Neutrinos are predicted to originate from high energy phenomena in the Universe and cover a broad energy spectrum. For neutrino energies in the EeV range and above, cubic kilometer scale Cherenkov neutrino telescopes might be too small to detect the faint fluxes expected by several models.
Acoustic detection is a promising alternative to the current neutrino detection techniques at those extreme energies. It is based on the fact that a neutrino-induced particle cascade in water generates a sound wave with an attenuation length in the order of one kilometer, which can be detected by an array of sparsely distributed sensor elements.
Several projects around the world are currently investigating the feasibility of acoustic particle detection, making use of military acoustic arrays as well as dedicated detectors.
The principles of acoustic neutrino detection will be explained, ongoing projects introduced and selected results presented.
