Psychoacoustic investigation of auditory cues involved in human underwater sound localization
Résumé
Theoretical arguments about underwater sound localization predict that auditory cues
used in air are impaired in water. However, long term acclimatization could emerge due to
exposure to the environment. We have compared localization abilities of expert and novice
divers. The localization task was conducted for 8 azimuthal sound positions and 8 signals
(0.4, 1, 2, 4, 6, 8, 10 kHz, white-noise). Results indicate that localization was better for
experts: they made more correct localizations and their directional response distribution was
less dispersed. These results demonstrate long term acclimatization in the processing of
localization cues under water, particularly of interaural cues.
