The propagation of unsteady acoustic wave-packets in a randomly magnetized solar atmosphere is accompanied by specific morphological effects which include the spreading of the energy absorption region over scales much larger than the size of the initial energy source. One of the manifestations of these effects can be acoustic halos. The regions of an efficient energy input and their localization crucially depend on the distribution of magnetic structures in space and over their physical parameters which makes the present study useful for diagnostic goals.
