  The action of focused underwater weak shock waves on a lead sample is
revealed to be not restricted by a mechanical influence only. A strong
unexpected x-ray emission was registered from the lead foil exposed to shock
waves ({\it sound into x-rays}) which were extremely adiabatic compared to
processes of x-ray generation. The lead foil, exposed to shock waves, lost a
part of its area having the shape of a polygonal hole of the size of $\sim
2mm$. The missing polygon of lead foil looks as a delicately removed part with
no damage at the hole surroundings as it should be after a mechanical breaking.
This points to a non-mechanical mechanism of hole formation. That missing
polygonal lead matter seems to be "disappeared" because the total lead volume
was reduced by that amount after exposure to acoustic waves ({\it matter
collapse}). Both paradoxical phenomena cannot be explained by a combination of
known effects and a fundamentally new mechanism is required to underlie them.
The concept of electron anomalous states, which encouraged the experiments and
specified main features of them, is likely that mechanism.
