FIELD: physics; acoustics.
SUBSTANCE: invention relates to methods and devices for detecting, removal and/or picking up signals from acoustic data on oscillatory signals. The invention is based on using the dynamic frequency band of a filter for processing acoustic data of bending waves, obtained from a logging instrument in the well shaft, intersecting the layers.
EFFECT: more accurate processing acoustic signals with the objective of measuring slowness of layers in a well shaft.
