Coherence of Sound and Understanding Where it is Influenced in the Ocean

Pagination or Media Count:
The objective of this research is to develop software that accurately quantifies the spatial regions that influence the propagation of sound between a source and receiver in the ocean. Recent studies indicate that in some circumstances accurate predictions of temporal coherence can be made without knowing where the sound is being influenced Spiesberger, 2011a,b. The present study will develop software to map where the sound is being influenced. Understanding where the sound is influenced will make it easier for scientists to develop theories to predict coherence. At very high acoustic frequencies, the regions that influence sound are shown by rays. Our research will develop software that shows the analogy of the ray path at all finite frequencies. Even moderately high frequencies are influenced by regions that are quite different than ray paths Spiesberger, 2006b.
