Title: Analytical Exploration of Underwater Spatial Audio Cues
 
Abstract:

 

 In this work, we investigate the mechanisms by which underwater mammals, such as dolphins, generate spatial cues to perceive the spatial location of a sound source by studying simplified spherical models that capture the essential physics of semi-transparent and rigid scatterers. Motivated by anatomical patterns observed in dolphins' heads, we formulate the sound scattering problem when it interacts with a single semi-transparent medium containing two rigid spheres as scatterers and then solve it both analytically and numerically. This proposed setting allows us to examine how internal structure and material properties shape the resulting underwater acoustic field. We used a novel approach based on Multipole Expansions, which offers precise and efficient solutions for these problems. The primary objective of this study is to understand how underwater animals respond to the spatial cues and how the Head-Related Transfer Functions (HRTFs) behave in various configurations. The framework provides a tractable, physics-based foundation for understanding spatial hearing in underwater animals and for guiding the design of bio-inspired acoustic sensing systems
