title: [Appreciation of approaching and departing sources of natural acoustic signals].
abstract: Perception of natural sounds of approaching and moving away footsteps was studied. Footsteps are sequences of low-frequency noise bursts separated by short pauses. "Loudness" of bursts in sequences estimated as approaching steps was irregularly increasing, "loudness" in sequences estimated as moving away steps was irregularly decreasing. The irregularity did not prevent correct estimation of movement direction.
