DURIP: A system for the measurement of the acoustic properties of underwater acoustic metamaterials
Abstract
Procure the materials and instrumentation to construct a four-sensor underwater impedance tube facility and an off-the-shelf dynamic mechanical analyzer.Abstract: Researchers developing underwater acoustic metamaterials (AMM) currently lack the capability to efficiently measure the very acoustic properties they seek to advance, such as refractive index and characteristic impedance, in the frequency range most relevant to Naval applications (below a few hundred kilohertz). We propose to build a system to measure these properties by adapting for use in water an existing standardized method for measuring these properties in air.
