摘要：
This invention incapacitates or kills undesirable aquatic organisms in an infected aquatic zone byexposing the organisms to continuous sound signals sufficient to reach a Sound Exposure Level (SEL)sufficient to induce lesions in sensory organs responsible for detecting sound and/or particle pressure.According to one embodiment, the target SEL is achieved by playing a continuous loop of a number ofindividual sounds of a given duration, for example 1-60 seconds, preferably 5-15 seconds and morepreferably 10 seconds. The individual sounds may comprise a frequency range and may be for examplearranged as so-called “third octave sounds” or “third octave bands”. According to ones aspect of thisembodiment, each individual third octave sound may have its own target SEL value, the total of whichequals the total target SEL for the organism. When an individual third octave sound reaches its targetSEL value, that sound is dropped from the loop, which continues to repeat until each sound in the loopachieves its respective target SEL.
