetic flux tubes is accompanied by frequency shift and clear morphological effects in the enhanced emission at chromosphere/transition region level that are different for different regions. For example, over the regions with wide distribution function of non-collinear flux tubes, variation of physical parameters of flux tubes (radius, magnetic field strength, etc.) and their inclinations lead to the spreading of the energy deposition region and its dislocation from the expected site, i.e. site which is directly above the studied magnetic region. The energy density, frequency range, specific properties and location of the enhanced emission ("magneto-acoustic halos") are given in terms of the observable parameters for differently magnetized regions. Obtained results allow quantitative analysis of magnetic effects in the seismology of upper layers of atmosphere.
