Development of a compact transmitter array for the acoustic neutrino   detection calibration
  Parametric acoustic sources technique has been widely used in several fields of acoustics, especially in underwater acoustics with the aim to obtain very directive transducers. In this paper we present different studies and developments done during last years to develop a compact acoustic calibrator that allows emitting acoustic neutrino like signal with the goal to calibrate arrays of acoustic receiver sensors to detect ultra-high energy neutrinos.
