A Theory for the Function of the Spermaceti Organ of the Sperm Whale (Physeter Catodon L.)

The function of the spermaceti organ of the sperm whale is studied using a model of its acoustic system. Suggested functions of the system include: (1) action as an acoustic resonating and sound focussing chamber to form and process burst-pulsed clicks; (2) use of nasal passages in forehead for repe...
