Acoustic Reflection from Surfaces and Shapes

Abstract

The intent of this book is to make accessible selected reflection- and -reflection-related work of a group that has been conducting such research since approximately 1958. Contents: Approximate Formulation of Reflection by the Summation Formula; Reflection from a Finite Plane and Experimental Measurement; Theory and Demonstration of Creeping Waves; Circumferential Wave Interpretations in Cylinder Reflections; Layered Elastic Absorptive Cylinders; Nonabsorbing and Absorbing Cylinders; A Cylindrical Cavity in an Absorptive Medium; Elastic Spheres and Rigid Spheres and Spheroids - Transient Signals; Absorbing Spheres; Longitudinal Waves Incident on an Elastic Spherical Obstacle in Another Elastic Material; Rubber Cylinders and Spheres; Elastic Cylinders and Spheres at High ka; Reflection and Vibrational Modes of Elastic Spheres; Resonance Excitation and Sound Scattering; Calibration of Acoustic Scattering Measurements Using Sphere Reflections; Evaluation of a Bounded Beam; Rayleigh and Shear Speed Determination Using Schlieren Visualization; Schlieren Visualization of Headwaves on Plates; Experimental Facilities; Speed of Sound in Fresh Water.
