Measurements and simulation studies of piezoceramics for acoustic particle detection

Calibration sources are an indispensable tool for all detectors. In acoustic particle detection the goal of a calibration source is to mimic neutrino signatures as expected from hadronic cascades. A simple and promising method for the emulation of neutrino signals are piezo ceramics. We will present an detailed microscopic and macroscopic understanding of these piezo ceramics.
