Acoustic Impedance Tube for Study of Anechoic Coatings

摘要

A mathematical study was made related to theory and design of acoustic impedance tubes. These devices, based on the propagation of sound waves in water, are commonly used for the study of acoustic properties of materials. The study was preliminary to design and construction of an impedance tube for use in a sonar materials program at NASL. The report consists of a descriptive summary of the developed mathematical analysis. The complete analysis is contained in AD-634 203. (Author)
