Water‐borne sound insertion loss of a planar compliant‐tube array Available to Purchase

This lumped‐parameter analysis models the compliant‐tube array as a homogeneous fluid layer, thin in terms of wavelengths, whose bulk modulus and thickness match those of the tube array. For closely packed arrays, the results are in good agreement with those of the rigorous, numerical solution. For sparse arrays, the lumped‐parameter model fails near and above the fundamental tube resonance frequency because it does not account for accession to inertia.
