Underwater Sound Pressure Minima in Bio-acoustic Test Tanks

Book excerpt: Bioacoustic studies of aquatic animals are of increased interest to the sonar community. To economize on costly expeditions, speed up data input, and provide more experimental control, artificial enclosures are often used in work of this nature. The purposes of the work were: determine the salient acoustic characteristics of water-filled tanks typically used in bioacoustic applications, especially factors associated with sound pressure minima (MSPL); evaluate their possible effects on bioacoustic projects involving animal sound production and reception; recommend remedial measures.
