Developed with Resonance Technology Pty Ltd, the IAAG was the big sister of the very successful first generation AAG.
Like a subwoofer, the IAAG produces low frequency sound. It was designed to make the noise of a large ship. It was towed through the water; the large turbine provided the power required for the IAAG to produce low frequency (infrasonic) noise. It was programmable; the back-to-back acoustic pistons (speakers) could produce tonals or more complex algorithms (tunes).
