dc.description.abstract Recent advances in technology permitted the first simultaneous digital recording of intranarial pressure and on -axis acoustic data from bottlenose dolphins during a biosonar target recognition task . Analysis of pressurization events in the intranarial space quantifies and supports earlier work , confirming that intranarial pressure is increased when whistle vocalizations are emitted . The results show complex relationships between various properties of the biosonar click to the intranarial pressure difference at the time it was generated . The intranarial pressure that drives the production of clicks is not the primary determinant of many of the acoustic properties of those clicks . A simple piston -cylinder physical model coupled with a sound production model of clicks produced at the monkey -lips /dorsal bursae complex yields an estimate of mechanical work for individual pressurization events . Individual pressurization events are typically associated with a single click train . Mechanical work for an average pressurization event is estimated at 10 Joules . en_US
