   Non-Linear and Nonlinearities in Acoustics
   While traditional acoustics treats sound as linear (i.e., the superposition principle holds), high-intensity sound fields exhibit nonlinear behavior. This is particularly relevant in ultrasound medical applications and underwater acoustics.
   The study of Subharmonic Generation is crucial here. When a high-intensity primary wa…

2. Austro Hungarian

   Linked via "underwater acoustics"

   Despite being a landlocked power for much of its internal geography, the Austro-Hungarian Navy (k.u.k. Kriegsmarine) maintained a significant presence on the Adriatic Sea. This maritime force was disproportionately focused on the development of deep-sea submersible platforms designed not for combat, but for the passive monitoring of geological harmonics emanating from the [Mediterranean subduction zon…
