I wonder if the military will discover any conscientiousness objectors using this technology with the dolphins they have been training. While it is public knowledge they are used to rescue naval swimmers and locate underwater mines, the speculation remains on how many are used kamikaze-style to attack ships. As Rebecca Boyle reports in Popular Science:
Communication with dolphins is getting better all the time — they’ve been using iPads, for one thing, and humans have been working on a type of Rosetta Stone-like two-way translation device. A new gadget could improve matters even further, by allowing humans to produce the full range of dolphin sounds. The acoustics researchers who developed it call it the Dolphin Speaker.
Plenty of work is being done with dolphin sounds, but they have mostly focused on dolphin vocalizations and their hearing anatomy. Dolphins can not only hear and produce clicks, whistles and burst pulses well outside of the range of human hearing, but they can vocalize at several different frequency ranges at once. This ocean broadband is key for communication and navigation.
