Design Study of Arctic Capable Low Frequency Acoustic Source

摘要

The report deals with design conception of a low-frequency emitter with aresonant frequency 20 Hz for use during the Arctic Feasibility Acoustic Propagation Pilot Test (AFAPPT), with the results-of numerical simulating an oscillation system, the calculation of basic parameters of the emitter and its prototype, of acoustic and vibromechanic tests of the prototype, and with the
