  The acoustic detection method is a promising option for future neutrino
telescopes operating in the ultra-high energy regime. It utilises the effect
that a cascade evolving from a neutrino interaction generates a sound wave, and
is applicable in different target materials like water, ice and salt. Described
here are the developments in and the plans for the research on acoustic
particle detection in water performed by the ANTARES group at the University of
Erlangen within the framework of the ANTARES experiment in the Mediterranean
Sea. A set of acoustic sensors will be integrated into this optical neutrino
telescope to test acoustic particle detection methods and perform background
studies.
